It is also recommended that the City study the feasibility
of relacating the weil field upriver near the Maplewood Golf
Cour�e. The study shoul.d determine the suitability of the ,�
aquifer through a test drill.ing program, evaluate ground- �
water quality, determine transferability of water rights and
impact on Cedar River flows, evaluate well field protectian
requirements, and compare the costs and impacts o� reloca- ���
�.ion with costs and impacts recammended for protection of
�he existing well field.
A study should also be done to consider �.he meri�s and com-
plications associated with having the Cedar River aquifer
declared a sale-source supply by the EPA.

+� �� SUN[MARY
The City af Rentan depends upon the Cedar River aquifer for
i„r, up to 85 percent of its water supply. The result� of an
engineering study �or the protection of that aquifer (well
field) from contamination by encroaching urban development
are reported herein. The scape of the study was as follows:
�
o Define the well field recharge area and evaluate
patential. contamination pathways hased on existzng
+r•• tapographic maps, well logs, geologic and hydra-
logic publications and reports, water quality test
reports, and other available information as pro-
� vided by the City of Renton
o Identify potential industrial, commercial, traf-
fic, and other contaminant sources that could
""�' adversely affect the well field. Evaluate rela-
tive significance of contaminant saurces identi-
fied and their potential impact on the we11 field
,r.
o Identi£y controls and actions that the City of
Renton and others could exercise �.o minimize or
�
prevent potential contamination of the well field
Existing State af Washington Department af Social and Fiealth
Services (DSHS} regulations place the responsibility for
r� protection of the City' s sources of water on the City. Re-
cent state legislatian directs the Department of Ecolog�
(DOE) , DSHS, and local government agencies �o explore and
�, implernent all possible measures for the protection of ground-
water supplies.
The upper two-thirds o£ the Cedar River drainage basin is
'�'' within the grotected Ci.ty of Seattle watershed. The lower
ane-third af the river basin, from Landsburg to Lake Wash-
ington, is not P�'4't2C'tG{� as a watershed and is therefore of
�. greater significance ta this study. Water from the entire
drainage basin may can�ribute to recharge of Rentan" s Cedar
River aquifer.
"" For purpases of this report, the boundaries of Rentan' s Cedar
River aquifer have beer� identified (Figure 2-3} as �he val-
ley walls ncartheast and southwest of the river, the bedroek
� narrows 4,OOU feet sautheast of I-405, and a line drawn
approximately 1 ,000 feet northwest of I-405. Thi� aquifer
is generally 70 to 90 feet deep, as are the five wells in
,�„ the well field.
The aquifer receives natural recharge from direct precipita-
tian infiltration, subsurface lateral and vertical discharge
""" from the adjacent plateaus on either side af the valley,
surface water runoff and seepage from the valley walls,
underflow through the bedrock narrows, and inflow from the
,.� Cedar River during flood flows.

�
Contaminants can enter the aquifer through the same flow
paths as natural recharge. Contaminants are attenuated in
the earth to various degrees, depending on the chemical _
nature of �he contaminant and nearness of the contaminant
source ta �he wells.
Water quality in the aqui£er, as sampled at the wells, cur-
rently exceeds drinking water requirements for alI param-
eters. No detailed comparison of past and present well
water quality data was made to identify trends, if any, in ��,
contaminant levels. However, water guality in the river ��
adjacent to the aquifer is not as high and does not always
meet drinking water standards. A1so, river water quality is �.�
expected ta decrease in the future as increased population �
grow�h occurs east of Renton. River water quality can
affect aquifer water quaiity. �
4
Current land use activities and potential contamination '�
incidents adjacent to the aquifer are likely ta have a more
significan� effect on water guality in the aquifer. Poten-
tial con�aminant sources have been classified as river, sub-
surface, surface, transportation, and general.
Significant river sourc�s of potential contamina�ian upstream �
of the aquifer include:
a �eptic tanks �n the Maplewood Addi�ion and in other �
developing areas upstream +�
o The Cedar Hills and Queen City Farms landfills �
o The Gull service station approximately one mile
east of I-405 alang the Maple Valley Highway �
a Overflows from Cottonwoad and Falcon Ridqe Sewage �
Pump Stations
Significant subsurface sources af potential contamination
near the aquifer include:
a Underground petroleum starage tanks and piping at �
two and possibly faur service stations
o Fuel and concrete additive staraqe tanks at the ��
Stoneway concrete plant
o �anitary and starm sewers near the aquifer
a Three private fill sites near the Mt, Olivet
Cemetery
Significant surface sources of potential cantamination nea�
the aquifer include sprays and fertilizers used in the im-
mediate vicinity of the aquifer. �

�
,wr
�r. Significant transportation sources of potential contamina-
tion near the aquifer include:
�
o Surface (stormwater) runoff from I-405, SR 169,
and city streets
o Accidental spill of petroleum products, chemicals,
*� or other hazardous materials on I-405 , SR 169 ,
city streets, and Burlington Northern railroad
tracks
�
Significant general sources of potential contamination near
the aquifer include:
'�" o Residential heating oil tanks
o Residential disposal of paints, solvents , herbi-
+r� cides, pesticides , petroleum products, and other
common but hazardous materials
,r o Chemical solvents from dry cleaning operations
Severe contamination of the aquifer could be extremely ex-
pensive. Necessary actions following contamination might
"'° include one or more of the following:
o Cleanup of the contaminated aquifer soils
w
o Isolation or diversion of contaminated aquifer
water from the City' s wells
�` o Construction of water treatment facilities
o Abandonment of the aquifer and existing supply
� facilities
o Location and development of a new source of water
�,,, supply
o Purchase of water, if available, from Seattle
Water Department
wr
Preventive measures can be implemented to protect Renton' s
Cedar River aquifer from contamination. The costs of imple-
r menting these measures must be weighed against the risks of
taking no action. Among the general methods of prevention
recommended herein are:
w�.
o Development of policies that limit land use within
the aquifer recharge area. Such policies include
appropriate zoning to limit or eliminate commercial
'� activities that are potential contaminant sources,
and the acquisition of such properties for conver-
sion to park, greenbelt or other non-contaminating
,,, u s e.
Xl
irr
o Increased participation by the City of Renton in
resolution of regional issues that may impact
aquifer protection. These issues include I-405/
I-90 and other highway planning, construction, and
traffic restrictions; continued use of and hauling
of waste to the Cedar Hills landfill; land use in �
the river basin east of the city limits; sewerage �
of outlying areas; and maintenance of minimum
stream flows in the Cedar River.
�_.�
o The Cedar River aquifer could be declared a sole- .�
source supply by the EPA at the request of the
City. The ramifications of the declaration should
be carefully considered by the City prior to making
such a request, however.
o Water table monitoring in the aquifer area to con-
firm groundwater and contaminant flow paths.
o Water quality monitoring of both well (aquifer) �
water and river water to observe trends in contam-
inant levels.
o Development of an emergency response plan to deal
with possible aquifer contamination incidents.
Among the specific methods of contamination prevention for '�
river sources recommended herein are: ,�
o Provision of sewer service for the Maplewood Addi- :
tion as soon as possible ;,,�
�
o Continued monitoring of the Cedar Hills and Queen �
City Farms landfills to ascertain leachate move-
ment patterns and the need for additional protec- �
tive measures in the future
o Modify Cottonwood and Falcon Ridge Sewage Pump
Stations as required to minimize chance of
overflows.
Among the specific methods of contamination prevention for
subsurface sources recommended herein are:
o Adoption of an ordinance that requires construction �
of improved storage facilities for hazardous sub-
stances, primarily the petroleum products at the
identified service stations (including the Gull �'
station) and the petroleum products and concrete
additives at the Stoneway plant. Ban new service
stations in the aquifer area.
X11
�
�
�
r,,, o Continued monitoring of aquifer water quality to
detect leakage from adjacent sanitary sewers, with
immediate repair of any known leaks in such
sewers. The abandoned sewers in Cedar River Park
'"' should be completely plugged
o Repair of any known leaks in storm sewers and ex-
,r» tension of storm sewers to discharge to the river
downstream of Wells 1 and 2 wherever possible.
Prevent contaminants from entering storm sewers
�, whenever possible
o Continued monitoring of the operation of the three
private fill sites near Mt. Olivet Cemetery to
""' assure that no hazardous leachable materials are
included in the fill
�. Among the specific methods of contamination prevention for
surface sources recommended herein is continued restraint by
the City, WSDOT, and BNRR in the use of herbicide and pesti-
� cide sprays and fertilizers in the vicinity of the aquifer.
Among the specific methods of contamination prevention for
transportation sources recommended herein are :
�
o Collection of surface runoff from all paved areas
of I-405 that drain toward the aquifer and dis-
w, charge of this storm sewage to the river at a
point downriver of Wells 1 and 2
� o Construction of jersey barriers along the paved
shoulders and on/off-ramps of I-405 to prevent
vehicles from spilling contaminants outside the
paved areas and to protect the well facilities
w.r from physical impact
o Control of construction activities (such as refuel-
� ing of equipment) during expansion of I-405 to
minimize chances of groundwater contamination
o Protection of the well field should be addressed
�'""' during preparation of the environmental impact
statement by k�SDOT for the I-405 expansion
,w,. o Collection of surface runoff from all paved areas
of SR 169 in the vicinity of the aquifer and dis-
charge of this storm sewage to the river down-
w
stream of Wells 1 and 2 if possible
o Construction of jersey barriers along the north
and south paved shoulders of SR 169 to prevent
«• vehicles from spilling contaminants outside the
paved areas
..

�
��
o Im lementation of restrictions on the types of
P
hazardous materials that can be transported on
I-405, SR 169 , and city streets in the vicinity of �
the aquifer
Amang �he specific methods of contamination preventian for �
general source� recommended herein are:
o �urvey of the aquifer recharge area to determine �
the nuznber of existing heating oil and mator fuel �
storage tanks; evaluation of the risk they repre- '�
sent to the aquifer, and development of a program
for minimi.zing leakage fram these tanks if neces- �
sary
o �pan�oring an education program (through inserts
in mt�nthly utility bil.lings or other means) that
informs the public af the potential consequences
of residential dispasal of hazardaus materials
such as solvents, pesticides, and petroleum products
o Provision of convenient collection centers far the
public to dispose of such materials that are unac- ;
ceptable to narmal garbage collection services `
o Monitoring aperations of any dry cleaning facili-
ties to ensure proper dispasal of cleaning solvents �
�
No guarantee is made that all potential contaminan-� sources
have been identified. Additional or improved methads of �
contamination prevention may be available or will be devel-
aped in the future. The main intent of this report i.s to
stimulate an awareness of the patential for aa,uifer contami- �
natian and that it serve as a tool toward maintaining the �
high quality of the City af Renton' s existing water source.
One option to protection af the existing well field which `�
the City should cansider is that of relocating the City' s �
we11s upriver, near the Maplewood Golf Caurse. It appears
that protection of a well field at this site from long-term ��°
contamination might be more easily accomplished. If the �
aquifer there is suitable for development af majar wells,
groundwater quality is acceptable, and the cost of relocat-
ing to that area can be justified when compared to the cost �
af well field pratection at the present site, then the Maple-
wood site might pravide the City of Rentan with a better
r�
source of water in the future.

�� INTRODUCTION
w PROJECT DESCRIPTION
Background
r�.
The City of Renton has five potable water wells that are
located in an urban setting. The wells have historically
,�,,,, produced high-quality water that consistently exceeded State
of Washington Department of Social and Health Services
(DSHS) and Environmental Protection Agency (EPA) quality
standards for public water supplies. However, the wells are
""` vulnerable to contamination because they are located near
existing commercial business activities and major
transportation corridors. Encroaching urban developments
�. and proposed highway expansions in the area encompassing the
wells increase the potential for future contamination.
� Protection of these wells is crucial to the health and
safety of the public because they are the source of
approximately 85 percent of the City' s total water supply.
Other sources of water are not readily available to meet the
'""" demands for potable water.
Well Field Description
�
The locations of the five wells , all of which draw from the
Cedar River aquifer, are shown in Figures 2-3 and 3-1 . The
wells are described in detail in the 1983 City of Renton
� Comprehensive Water System Plan. Their construction dates,
depths, and capacities are as follows:
•• Depth to
Bottom of Well
Well Date Well Screen Capacity
�,r, No. Constructed (feet) (gpm)
1 1942 82 2 , 000
2 1942 82 3 , 000
�"' 3 1959 56 1 , 600
8 1967 92 3 , 500
9 1984 105 1 ,250
�
The wells are located within two separate City of Renton
parks. Wells 1 and 2 are located at the southeast corner of
� Liberty Park, with the Cedar River approximately 100 feet to
the south and Houser Way bordering on the east. Houser Way
is a one-way arterial street bounded on the east by a single
set of Burlington Northern Railroad tracks and Inter-
� state 405 (I-405) .
�
1-1
�..
�
Well 3 is located at the northeast corner of Liberty Park,
at the intersection of Bronson Way and Houser Wa_y. Bronson
Way is a multilane arterial street with a service station �
and other commercial businesses to the north. �
Wells 8 and 9 are located directly east of I-405 within
Cedar River Park. Cedar River Park is encompassed by I-405 '�
to the west, State Route 169 (Maple Valley Highway, SR 169) �
to the north, the Stoneway concrete plant to the east, and
the Cedar River to the south. �
�
The City of Renton plans to construct additional wells in
the Cedar River aquifer as future water demands increase. �
These wells may be located near the five existing wells or
they may be located farther upriver, near the Maplewood Golf �
Course.
Purpose �
The purpose of this study was to identify potential sources �
of contamination that could adversely affect the quality of �
water produced from the wells , and to provide information on
which future decisions and actions to protect this vital
resource can be based. Recent laboratory tests on water �
samples taken from the City ' s distribution system indicate
that the water currently extracted from the wells is of ex-
cellent quality. This report identifies potential future �
sources of contamination so that preventive measures can be
implemented to maintain this quality. Therefore , the rec-
ommendations outlined in this report are preventive rather �
than corrective. �
It is unlikely that all preventive measures , even though
desirable , can be implemented. Some accidental �
contamination of the aquifer might occur even though all �
preventive measures were implemented. Further, it is
possible that contamination of the aquifer has already
occurred but has not yet been detected. The objective,
then, of developing an aquifer protection plan is to reduce
the risk of occurrence and the magnitude of possible
contamination to acceptable and affordable levels.
SCOPE OF REPORT
This report documents an investigation of the well field �
area surrounding Wells 1 , 2 , 3, 8 , and 9. The scope of the
investigation, as outlined in an engineering services ��
contract between the City of Renton and CH2M HILL, is as �
follows:
o Define the well field recharge area and evaluate �
potential contamination pathways based on existing
topographic maps, well logs, and geologic and
�
1-2 ,.��
„�
�
�s
.. hydrologic publications and reports, water quality
test reports , and other available information as
provided by the City of Renton
'r o Identify potential industrial , commercial,
traffic, and other contaminant sources that could
adversely affect the well field. Evaluate
� relative significance of contaminant sources
identified and their potential impact on the well
field
«�►
o Identify controls and actions that the City of
Renton and others could exercise to minimize or
,r.
prevent potential contamination of the well field
REPORT ORGANIZATION
�r• This report is organized in a manner similar to the scope
outlined above. The well field recharge area is defined in
Chapter 2 using available geologic and hydrologic
� information. Included is a discussion of probable
groundwater movement and surface drainage patterns.
Chapter 3 addresses the sources of potential contamination
""" and their possible impact on the well field. The impact of
each potential contaminant source is evaluated and ranked
according to parameters such as chemical content, potential
;., quantity, location, probability of occurrence, attenuation,
and detectability. A table is provided at the end of the
chapter listing each of the sources of potential contamina-
�
tion and the ranking of these parameters for each.
Possible methods of eliminating or controliing the potential
contaminant sources or minimizing their effect on the well
� field are considered in Chapter 4.
EXISTING REGULATIONS
rr
The City of Renton' s Cedar River aquifer is unique among
sources of public water supply because of its urban
location, relatively shallow depth to water surface, and the
'""' large number of customers served. Most water purveyors of
Renton' s size use surface or subsurface supplies from more
remote and protected watersheds. Other smaller local
;r communities with water sources similar to Renton' s include
Federal Way, Issaquah, and Redmond. Because Renton' s water
source is somewhat unique, there are few other existing
� guidelines or examples of aquifer protection which Renton
might follow.
Current EPA and DSHS regulations governing public water sys-
� tems are oriented primarily toward defining potable water
quality and the design and operation of water systems.

�
Neither EPA nor State of Washington Department of Ecology �
(DOE) currently has regulations specifically governing
protection of aquifers. However, the following excerpt from
DSHS ' Rules and Regulations of the State Board of Health £�
Regarding Public Water S�stems, August 1983, best identifies �
protection requirements for water sources:
�
:.�
218-54-125 Source protecHon. ��
Public drinking water shall be obtained from the highest quality source feasible. �
Existing and proposed sources of supply shall conform 10 the water quality stand-
ards established in WAC 248-54-175.
(1) For wells and springs, the water purveyor shall provide an area of sanitary �
control for a radius of one hundred feet (thirty meters) and two hundred
feet (sixty meters) respectively;excxpt the water purveyor shall control Iand
of a greater or lesser size or of a different shape than is defined by a one �
hundred or two hundred foot radius where an engineering justification has �
been reviewed and accepted by the department. The engineering justifica- �
tion must address geological and hydrological data, well construction de-
tails, and other relevant factors indicating a control area of different size or ,,,�
shape is necessary to assure adequate sanitary control in the vicinity of the
source. ,�
Within the control area, no source of contamination may be oonstruclod,
stored,disposed of,or applied without the permission of the department and ��
the purveyor. 'I'he control area must be owned by the water purveyor in fee �
simple, or he or she must have the right to exercise complete sanitary oon-
trol of the land through other legal provisions.
A purveyor owning all or part of the control area in fee simple, or who has �
possession and control of the sanitary control area,evcn though the legal ti- �
tle is held by another, shall convey to the department a restriction on the
use of the tand in accordance with these rulcs, by appropriate legal docu-
ment,such as a declaration of covenant.This document shall state no source
of contamination may be constructed,storod,disposed of,or applied without
the permission of the department and the purveyor, and if any change in
ownership of the system or sanitary control area is considered, all affected
parties shall be informed of these requirements. �
Where portions of the control area are in tha possession and oontrol of an- il�
other, the purveyor must obtain a duly recorded restrictive covenant which
shall run with the Iand, restricting the use of said land in accordance with
tl�se rules, which shall be recorded in the county wherein the land is �
located. �
(2) Adequate watershed control, consistent with treatment provided, shall be
demonstrated and documcnted for all surface water sources pursuant to �
WAC 248-54-225. A dcpartment guideline regarding watershed control is
available to assist utilities in this regard.
(3) ln situations where regional ground water resources are being utilized, col- �
Iaborative actions may be taken by appropriate local,state,or federal agen-
cies when necessary to protect underground sources of drinking water.These �
may include, but not be timited to: Sole source aquifer designation;special
design criteria;or ground water resource management.

(1) All public water systems utilizing surface water shall adequately ezercise
,�,,, surveillance over conditions affecting source water quality.
(2) Those public water systems using unfiltered surface waters shall,in addition
to subsection (1)of this section,document a watershed control program. All
facilities and activities in the watershed affecting public health shall be un-
� der the surveillance of the water purveyor and shall be satisfactorily limited
and controlled so as to preclude degradation of the physical, chemical,
microbiological,viral,and radiological quality oF the source of supply.
� (3) Those public water systems using unfiltered surface water shall submit to
the department for approval a report identifying all conditions, activities,
and facilities within the watershed, together with an acceptable program for
necessary surveillance, limitation, and control. This report shall be part of
the water system plan required in WAC 248-54-065, included in an opera-
'�"' tions program as required in WAC 248-54-195, or prepared indcpendently
for those systems not required to have such a plan. The report shall be re-
viewed, updated as necessary,and submitted to the department annually.

" As these excerpts indicate, the responsibility for
protection of the Cedar River aquifer lies primaril�� with
the City of Renton. However, the City currently has no
.. specific ordinances that focus on protection of the Cedar
River aquifer. Such an ordinance, or aquifer protection
plan, is needed to supplement existing regulations to ensure
.�.
long-term protection of this most important drinking water
source.
House Bill No. 1138 , recently enacted by the state
�"' legislature and effective June 7 , 1984 , is an act which

�� HYDROGEOLOGY
" INTRODUCTION
The City' s wells extract water from the aquifer beneath the
...�. Cedar River valley. The aquifer is a saturated stratum of
unconsolidated deposits. Water entering the aquifer from
the ground surface, or from subsurface sources, is termed
..�
recharge. The area around the aquifer that collects and
transmits significant quantities of recharge to the aquifer
is called the recharge area. Contaminants discharged or
spilled within that area can potentially cause contamination
"' of Renton' s aquifer. Therefore , protection of this area
from contaminants is of great importance to the protection
of the aquifer. This chapter describes Renton' s aquifer
�,,, recharge area and identifies potential contamination
pathways, based on existing geologic and topographic data.
�.
CEDAR RIVER DRAINAGE BASIN
Flow from the entire Cedar River drainage basin may contrib-
ute to recharge of the aquifer. The Cedar River heads in
� the Cascades at the eastern edge of King County. The upper
two-thirds of the river' s 50-mile length and 188-square-mile
drainage basin is located within the City of Seattle water-
,�, shed. The westerly limit of the Seattle watershed is at
Landsburg, where Seattle Water Department withdraws its
major water supply. The limits of the Cedar River drainage
basin below Landsburg are shown in Figures 2-1 and 2-2. The
'"`" portion of the drainage basin below Landsburg is of primary
importance to this study.
� From the topography illustrated by contour lines in
Figures 2-1 and 2-2 , major surface drainage patterns are
evident. These are limited primarily to natural flows
overland and in contributory streams. However, below (west
"` of) Maplewood Golf Course, the natural surface and
subsurface drainage patterns are supplemented by paved
streets with gutters and storm sewers in densely developed
� areas.
Several major storm sewers discharge into the Cedar River in
,r,,, the vicinity of the well field at locations indicated in
Figure 2-2. The largest of these is a 30-inch line from the
South Highlands area, which discharges to the river at the
I-405 crossing. Others include five 18- and 24-inch lines
"`" along SR 169 southeast of the well field. These five sewers
collect highway drainage and surface and subsurface water
from the Lower Maplewood area.
�
�
2-1
vn
�
Throughout the drainage basin, underlying soils formations
affect movement of subsurface water toward the river. This
is evident along the edges of the Cedar River valley between ��
the well field and Maplewood Golf Course. Here, springs ,�
emerge from the valley walls at intervals. These springs
are fed from the plateau areas northeast and southwest of ,�
the valley where surface water generally percolates into the �
ground. These plateau areas include South Highlands, Lower j
Maplewood, Heather powns, and Tiffany Park Cascade.
�
GEOLOGY i�
The limits and character of the Cedar River aquifer in the �
vicinity of Renton' s well field were determined by review of ��
topographic maps, well logs, and geologic and hydrologic
publications. Sources most helpful include the following:
o Water Supply Bulletin No. 28 , Geology and Ground- �
water Resources of Southwestern King County, Wash-
ington, 1969, by the State of Washington `�
Department of Water Resources , prepared in ij�
cooperation with the U. S. Geological Survey. The
accompanying Plates 1 and 3 of the Bulletin show �
soil formations and known well locations in the �
area.
o Boring logs for Wells 1 , 2, 3, 8 , and 9 and obser- �
vation wells for Wells 8 and 9, plus the drilling �
and testing reports for each of these wells.
��,
o Hydrologic Analysis, Renton Well 9 , 1983. �
Information from the above sources was supplemented by field ��
observations. The geology of the well field area is sum- �
marized in Figure 2-3. The following brief description of
geologic units in the area will illustrate the significance
of Renton' s Cedar River aquifer. �
The geologic units that form the Cedar River valley in the
vicinity of Renton' s well field are, from oldest to
youngest:
o Bedrock of the Puget Group
The Puget Group underlies the valley wall south- �
west of the Cedar River. It consists of highly
folded and faulted sandstone and interbedded shale �,�
and coal. In the Renton Tiger Mountain area, the �
unit includes volcanic conglomerate, siltstone ,
breccia, and lava flows. „�
o Undifferentiated Pre-Vashon Drift �
�
2-2 =�
�
w.
,,,,, This unit, underlying the valley wall northeast of
the Cedar River, is over 400 feet thick beneath
Renton' s well field. It consists of at least four
layers of till separated by river-deposited sand
'"' and gravel and lake-deposited sand, silt, clay,
and peat.
� o Vashon Till
The Vashon till varies in thickness from zero to
� 80 feet. It is a compact mixture of gravel and
boulders in a silty/sand matrix.
o Vashon Outwash
�.
The outwash unit caps the hills northeast of the
Cedar River near the well field and is from zero
� to 300 feet thick. It consists of clean sand and
gravel.
�
o Vashon Drift
This unit caps the hills southwest of the Cedar
River. It consists of undifferentiated till and
� outwash sand and gravels.
o Alluvium (Cedar River aquifer)
r..
This unit comprises the Cedar River aquifer, the
aquifer pumped by Renton' s Wells l , 2 , 3 , 8 ,
and 9. It consists of terrace and flood-plain
"' deposits of clean gravel and sand in the
Cedar River valley. The alluvium is about 70 to
90 feet thick in the well field area. The water
� table within the aquifer is generally at or near
the elevation of the water surface in the Cedar
River. In the area of the well field, the water
� table is approximately 20 feet below the ground
surface.
The areal and stratigraphic relationships of these geologic
� units are shown in Figures 2-3 and 2-4.
CEDAR RIVER AQUIFER
�rr
The alluvium is the only major water-bearing unit in the
area. The Vashon drift and outwash may support a perched
water table above the river valley near the well field, but
�" this unit has not been developed. The underlying pre-Vashon
drift has been reported to be not capable of yielding large
quantities of water in the vicinity of the well field based
°��+ on a 400-foot-deep test hole (observation Well 9) . The
�
2-3
r.
��
r�
,�
bedrock Puget Group usually yields only a few tens of i�
gallons per minute to wells.
.�
�
For purposes of this report, the boundaries of Renton' s �
Cedar River aquifer, as distinct from the drainage basin,
have been defined as the valley walls northeast and :�
southwest of the river, the bedrock narrows located about �
4, 000 feet southeast of the well field, and a line drawn �
about 1 ,000 feet northwest of Wells 1 , 2 , and 3 (see
Figure 2-3) . The bedrock narrows was chosen as the south- �
east boundary because it is believed that the alluvium is ��
thin there and most of the groundwater flowing down the val-
ley (roughly parallel to the river) is forced to the sur- ��
face. The northwest boundary was chosen to represent an ��
assumed probable maximum radius of influence (area affected
by a pumping well) of Wells 1 , 2 , and 3 based on reported �
testing of Well 9 , although the aquifer itself extends
beyond these limits. ��
As Figure 2-5 illustrates, the aquifer receives natural re- `"�
charge from direct precipitation infiltration; subsurface ��
lateral and vertical discharge from the pre-Vashon drift;
surface water runoff and seepage from the valley walls �
bounding the aquifer; underflow through the bedrock narrows;
and inflow from the Cedar River during flood flows. Water
in the alluvium generally moves down valley parallel to the
river, with a component of flow toward the river under non- �
pumping conditions. Natural discharge is to the river
and/or ultimately to Lake Washington and Puget Sound. Pump-
ing distorts the natural flow, causing water to flow roughly '"�
radially toward each well. If the aquifer becomes contam- �
inated, the contaminants must migrate to within the well' s
radius of influence before a quality problem could develop .�,
with the well water. �
CONTAMINANT FLOW PATHS
�
Contaminants can enter the aquifer system by many different �
routes. The principal flow paths are listed below and
illustrated in Figures 2-2 and 2-5. Figure 2-5 represents a �
generalized cross-section of the Cedar River aquifer at the
well field. The existing wells extend to near the bottom of
the aquifer. �
o Contaminants from direct surface sources above the �
aquifer could migrate through the soil to the
water table. �
o Contaminated Cedar River water could enter the
aquifer during flood flows (when the river level �
is higher than the groundwater level) . Entry �
could also be induced by pumping, as may be the
case for Wells 1 and 2 . Any spill or activity
_��
2-4 -:�
s
�i
r
� within the surface watershed of the Cedar River
above the narrows could conceivably contribute to
river contamination.
`' o Surface runoff/spills from South Highlands , Lower
Maplewood, Heather powns, Tiffany Park Cascade,
and the eastern portion of North Renton could
� carry contaminants to the aquifer.
o Contaminants from surface sources in the upland
� areas described above could migrate through the
soil and seep out along the valley walls or enter
the aquifer below ground.
'"�' o Leaking sewers or other pipelines passing through
(above) the aquifer area could carry contaminants
to the aquifer.
�.
Contaminants that enter the aquifer will be attenuated to
various degrees, depending on the chemical nature of the
contaminant, the nature of the aquifer materials, and
`" nearness of the contaminant source to the wells. The major
attenuation processes include sorption to aquifer materials,
chemical precipitation and related reactions ,
�w biodegradation, mechanical filtration, and dilution due to
dispersion and mixing. The inverse of attenuation is
mobility, a term used later in this report to rank
� contaminants.
Sorption (adsorption or absorption) generally is a revers-
ible process and therefore serves only to slow the rate of
�" contaminant movement relative to the water. Chemical preci-
pitation is generally more permanent. However, all
reactions are reversible to some degree. The extent of
,,,,,, biodegradation will depend on the value of the contaminant
as a food source to organisms existing in the soil.

WATER QUALITY
Renton Well Water
+� Water from Renton' s four existing wells (and from Well 9
when completed) is disinfected by chlorination prior to dis-
charge into the City' s distribution system. In accordance
,r„ with DSHS regulations, the City routinely collects untreated
(raw) water samples from each well for analysis of bacterio-
logical (total coliform) and inorganic chemical and physical
parameters. Water is also sampled for turbidity, trihalo-
"" methanes, corrosivity, pesticides and radionuclides. Copies
of recent laboratory analysis reports are included in
Appendix A. As these reports indicate, the well water
w quality (and thus the aquifer water quality) exceeds current
drinking water requirements for all parameters. No detailed
�
2-5
r..
�
"�
comparison of past and present water quality data was made �
to identify trends, if any, in contaminant levels.
Maplewood Well Water �
The Maplewood Addition Water Co-op provides water service to
the entire Maplewood Addition, including that portion inside ``�
the city limits (see Figure 3-1) . Their source of supply is �
two wells 15 to 20 feet apart, located within the residen-
tial area near the easterly edge of the Maplewood Addition. ��
Each well is equipped with a 10-horsepower, 200-gpm vertical �
turbine pump.
,,
According to a representative of the Co-op, two raw water �
samples are tested for coliform each month by the King
County Health Department. The representative stated that
the coliform counts are always below the DSHS-allowed maxi- "�
mum. A comprehensive water quality analysis is also con- �
ducted every 3 years. The latest test results from November
1982 , also included in Appendix A, indicate water quality
meeting DSHS requirements. The water quality closely �
parallels that from Renton' s Cedar River aquifer. �
Little else is known about these wells. No conclusions have ��
been drawn as to the relationship of this well water quality
with the quality of water from the adjacent Cedar River.
��
River Water �
Limited data is available on quality of water in the Cedar ,.�,
River, both adjacent to Renton' s Cedar River aquifer and �
further upstream. Potential data sources which were checked '�
include the following:
o U. S. Geological Survey
�
o Metro
o EPA (STORET system) �
o DOE �
o DSHS
o Seattle Water Department
o City of Renton �
Data from the Seattle Water Department relative to Cedar
River water is limited to water quality at the Landsburg =
Dam. A recent water analysis report for this source is �
included in Appendix A. As this report indicates , water
quality at Landsburg is considerably higher than that from �
Renton' s wells. This is as expected, due to Landsburg' s �
upstream location away from most contaminant sources, and to
the fact that ground (well) water typically contains more
dissolved inorganics than does surface (stream) water. �`�

ww
� River water quality data have been collected by U5G5, Metro,
DC?E, EPA, and the University of Washington at six locations
between the mouth of the Cedar Rzver and the town of Maple
Valley at various times from 1959 (RIBCO Water Quality
'`" Management Study, Part III, Appendix B, Water Quality
Analyses, December 1974) . EPA STORET data fram the sampling
paint at the Logan Street bridge are included in Appendix A.
w The data have nat been s�.udied in detail in prepara�ian of
this report; however, they would be useful baseline data for
future river water quali�y analyses and determination of
�.
cantaminant trends.
In qeneral, the available histarical data indicate that, in
the lawer Cedar River below Maple Valley, water quality
"'"' condi�ions frequently violate Washington State 4�a�er Quaii.ty
Standards for C3ass A wa�.ers or simil,ar standards suggested
in the RIBCO Water Qua2ity Management Study. {The DdE
„�, classifies the Cedar River from Lake Washington ta Lanclsburg
Dam as Class A excellent, suitable for domestic, industrial ,
and agricultural water supply, among other uses. )
`" High temperatures and low di�salved oxygen concentrations
have been noted during low fl.ow conditions isummer) . Exces-
sive �otal co2iform caunts (c�ue to nonpoint saurces} have
� been abserved at various times year round. High
nitra�.e-nitrogen cancentrations have been nt�ted in the
win�er months, ap�arently from nonpoint sources, and exces-
� sive concentrations of phosphate-phospharus are a1s�
believed to occur.
Computer-modeled projections of future water quality condi-
'"" tions �to the year 2000) were made during the RIBCO WQMS
wark, assuming no significant change in the Iand uses af the
watershed upstream of Landsburg and that no point sources
„�,,,, would discharge ta the Cedar River in the future. The
madeling simulated changes in land use (increased papulation
densi�.ies) below Landsburg. I� indicated that, even wi�.h
� greater papulatian, river water quality condi�ian� will not
be �ignificantly degraded in the future. Only coli�orm
bacteria showed significant increases to year 2000;
inorganic chemical and physical parameters and B4D were not
+� predicted to change significantly,
In conjunction with this well field protection study, the
;�,,,�, City of Ren�on sampled Cedar River water at Cedar River Park
in March 1984 . The laboratory analysis repart, included in
Appendix A, indicates levels of coliform and inorganic
chemical and physical contaminants similar to the level�
"' found in the well water. One sample, however, is nat a
reliable indicator af river wa�er quality which fluctuates
frequently.

�
It may be concluded that, at present, water in Renton' s �
Cedar River aquifer is of good quality and is considerably
better than that in the Cedar River. Sufficient data do not >�
exist to document any current trends in river water quality, �
nor does the scope of this report permit development of
additional data. �

�� POTENTIAL CONTAMINANT SOURCES
""' INTRODUCTION
This chapter discusses in detail the potential contaminant
�.,, sources identified by the study. For discussion purposes,
the sources are organized into the following general
categories:
`�" Subsurface
These are sources of contamination that originate below the
+r�+ ground surface, such as leakage from a buried tank or pipe-
line. Contaminants from subsurface sources may remain en-
tirely belowground or they may eventually seep to the
,�„ surface along the valley walls.
Surface
`�'" Contaminants from surface sources originate on or above the
ground surface and migrate to the aquifer via infiltration.
�rr Rive r
River contaminants flow with the surface waters in the Cedar
�, River. They originate as either subsurface or surface
sources east of the bedrock narrows, as noted in Chapter 2,
or as direct discharges to the river.
'�" Transportation
Contaminants from runoff and accidental spills related di-
„�, rectly to transportation are organized into this category.
General
�" These sources of contamination can be either subsurface,
surface, or river sources but have not been pinpointed to a
specific site.
�
The potential contaminant sources that are identified with
specific locations are listed and shown in Figures 2-2 and
,r,r, 3-1. The locations of the City' s wells and city limits are
also shown in these figures.
EVALUATION PARAMETERS
Irr
The degree of impact each contaminant source may have on the
quality of water produced from the wells is dependent upor.
,rr many factors. The principal factors are as follows:
o Chemical content of material
�
3-1
�
o Potential quantity involved
o Location of contaminant source with respect to the
aquifer and the probable direction of groundwater
movement
o Probability of occurrence
o Attenuation, including sorption, chemical pre-
cipitation, filtration, dilution, and biodegrad-
ation as discussed in Chapter 2
o Ability to detect occurrence of and direct
movement of a spill or leak before contaminant
reaches the wells
The potential impact that each contaminant source may have
on the well field can be estimated by evaluating each of
these factors. Table 3-2 , found in the summary of this
chapter, lists each of the potential contaminant sources t
identified in this study and ranks the impact of each.
RIVER SOURCES
Contaminants from these sources generally originate up the
Cedar River valley a minimum of one mile to the east of the
wells. Although contaminants in this category may originate
on the ground surface or subsurface, they would reach the
Cedar River and eventually flow with the surface waters of
the river as they enter the shallow upstream end of_ Renton' s �
Cedar River aquifer at the bedrock narrows. Also included
in this category are direct discharges of raw sewage to the
river caused by overflows from two pump stations located
west of the narrows.
Under normal conditions, it is thought that such contami-
nants in the river will not have an adverse impact on the �
aquifer unless the quality of water in the river is degraded
for a long period of time, or unless flooding conditions or
excessive well pumping cause the contaminants to move from �
the river into the aquifer. �
Septic Tanks
According to City of Renton sewer maps, most of the devel-
oped areas within the city limits are served with sanitary
sewer connections. Generally, areas to the east of Renton' s
city limits , are on septic tanks. One area of particular
concern that is not sewered is the residential development
known as the Maplewood Addition, which is directly south of ,.A�
the Maplewood Golf Course between the Maple Valley Highway �
and the Cedar River. The entire area is not sewered, al-
though approximately one-third of the area is within the
city limits. �
3-2 ,�
�
�
r
� Each residence is on a separate septic tank. There are
approximately 200 residences in the area with 145 of these
in the portion that is outside the city limits. The Seattle
Metro Cedar River Trunk interceptor sewer bounds this parcel
�"" of land to the north but the development is not connected to
it.
i.r The development is in a 100-year flood zone according to
U.S. Department of Housing and Urban Development flood
insurance rate maps. Flooding of this area could result in
,�, raw sewage being carried down the Cedar River from submerged
septic tanks and drain fields. As mentioned in Chapter 2,
the normal groundwater flow patterns are generally parallel
to the river or from the aquifer toward the river. However,
'�" under flooding conditions, this natural flow pattern may be
interrupted. Thus, contaminants carried downriver during a
period of flooding could reach Renton' s wells.
r
As noted in Chapter 2, water service to the Maplewood Addi-
tion is provided by two wells located within the residential
area. Although test reports indicate water quality meets
�" DSHS requirements, these test results may not represent the
water quality when a flood condition exists.
�• In addition, there are numerous other residential develop-
ments upstream of Maplewood, even beyond the town of Maple
Valley, which are served by septic tank systems. These
� developments are located both in the Cedar River valley and
on the plateaus to the north and south, in varying densities
and sizes. Some indication of the extent of such develop-
ments appears on the base map (USGS map) used for Figure 2-2 ,
�"' although the map was last updated in 1973.
Because of the nature of the soils near the surface in these
r areas, it has been found that most septic tank systems do
not perform satisfactorily after 10 to 12 years of service.
King County sanitarians have indicated that the rate of
� septic tank failures in the entire Cedar River drainage
basin probably exceeds 30 percent. According to the RIBCO
Water Quality Management Study, Part III, Appendix A, Sewer-
age Analysis and Plan, population in the basin between Ren-
� ton and Landsburg is expected to double to approximately
50, 000 in the years between 1980 and 2000.
,r,,,, The existing Metro Cedar River Trunk interceptor sewer ends
just east of Maplewood at the intersection of the Maple
Valley Highway and 149th Avenue SE. Extension of this
interceptor sewer upriver for a distance of approximately
'�"' 2. 5 miles is anticipated by 1990. Further extension to the
town of Maple Valley is not anticipated until after 1990.
r�. Construction is scheduled to begin under a ULID in June 1984
which will connect the developments in the vicinity of the
�r.
3-3
.�.
Aqua Barn Ranch to the Metro sewer. The King County Build-
ing and Land Development Department has no knowledge of a
proposed commercial development in the vicinity of 140th
Place SE at Maple Valley Highway. However, should such
development occur, it should also be connected to the Metro
sewer.
Until Maplewood and other residential developments upstream
are connected to sanitary sewers, an increase in coliform
count and nutrients (such as those found in commercial
fertilizers) from failing septic tank systems can be
expected to occur in the Cedar River. Contaminants from
septic tanks are among the most serious of the potential
contaminants categorized as river sources.
Landfills
There are two existing solid-waste landfills approximately
7 miles east of Renton within the Cedar River drainage
basin. The locations of these sites are shown in
Figure 2-2. The Cedar Hills landfill is operated by the
King County Solid Waste Division. Queen City Farms is a
private landfill, located directly to the south of the
Cedar Hills landfill, that no longer accepts waste for
disposal.
Because of natural drainaqe patterns, the majority of sur- `
face runoff and leachate from those landfills flows into
Issaquah Creek rather than into the Cedar River. Typical
leachate characteristics include low pH, low dissolved
oxygen, high coliform, BOD and COD levels, increased hard-
ness, and increased levels of inetals, salts, nitrogen and
phosphate. All of these characteristics are highly undesir-
able in a potable water supply, as well as harmful, if not
deadly, to aquatic life in the river. A table of typical
leachate characteristics is included in Appendix B.
The Queen City Farms site is on the U.S. Environmental Pro-
tection Agency hazardous waste site priority list. Sites
included on this list are subject to future study and pos- �
sible cleanup by the EPA. The EPA has found high levels of
contaminants in the groundwater beneath ponds located on the
Queen City Farms site. Tests using an organic vapor �
analyzer have been performed at approximately 40 private �
well sites in the area encompassing the landfill. The tests
indicate that groundwater contaminants at these sites are
below the maximum contaminant levels (MCL) set by the EPA.
Tests to determine the direction and rate of movement of the
contamination plume are continuing at this time.
The EPA believes that contaminants that leach from either of
these landfill sites would not be at measurable levels once
they reached the Cedar River.
�

�
rr
,�, Gull Service Station
A Gull service station is located approximately one mile to
the east of I-405 along the Maple Valley Highway. This site
�"' is located beyond the eastern boundary of the City' s aquifer
(the bedrock narrows) as described in Chapter 2 . Therefore,
product leakage from this site would probably migrate to the
�rr surface of the Cedar River and have little, if any, effect
on Renton' s aquifer under normal river flow conditions. The
contaminants associated with service stations and their
� potential impact on water quality are discussed in detail in
the following section on subsurface sources.
Sewage Pump Station Overflows
1rr
There are two sewage pump stations located within the aqui-
fer recharge area that include emergency overflows to the
,�,,. Cedar River. They are the Cottonwood pump station, located
north of the river to the east of the Stoneway Concrete
plant, and the Falcon Ridge pump station situated south of
r
the bedrock narrows.
Emergency overflows typically discharge raw sewage to adja-
cent waterways when power failures occur at pump stations or
rrr when the influent flows exceed pumping capacities , causing
overflow of the wetwell.
� Details of design and construction of these pump stations
were not obtained. It is believed that discharge from these
overflows is infrequent and that the resulting contaminants
in the Cedar River would continue to flow downstream without
'�" adversely affecting the aquifer.
Olympic Petroleum Pipelines
..
Olympic Pipeline Company operates two petroleum pipelines
that cross the Cedar River just west of the Maplewood Golf
� Course. These pipelines are 16-inch- and 20-inch-diameter
cathodically protected steel. They are buried and carry
refined petroleum products. Because the pipelines are
located east of the bedrock narrows, it is probable that
+�+ petroleum product leakage would flow on the surface of the
Cedar River without degrading the quality of water in the
aquifer.
�wr
Miscellaneous
No point discharges (contaminant sources concentrated at a
�"" single point) of any consequence are known to exist upstream
in the Cedar River valley. Besides failing septic tank
systems, other nonpoint sources not mentioned above which
w� contribute to water quality degradation include urban
runoff, horse and cattle pasturage, and logging.
�.
3-5
�
Urban runoff (storm sewage) is discussed in the Transportation
Sources section of this chapter. As urban development in-
creases in the river basin, an increase in storm sewage
contaminants in the river can be expected. Horse and cattle �
pasturage is expected to decrease as urban development in-
creases. The Aqua Barn, located one mile east of Maplewood,
presently has the largest concentration of horse pasturage �
in the basin. Contaminants from logging, primarily sediments,
are not thought to threaten Renton' s aquifer and are more
readily controllable than other contaminant sources. �
SUBSURFACE SOURCES
Contaminants that originate below the ground surface, such �
as leakage from a buried tank or pipeline, are categorized
as subsurface source contaminants. Because these sources
are out of sight, immediate detection of leakage or impending
danger is often difficult and may require special equipment.
Contaminants from subsurface sources may remain entirely
belowground or, if the source is in the upland area, they
may eventually seep to the surface along the valley walls.
Service Stations �
Service stations within the aquifer recharge area pose a
continuous threat to the quality of Renton' s water supply.
Leaks from buried fuel storage tanks or piping can release
quantities of petroleum product without immediate detection.
Even small quantities of petroleum product can contaminate
large volumes of water. Harmful components generally found �
in petroleum products include hydrocarbons, tetraethylead, ;
ethylene-dichloride or ethylene-dibromide, benzene, EDB, and
various gasoline detergents. The range of effects that
these components may have on water quality covers a broad �
spectrum. Some components may only produce adverse taste
and odors in the water while others may be carcinogenic when
ingested. �
Because most fuel storage tanks and pipes are constructed of
steel, they are subject to corrosion. Failure of these �
vessels at service stations within the Puget Sound area is
not uncommon. There have been incidents in the cities of
Auburn and Seattle within the past year. Crowley Environ-
mental Services, a local firm that specializes in the cleanup �
of hazardous material spills, reports that they have been
directly involved in cleanup activities at 35 to 40 service
station sites in the Puget Sound area. They indicate that �
most of the leaks they have encountered at service stations
have been associated with failures of buried piping to the
fuel dispensing units rather than failures of the storage
tanks. Failure of steel pipes due to corrosion is a common
occurrence.

■.
� Leakage of petroleum near the wells could cause serious
contamination of the aquifer. Petroleum product would rap-
idly migrate vertically through the permeable soil to the
� water table. The product would then float on the surface of
the water table, spread laterally, and could possibly be
drawn into the well.
'�" Cleanup of petroleum spills is extremely difficult. Total
excavation of the contaminated soil is sometimes required to
restore groundwater quality. Continuous pumping of a con-
,.� taminated well to a waste site may also be required to pro-
tect other wells in the vicinity from contamination. Often,
additional wells must be drilled to continuously monitor
groundwater quality around a contaminated well. Efforts to
r"" clean up petroleum contamination can be very expensive and
their results are not always successful. Therefore, in
addition to the potentially serious health effects, a petro-
+� leum product spill within the aquifer recharge area could
have enormous economic consequences.
� The potential for a major petroleum tanker truck spill
during transportation and unloading also exists. This is
discussed further in the "Transportation Sources" section of
this chapter.
rrr
Generally, small surface spills of fuel and motor oil drip-
pings at service stations in the area are collected by the
�w storm drainage system. Special catch basin traps are
normally used to contain these minor spills. Therefore,
they are not considered to be a major threat to groundwater
� quality.
Service stations near Well 3 are the most obvious cause for
concern. A Texaco station is located approximately 150 feet
� directly to the north of Well 3 on Bronson Way. This
station has four 6,000-gallon gasoline storage tanks , a
550-gallon waste oil tank, and a 1 ,000-gallon heating oil
,W, tank. All of the tanks are buried, are of steel construc-
tion, and have been in service for nearly 17 years. Buried
steel piping on the site connects the storage tanks to a
total of six fuel dispensers.
�r
The average quantity of gasoline dispensed from this station
each month is 150 , 000 gallons. Inventory control at this
�w site includes stick gauging the storage tanks on a daily
basis and reading the meter on each dispenser. Records are
kept on the premises indicating the daily inventory on hand,
� the quantity of fuel dispensed, and the net gain or loss
from inventory. Cumulative records from April 1983 through
February 1984 indicate the following:
�r
�rr
3-7
�..
o A loss of 307 gallons from the premium unleaded
gasoline inventory, representing an average
monthly loss of 27. 9 gallons
o A loss of 1 , 281 gallons from the regular unleaded
gasoline inventory, representing an average
monthly loss of 116. 5 gallons
o A gain of 1 , 191 gallons in the regular gasoline
inventory, representing an average monthly gain of
108.3 gallons
According to these statistics, the average monthly loss from
the total inventory at this site is 36. 1 gallons per month.
Losses are not necessarily attributed to leakage. Evapo-
ration, temperature variations, pilferage, and limited accu-
racy of storage tank gauging practices are all factors to be
considered when analyzing petroleum product inventories.
A Union Oil station is located approximately 500 feet to the
west of Well 3 . This facility has two gasoline storage
tanks including a 5,000-gallon tank that is 25 to 30 years
old and a 6,000-gallon tank that is 10 to 15 years old.
There are also three 350-gallon diesel fuel tanks and a
waste oil tank of undetermined capacity on the site.
The average quantity of gasoline dispensed from this station
each month is 12 ,000 gallons. Inventory control includes
stick gauging the storage tanks approximately 3 times per
week and reading the meters on the dispensers each day. The
operator of this facility states that the total quantity of
fuel indicated on the dispensers for the last 12 months
equals the total quantity of fuel delivered to the site in �
the same period.
An abandoned service station and an Exxon service station
are located approximately 1 ,200 feet to the northeast of
Well 3 at the intersection of Sunset Boulevard and North
3rd Street. These stations may not be as critical to the
safe operation of the well field system as the previously
mentioned sites. It is probable that they are located
beyond the radius of influence of the wells.
Texaco, Inc. , recently filed an application for a new condi-
tional use permit from the City that, if approved, would �
have allowed Texaco to remove its existing facility and
install new facilities on the same site. The proposed new
facilities included a service station, a car wash, and a
convenience store. These plans also included removing the
existing buried tanks and installing one 12 ,000-gallon and
two 10,000-gallon gasoline storage tanks. In addition, a
10 ,000-gallon diesel fuel storage tank was to be installed.
3-8
�
�+ Each of these tanks would have been constructed of fiber-
glass. New buried fiberglass piping would have connected
the tanks to a total of 12 fuel dispensers under the
�, proposed plan.
This proposal represented a major expansion of fuel storage
and dispensing facilities on the site. Marketable product
�"'� storage would have been increased by 75 percent over present
capacities. Fuel dispensers and related buried piping would
have been doubled. Texaco has stated that the amount of
i,,,. fuel dispensed from the upgraded facility would remain at
the present 150 ,000 gallons per month. Texaco' s application
was denied by the City' s land use hearing examiner, as was
� their appeal to the city council. According to City records,
the denial was primarily due to limited space on the site,
which necessitated the use of a public alley in order to
conduct normal business.
�
A public hearing was held on January 17 , 1984, prior to the
decision of the City' s land use hearing examiner. A staff
,,,,,, report was prepared prior to the hearing with input from
various City departments. The staff report addresses the
City' s concern regarding the relationship of the service
station to the water supply system. The report notes that
'r" Well 3 is approximately 100 feet from the southern border of
the service station property and also states that "any spill
or contamination of the ground by a leak in the gasoline
� tanks could result in a major public health hazard. " The
close relationship between the well and the existing service
station facility is a valid concern.
w�r
To reduce the risk associated with a petroleum spill , the
staff report recommended that Texaco be required to install
an electronic leakage monitoring system around the storage
�"' tanks. Such a system would provide a means for early detec-
tion of a tank leak. Early detection may help in reducing
the quantity of petroleum product lost into the ground.
r. Prompt notification of a leak would also allow the City to
discontinue pumping operations, thus possibly preventing the
product from reaching the water distribution system. An
early detection system will not prevent a leak from occur-
�` ring, nor will it guarantee that the product will not reach
a well. Such a system will also not reduce the long-term
threat of aquifer contamination associated with a service
�+ station or eliminate the need to clean up contamination
should leakage occur.
� Concrete Plant
The Stoneway concrete plant that is located approximately
1 , 100 feet to the east of the City' s wells is a potential
""' source of serious contamination. Petroleum products and
�
3-9
�
chemical additives for concrete are stored in bulk quanti-
ties on the site. A pond for disposal of concrete slurry is
also located on the site. As stated in Chapter 2 , the
groundwater in this area probably flows parallel to the
Cedar River. Contaminants from this site that infiltrate
through the alluvium to the water table would flow in the �
general direction of the wells. Thus, the entire well field �
is vulnerable to contamination from this site.
Materials stored onsite to be used as concrete additives �
include the following:
o Zeecon, which is a water reducing agent made from
wood pulp byproducts and is stored in a 5,000-
gallon tank
o A polymer-base water reducing agent manufactured
by Master Builders (MB Pozz 322N)
o Approximately 1 ,000 gallons of Master Builders
MB AE-10 air entraining aqent
o Calcium chloride stored in a 2 , 000- to
3 ,000-gallon aboveground tank
o Master Builders 122 HE, which is an accelerator
containing calcium chloride in combination with a `�
water reducing agent
o A retardant, which is basically a sugar or organic
material
According to the Master Builders factory in Cleveland, Ohio,
the chemical compositions of these admixtures are proprie- �
tary. However, some information about these products was
obtained. The MB Pozz 322N water-reducing agent is
primarily a carbohydrate with an organic amine that is also
used in soaps. The MB AE-10 air entraining agent is a wood
pulp byproduct resin that is neutralized with sodium
hydroxide. This particular agent is believed to be water �
soluble. The MB 122 HE accelerator is a combination of �
calcium chloride and a carbohydrate water-reducing agent
with a trace of an organic amine.
From this information, a determination of the impact that
leakage of these materials would have on the water system is
not possible. It does appear, however, that these materials
are water soluble and biodegradable and may therefore be
readily dissolved and diluted to harmless levels.
The slurry pond that is located on the site would also con- �,
tain these chemicals; however, they would be significantly
diluted.
�
3-10
�
�,�. Steel tanks containing petroleum products on the concrete
plant site include:
� o A buried 4 ,000-gallon regular gasoline tank
o Three buried unleaded gasoline tanks totaling
6,000 gallons
r.
o Two buried 10 , 000-gallon diesel fuel tanks
,,,,,� o A 500-gallon aboveground waste oil tank
This facility dispenses approximately 1 , 500 gallons of
�
diesel fuel per day. Stoneway indicated that in comparison
the quantity of gasoline dispensed is relatively low. Inven-
tory control consists of stick gauging the storage tanks
twice each week. Gauging is done primarily to confirm that
� there is available space in the tanks to accept fuel deliv-
eries. Records for the previous 12 months indicating the
quantity of fuel delivered to the site versus the quantity
,�, dispensed have been requested from Stoneway by letter.
Stoneway indicated verbally that this information would be
made available; however it was not received. This infor-
mation could be used to calculate the annual and monthly
"�' gain or loss from inventory.
As discussed previously, storage of petroleum products
rr� within the aquifer recharge area poses a major threat to
Renton' s water supply. The concerns outlined for the
service stations near Well 3 in the previous section also
� apply to the Stoneway concrete plant. However, leakage from
the fuel facilities at the concrete plant could cause
serious contamination at all of the well locations , not just
one well in particular. Contamination of this magnitude
� would have disastrous effects on the City of Renton.
Contrary to the belief of some, Stoneway' s manager indicates
,M that they do not have plans to relocate their facilities or
change their current operations within the next 5 years. He
says that a rumor relating to a potential relocation has
been circulating for several years. The products listed
�"` above are essential to the operation of the concrete plant;
therefore, use and storage of these products on the site
will continue as long as the plant remains active.
�
Brick Plant
� The North American Refractories Company brick plant is
located south of the Cedar River, approximately 1 , 000 feet
to the southeast of Well 8 . According to the plant manager,
they have two petroleum product storage tanks on the site.
"� These include a 1 ,000-gallon gasoline storage tank and a
vertical 100 ,000-gallon aboveground diesel fuel storage
tank.
�.
3-11
r.
The gasoline storage tank is buried and of steel construc-
tion. It was internally inspected for signs of corrision
last year; no specific problems were noted.
The diesel storage tank is relatively new, according to the
manager. The perimeter of the tank is diked to contain
leakage as required by the Uniform Fire Code. The ground
surface below the tank is covered with gravel. The maximum
quantity of fuel stored in the tank averages around 5,000
gallons.
These particular petroleum facilities are not considered to
be a major threat to the City' s wells. Because the large
storage tank is located aboveground, leakage would be 2
detectable in a timely manner. Also, it is probable that
leakage from either of these tanks would surface along the
south bank of the Cedar River and flow downstream without
affecting the groundwater quality north of the river. '�
In addition to the petroleum products , chemicals used to
manufacture fire brick are also stored on the site. These
chemicals include sodium silicate solution, trisodium phos-
phate, and aluminum sulfate.
The sodium silicate solution is stored in a 4 ,000-gallon
buried steel tank. It is completely soluble and is some-
times used as a coagulant aid in potable water treatment
plants. The trisodium phosphate is a dry chemical stored in
bags on the site. This chemical is sometimes used in indus-
trial and potable water treatment plants to reduce corrosion
and to control scaling.
Aluminum sulfate is also a dry chemical that is stored in
bags on the site. This chemical, commonly known as alum, is
often used as a coagulant aid in water treatment processes.
None of these chemicals is harmful in potable water systems
in dilute solutions. They are not considered a threat to �
the Cedar River aquifer.
Sanitary Sewers �
Sanitary sewers within the vicinity of the wells are poten- �
tial sources of contamination. Raw sewage from a ruptured �
sewer pipe is a serious threat to public health. Outbreaks
of typhoid fever, gastrointestinal infection, infectious
hepatitis, and other waterborne diseases are frequently
associated with sewage spills.
There are relatively few sanitary sewers in the vicinity of
the wells. Fortunately, the sewers that do exist are not
force mains. Force mains under pressure from a pump or
hydraulic head would pose a greater threat to the safety of
the aquifer than do the existing gravity sewers.
�
3-12
�
+�r Most of the sewers in the area range from 6 to 15 inches in
diameter. Th�se City of Renton sewers are located along
Houser Way and Bronson Way to the north end of Cedar River
� Park. Abandoned sewer lines also exist within Cedar River
Park. These abandoned lines may serve as open conduits,
allowing surface contaminants to migrate toward the wells.
y"" The largest sewer in the area, however, is the Seattle Metro
Cedar River Trunk Section No. 1. It is a 42-inch-diameter
line that traverses Liberty Park north of Wells 1 and 2 ,
�„ continues along the southern and eastern boundaries of Cedar
River Park, and extends up the Cedar River valley toward
Maple Valley as shown in Figure 3-1 . It is made of concrete
pipe and was constructed in 1962 and 1963. The average
�"" depth of the pipeline is approximately 10 feet below the
ground surface.
�• The pipe was oversized to provide for discharge from future
developments up the valley. Because the flows in the pipe
are low at present, the current contamination risk is also
�„ reduced. As areas east of Renton are developed, flows
through this pipeline will increase. Therefore, the impact
that failure of this pipe will have on the water supply is
also increasing. Concrete sewer pipe is inherently not leak
'"" tight. Some infiltration and exfiltration are expected even
with a new installation. The existing pipe is 20 years old.
As the pipe gets older, the probability of leaks through
rr either the pipe wall or pipe joints will increase; however,
no specific leaks are known at this time.
w
Storm Sewers
As discussed in Chapter 2 , ground surface slopes and en-
closed storm sewers provide pathways for storm water contam-
�' inants to flow toward the aquifer. Surface drainage in the
area flows naturally toward the Cedar River valle�� from the
adjacent hillsides. The drainage basins are shown in
r, Figure 2-2 .
Typical stormwater has many of the same characteristics as
effluent from a secondary sewage treatment plant, except
" that it often contains higher concentrations of lead, iron,
settleable and suspended solids, petroleum products, and
coliform organisms. A table of typical stormwater charac-
�.r teristics and a comparison with secondary sewage treatment
plant effluent is included in Appendix B.
� Leaks from storm sewers or open drains in the aquifer area
pose the same threat of contamination to the aquifer as
leaks from sanitary sewers. Although the danger of con-
tamination by infectious disease is much reduced, contamina-
"" tion potential by metals and petroleum products is greater
than from sanitary sewage.
r.
3-13
�
Cemetery Sites
There are two existing cemeteries on the hill to the north-
east of the well field. These are Mt. Olivet and Greenwood
Cemeteries. It is probable that groundwater from this area
migrates to the well field area. Contaminants in the leach-
ate from these sites could include dissolved organics and
inorganics and bacterial and viral organisms.
Water quality tests on samples taken from the City' s wells
indicate that the levels of these contaminants are below
DSHS maximum contaminant levels. It is probable that any
contaminants leaching from the site are attenuated through
filtration and biodegradation. The risk factor associated
with aquifer contamination from these sites is therefore
believed to be low.
Private Fill Sites
There are three private fill sites located approximately
3,000 feet to the northeast of the well field. These sites
are in the general area between the Mt. Olivet and Greenwood
Cemeteries. The individual sites are operated by Mt. Olivet
Cemetery, Emma Cugini, and M. A. Segale, Inc.
The Mt. Olivet Cemetery fill site is directly to the north
of their existing burial grounds. The existing fill mate-
rials at this site may include excess or waste soils from
construction projects, gypsum board, household appliance
frames, and miscellaneous building demolition debris, as
well as other materials. It is understood that the fill
operations at this site have been temporarily suspended, but
they may continue in the future upon renewal of the fill and
grading permit.
Permits were issued by the City of Renton in 1982 allowing
the fill operations at the Cugini and Segale sites. Cugini
is permitted to import 150 ,000 cubic yards of fill material
and excavate 30,000 cubic yards of gravels. The permit
expires in 1987. The fill materials allowed at this site
are not defined in the city hearing examiner' s report. The
report notes that this fill and excavation operation will
involve approximately 4, 000 truckloads of materials. ,_
The permit issued to Segale allows a gravel pit area to be
filled with 1 , 100,000 cubic yards of materials. The city
hearing examiner' s report notes that this fill operation
will involve approximately 44,000 truckloads of materials.
The examiner' s approval of the fill permit for the Segale
site stipulates that:
3-14
�
� "No material may be incorporated in the site which
contains soluble poisons or other leachable compounds
which have the potential for contaminating the ground-
water. "
r.
This permit also expires in 1987.
,,,,r The examiner' s estimations of the number of truckloads to
complete the work at each of these sites may be low. Even
so, close monitoring of all the materials transported to the
sites in the 48,000 truckloads cited by the examiner is not
� possible. The origin and content of all fill material may
be unknown. Although one of the above permits specifically
precludes the depositing of "leachable compounds, " it is
• possible that some contaminants such as waste oils and waste
household products such as paints, cleaners, and pesticides
may be delivered to these sites. Other disposed materials
,�,,,, such as the gypsum board, building demolition debris , and
household appliance frames may develop leachable compounds.
Because of the permeable soil conditions, contaminants from
"" any of these sites could find their way into the aquifer as
leachate in the groundwater or surface runoff.
�+ SURFACE SOURCES
Contaminants that originate on or above the ground surface
� include herbicides, pesticides , and fertilizers . Urban
runoff and accidental spills are also specific types of
surface source contamination; however, these are discussed
in the "Transportation Sources" section of this chapter.
�
Sprays and Fertilizers
w„ Pesticides, herbicides, and fertilizers are used in the
immediate vicinity of the wells. Entities using these prod-
ucts include the City of Renton Parks and Recreation Depart-
ment, Washington State Department of Transportation, and
� Burlington Northern Railroad, as well as private parties for
residential maintenance. Table 3-1 notes the products that
are known to have been used in the immediate area of the
�• wells and those who have reportedly used them.
Also noted on Table 3-1 are the generic chemical names of
j,,, some of these products, along with toxic designations or
comments. The LD or lethal dose 50 noted in the table is
defined as the ca�I�ulated dose of a substance which is ex-
pected to cause death of 50 percent of an entire defined
"""' experimental animal population. The experimental animal is
noted and the lethal dose is given in milligrams of constit-
uent per kilograms of animal body weight. This indicates
,. the relative toxicity of the various products listed.

.,,�, These products are approved by the U.S. Environmental Pro-
tection Agency for use by the general public. Generally,
this means that, if they are used at the dilution rates and ,
dosages recommended by the manufacturer, they are not pres-
" ently known to be a serious threat to public health. Lim-
ited use of any of these products may not have a measurable
effect on local groundwater quality. However, prolonged use
�+ of these products or dosages greater than those recommended
by the manufacturer may have a detrimental effect on local
groundwater quality and hence on water quality in the Cedar
�„ River aquifer.
The synergistic or combined effect of these chemicals on the
environment is uncertain. The chemical industry is con-
�""' stantly developing additional organic chemical products for
use as herbicides and pesticides. Research to determine the
health effects of these products in drinking water in vari-
�. ous combinations and concentrations has not kept pace with
their development. Many products commonly used in the past
have recently been found to have serious effects on public
� health, and their use has since been restricted. Future
research may show that products commonly used today may also
be unsafe.
+wr Fertilizers are used by the Parks and Recreation Department
on the lawn areas of the parks. Nitrates in fertilizers are
poorly attenuated and can therefore be transmitted to the
„M,,, aquifer. The DSHS maximum contaminant level for nitrates is
10 mg/1. Excessive nitrates can affect the ability of blood
in the body to carry oxygen.
� EDB is a chemical that has been used in some areas of the
state to control worm festations around berry and potato
fields. The use of EDB has recently been restricted by the
+w U. S. Environmental Protection Agency because of its harmful
effects on the environment. The Washington State Department
of Agriculture is currently developing a list of sites
� within western Washington that may be contaminated due to
the use of EDB. According to the Department of Agriculture,
there are no sites currently identified within the Cedar
River drainage basin where EDB has been used.
+�r
Water quality analyses on samples taken from the City ' s
water distribution system indicate that the pesticide levels
,.. in city water are well below specified DSHS maximum contami-
nant levels (see appendix for sample report) . Nitrates and
other fertilizer components are also reported to be well
�
below specified DSHS maximum contaminant levels.
TRANSPORTATION SOURCES
rw The City' s wells are located near major transportation
routes and are therefore subject to contamination from
accidental chemical and petroleum product spills. These
r.
3-17
�
�
transportation routes include Interstate 405 (I-405) , State
Route 169 (SR 169) , numerous city streets, and the Burlington
Northern railroad tracks.
There are currently no regulations specifically intended to
protect the wells that restrict the types of materials
transported in the well field area. The only regulations
that are known to exist are Federal Interstate Commerce
Commission regulations that restrict the movement of certain
substances such as radioactive materials. Chemical and
petroleum products are currently transported through the
well field area.
Normal precipitation runoff may carry contaminants from the
roadways that could infiltrate to the aquifer, causing
degradation of the City' s water supply. The runoff coeffi-
cient for paved areas ranges from 0. 90 to 1. 00. This means
that approximately 95 percent of the moisture that falls on
paved roadways will drain off either to the surrounding
unpaved ground or to a storm sewer system. The runoff co-
efficient for unpaved areas with light vegetation, such as
the lawn areas of the parks, unpaved roadway shoulders, and
embankment slopes, ranges from 0. 10 to 0. 50. Therefore, as
much as 90 percent of the runoff moving to unpaved areas
could be absorbed by the underlying soils and potentially
infiltrate to the aquifer below.
Potential runoff contaminants could include motor oil drip-
pings, fuel leakage, tire wear products, and exhaust precip-
itates such as lead. Leakage from transport vehicles , such
as solid waste transfer station container trucks, could also
be a source of potential contaminants. Containment of road-
way runoff is therefore critical to the protection of the
aquifer.
Interstate 405
Interstate 405 is a four-lane limited access freeway which
bisects the well field from north to south. Wells 1 , 2,
and 3 are 250 to 300 feet west of the freeway. Wells 8
and 9 are along the eastern border of the freeway. They are
70 to 80 feet from the pavement edge. I-405 is a major
corridor between southern suburban Seattle and the commu- �
nities east of Lake Washington. Because I-405 is a link
between Interstates 5 and 90, as well as a bypass of Seattle
and the I-90 tunnels, it is a popular commercial truck
route.
A potential contamination incident involving a commercial
truck occurred in September of 1983. A 1 ,500-gallon petro-
leum tanker truck overturned on I-405 between the north end
of the Renton S-curves and SR 169. The tanker was carrying
diesel fuel and gasoline. Approximately 500 gallons of
�
3-18
�
arr
��. petroleum product were reported to have leaked from the
vehicle. According to the City of Renton Fire Department
Incident Report, the spill was contained with temporary
� dikes near the accident scene away from the unpaved should-
ers. However, some of the product flowed to the paved me-
dian strip between the opposing lanes of the freeway where
it entered a storm drainage system and was discharged to the
'M Cedar River.
Absorbent pads were used on the surface of the river to
�„r, collect the product at the outlet of the drainage system.
Additional product was collected at the mouth of the river
by a Boeing Company oil boom. It is not known what fraction
of the total quantity of spilled fuel infiltrated into the
""' underlying soil through cracks and openings in the pavement.
The spill has not caused measurable effects on the quality
of water produced from the wells. Product that did infil-
�• trate underlying soil could possibly result in contamination
of the aquifer in the future.
� The potential for a similar, yet more serious, accidental
spill incident exists . The freeway is at a higher elevation
than the surrounding topography. The same tanker truck
could have overturned on the outside traffic lane and rolled
'r" over the embankment. The side slopes of the freeway are not
covered with an impervious material. Accidental spills from
the freeway could infiltrate these exposed slopes , or the
r" level areas at the bottom of the slopes, and cause serious
contamination of the aquifer.
� Drainage from the existing elevated concrete structures over
the Cedar River and SR 169 is not plumbed directly to the
storm sewer system. Runoff from these structures is chan-
neled to downspouts which drain freely to the exposed ground
w below. This condition represents a potential source of
contamination. During a previous resurfacing project on
I-405, an asphalt emulsion tack coat was allowed to run into
�,,, these downspouts and caused pollution of the Cedar River.
The ground surfaces under these downspouts are not paved and
the shoulder areas of SR 169 under I-405 collect much of the
runoff from this overpass structure. Standing water and
`'' extremely muddy conditions exist in the shoulder areas dur-
ing rainstorms.
�• Many of the storm drainage catch basins located along the
I-405 corridor in the well field area are connected to a
30-inch storm sewer that originates on the hillside to the
� northeast of the well field. The storm sewer discharges
into the Cedar River directly beneath the I-405 S-curve
structure. Contaminants from accidental spills and freeway
runoff are discharged directly into the river. Wells 1
'"' and 2 may be vulnerable to contaminants discharged in this
area.
w.
3-19
�.
The existing I-405 storm sewer system also includes open
ditches in the area of the exit from northbound I-405 to
westbound Bronson Way. Runoff collected by catch basins on ;�
the freeway above is discharged to these shallow ditches and �
is allowed to run across the ground for approximately 50
feet before entering a collection basin. The ditches are
shallow and overgrown with vegetation and do not adequately �
contain runoff. During rainstorms this area becomes sat- �
urated with contaminated runoff. In a recent storm, the
water being discharged from a pipe directly north of SR 169
on the east embankment of I-405 was observed to be gray in
color, indicating high concentrations of oil emulsions and
other contaminants.
Aside from the risk of contamination, the pump station
structures over Wells 8 and 9 are also vulnerable to direct
impact of vehicles careening from the freeway. The existing
chain link fence would not withstand the force of a large
vehicle which could severely damage the well structure and
the equipment inside. The buildings house chlorination
facilities in addition to the pumping equipment. Thus, the
potential for chlorine leakage also exists during such an
accident.
The Washington State Department of Transportation (WSDOT) is
currently planning a project which would add a high-occupancy
vehicle (HOV) lane in each direction of I-405. A meeting
was held with the City of Renton, WSDOT, Washington State
Department of Ecology (DOE) , the Department of Social and
Health Services (DSHS) , and CH2M HILL to discuss the current
and future effects of I-405 on the well field and water �
quality. The minutes for that meeting are included in
Appendix C. �
An environmental impact statement (EIS) is being prepared by �
WSDOT to specifically address the effects of the I-405 ex-
pansion project on the area between the South Renton inter-
change and the Sunset Boulevard interchange. The draft EIS
is scheduled to be completed by October or November of 1984.
According to WSDOT staff, advertisement for the construction
bids is scheduled for 1987. This proposed work may provide �
the opportunity to incorporate certain well protection safe- �
guards into the freeway design.
�
According to WSDOT, there are 12 design concepts that are
currently being considered. Basically, in the vicinity of
the well field these concepts include widening of the
existing S-curve structure, relocating the alignment to the
east of the existing roadway, and relocating the alignment
to the west of the existing roadway. Various vertical
alignment alternatives are being considered with each of
these concepts. Alignments relocated to the west or east
might conflict with the existing well locations.

,,,, State Route 169
SR 169, also known as the Maple Valley Highway, is a four-
lane roadway north of Wells 8 and 9 and perpendicular to
'� I-405. This highway connects the rural communities east of
Renton to the urban portions of King County. Traffic vol-
umes along this route are high, especially during morning
r and evening peak periods. The shoulders along this roadway
are wide and unpaved near the wells. As previously dis-
cussed, surface runoff from these shoulder areas and acci-
� dental spills can infiltrate into the ground and cause con-
tamination of the aquifer.
City Streets
w
Wells l , 2 , and 3 are bounded by Bronson Way to the north
and Houser Way to the east. Each of these streets is a
�,,, major arterial. Concrete curbs and gutters, catch basins ,
and storm sewers collect precipitation runoff on both edges
of the paved surface. The major contaminant concern is that
of potential accidental spills. As mentioned earlier, there
�"" are service stations near the wells in this area. Trucks
carrying bulk quantities of petroleum products are certain
to travel in this vicinity. Because of the proximity of the
w» I-405 entrances and exits , other types of commercial trucks
transporting potential contaminants most probably also use
these streets. There are no alternative traffic routes for
�,,, these vehicles.
Burlington Northern Railroad
""` There are two existing railroad lines within the well field
area. A north-south line lies between Houser Way and I-405.
This line joins with an east-west line south of the Cedar
�,,,, River. The maximum allowable speed of trains on these lines
within the city limits is 10 miles per hour.
According to a Burlington Northern representative, both of
'� these tracks are used on a limited basis. The track that
lies between I-405 and Wells l , 2 , and 3 is used primarily
to transport goods to and from the Safeway Company in
"� Bellevue. This line may also be used for spur traffic to
Boeing, Pacific Car and Foundry Company, and smaller busines-
ses west of I-405. Approximately two trains per day use
,,,,, this track six days per week.
The tracks that parallel the Cedar River on its south bank
are used primarily for transporting timber products to and
�" from the Weyerhaeuser Company mill near Snoqualmie Falls .
Approximately four trains per week pass this area south of
the wells. This line is also used for spur traffic to the
�r. North American Refractories Company brick plant.
,�.
3-21
�
An exact account of all materials transported on either of
these tracks is not available without extensive research,
according to Burlington Northern. It is conceivable that
goods transported to the Safeway distribution center in �
Bellevue could include household detergents, sprays, and
other toxic substances. Paints, acids , and solvents could
be transported to the Boeing and Pacific Car and Foundry
facilities.
Burlington Northern has indicated that the City may obtain
information regarding the substances transported by submit-
ting a formal request. The company will then assign a
person from their staff to review the weigh bills associated
with the trains using these routes and compile a list of
materials transported.
Because of the relatively slow speed limit and the reported
limited use of these tracks, the risk of a major rail acci-
dent is minimal. Further research of the materials trans-
ported through the area may reveal, however, that additional
restrictions should be imposed.
The railroad tracks cross the Cedar River in several places
east of Renton. These crossings are all to the east of the
City' s aquifer as defined by this report. Accidental spills
at these crossings could cause contamination of the Cedar
River. Similar to "River Sources" discussed previously in
this chapter, contaminants in the river would likely, under
normal river flow conditions, continue to flow downriver
past the well field without affecting the quality of the
groundwater near the wells. However, flood conditions or
influence from an operating well may cause this natural flow
pattern to be interrupted. Should such a spill occur, it is
recommended that the City closely monitor the groundwater
quality and direction of movement for potential signs of
contamination.
GENERAL SOURCES
General (nonpoint) sources of contamination are those that
are not identified with a specific site at this time. They
could originate as either subsurface or surface sources and
could also be associated with river sources.
�
Coal Mines
There are numerous existing and abandoned coal mines within
the Cedar River drainage basin. Abandoned coal mines have
been implicated in numerous groundwater/surface water con-
tamination cases in the Midwest and eastern United States.
Coal mines pose a contamination hazard because coal was
deposited under anaerobic, or oxygen deficient, conditions.
Mining exposes these deposits to atmospheric oxygen and
3-22
�
�
,�„� oxygenated water, which will oxidize certain minerals and
other substances present in coal. The most serious problem
is usually caused by pyrite (FeS ) a mineral which upon
oxidation will release ferric ir�n, sulfate, and hydrogen
'�" ions , resulting in acidic drainage from the coal mine.
Acidic water could lower the pH of surface waters , endanger-
ing aquatic life, or could mobilize certain ions , such as
w. arsenic, which had previously precipitated onto sediments as
relatively insoluble hydroxides.
� Moreover, abandoned mines sometimes serve as convenient
disposal sites for unwanted materials. These materials
could include hazardous substances. Because of the illegal
nature of this kind of activity, it is difficult to assess
°i" the location and number of sites that may be involved. Coal
mines are generally located in the southeastern portion of
King County east of the limits of the City' s aquifer. These
,.. contaminant sources would be classified as river sources,
and the risk associated with the sites would therefore be
reduced.
� Residential Heating Oil Tanks
Buried heating oil storage tanks within the recharge area
�► may also have adverse effects on the aquifer water quality.
The harmful components of heating oil and the effects on
water quality are similar to those stated for fuel storage
�„ tanks at service stations. Similarly, the same concerns
relative to storage tank construction and corrosion apply.
A comprehensive inventory of all home heating oil storage
"" tanks within the recharge area is not possible within the
scope of this study. A list of residences that have oil
burners within the area could possibly be obtained from fuel
,�, oil distributors in Renton; however, the completeness of
such a list would be questionable. It is likely that aban-
doned heating oil tanks exist in the area in addition to
� those currently being used.
The City may wish to conduct a survey of the residences in
the area to determine the location, capacity, and age of
'� buried heating oil tanks. Such a survey should also con-
sider private storage tanks for gasoline or other motor
fuels. The risk associated with tanks found within the area
,,,� could then be evaluated based on the criteria used herein to
evaluate other potential sources of contamination.
�
Residential Use and Disposal
Improper use and/or disposal of household, garage, and gar-
den materials such as paints , solvents, herbicides , pesti-
�r. cides, motor oils , and other substances by residential con-
sumers may have an adverse effect on the quality of water in
�.
3-23
�.
>,�
the City' s aquifer. Disposal of many of these substances in
�
the typical residential customer' s garbage can or at a public
solid waste landfill or transfer station is prohibited. �
Many individuals are unaware of the location of proper dis- ,�
posal sites and the ramifications of improper use and/or
disposal of these substances. Although illegal, disposal of
unwanted hazardous liquids into an adjacent storm sewer
catch basin or directly onto the ground is common practice.
The risks associated with these practices are dependent upon �
the substances involved, the distance and direction from the
aquifer, and soil conditions. Prevention of aquifer con-
tamination from these sources is difficult, and total �
elimination of the risks associated with these sources would
be economically infeasible.
Dry Cleaners '�
,�
Chemical solvents used in dry cleaning processes are ex-
tremely harmful to potable water supply systems. Improper �
disposal of residual solids removed from dry cleaning equip-
ment can cause serious contamination of the aquifer. For
example, the City of Tacoma has recently been involved in
the cleanup of an aquifer because of contamination caused by �
dry cleaning solvents. This cleanup operation has been ex-
tremely expensive.
�
An investigation of the immediate area surrounding the well �
field has not identified any dry cleaning establishments.
It is probable, however, that there are such businesses
within the boundaries of the aquifer recharge area.
SUMMARY
�
The potential contaminant sources identified and discussed
in this chapter are listed in Table 3-2 . The evaluation
parameters discussed at the beginning of this chapter are
used to rank each contaminant source according to its poten-
tial impact on water quality in the wells. The rankings are
defined as follows:
o High. This designation indicates that , based on
the single parameter, the contaminant source
listed may have a severe impact. "�
��
o Medium. This designation indicates that, based on
the single parameter, the contaminant source
listed may have a moderate impact.
o Low. This designation indicates that, based on
the single parameter, the contaminant source
listed may have a minimal impact.
�
3-24
.�
�
�
rr, o Unknown. Insufficient information is known about
the contaminant to assign a relative significance
to this parameter.
"" The last column in Table 3-2 indicates the overall relative
significance of each contaminant source as a threat to the
water quality in Renton' s Cedar River aquifer. Protective
� measures should be implemented to reduce the contamination
potential from all sources with a ranking of high and from
most sources with a ranking of inedium. Those sources ranked
� low in overall relative significance probably do not require
additional protective measures at this time.

� Potential Contaminant Sources
rr
+■► �� Chapter 4
�� CONTAMINATION PREVENTION
w.
INTRODUCTION
The consequences of severe contamination of the aquifer
'�" could be extremely expensive and complicated. Severe con-
tamination in this case means an increase beyond specified
maximum contaminant levels of any one or more physical,
•• chemical, biological, or radiological substances in the aq-
uifer water. Existing water treatment, limited to chlor-
ination, would not be effective in treating most, if any, of
� the identified potential contaminants.
Depending on the nature of aquifer contamination, necessary
actions might include one or more of the following:
�
o Cleanup of contaminated aquifer soils by excava-
tion and replacement
�
o Isolation of contaminated portion of the aquifer
by construction of underground slurry walls or
�
barriers
o Diversion of contaminated aquifer water through
well field injection of higher quality water or
+� pumping to waste that water removed from existing
or new wells in the area
�,,, o Construction of water treatment facilities to op-
erate in conjunction with existing supply facil-
ities
`""' o Abandonment of Cedar River aquifer and existing
supply facilities
ir. o Location and construction of alternative well fa-
cilities in the Maplewood aquifer or other area
aquifers (assuming such sources were available and
� were not already contaminated to the same degree)
o Short- or long-term purchase of additional water
supplies from Seattle Water Department or adjacent
`�"" water districts, if such supplies were available
Preventive measures can be implemented to protect Renton ' s
,�„ Cedar River aquifer from future contamination. Potential
contamination sources and their relative significance have
been identified in the previous chapter. This chapter will
discuss and recommend possible methods of eliminating these
"" sources of potential contamination or ways to minimize their
effect on the quality of water in the aquifer. General
ir.r
4-1
w�.
methods of contamination prevention are first discussed,
followed by methods applicable to specific contaminant
sources. Controls and actions that the City of Renton and �
others can exercise are discussed. Contaminant sources are
discussed in the same sequence as in Chapter 3.
�
It should be reiterated that the City' s existing well water �
quality is excellent according to recent laboratory analysis.
Therefore, the recommendations outlined in this chapter are
preventive rather than corrective measures.
GENERAL METHODS
,�
Section 248-54-125, Source Protection, in DSHS' Rules and j�.
Regulations (see Chapter 1) could be interpreted to require
that the City of Renton "control land of a greater. . . �
size. . .than is defined by a one hundred. . . foot radius" from �
the existing wells. The City now controls the two parks
which generally surround the wells for a distance consider-
ably more than 100 feet. However, the City currently has �
limited control of the I-405 corridor, SR 169 right-of-way, �
and private properties within the geographic area covering
the aquifer. The City has even less control over the
remainder of the aquifer recharge area.
Preventive Programs b� Others
To the extent possible , the City should control land use and
activities within the aquifer area. Examples of such con-
trol, or lack of it by others , include the City of Issaquah, �
which has a land use ordinance protecting two wells adjacent �
to I-90. The City of Spokane is considering protective ordi-
nances and sewerage of a low-density rural area outside the
city to protect its aquifer. Centralia, Kent, and Federal
Way all have well supplies (aquifers) within their suburban
areas but to date have not developed protective programs. ;�
Land Use i�
Policies that limit land use within the aquifer recharge
area offer Renton one of the most effective means of pre-
venting aquifer contamination. Such policies include appro-
priate zoning to eliminate commercial activities that may �
degrade the groundwater quality. The pollutant controls for
the area near the wells should be similar to those outlined
in WAC 248-54-225 (see Chapter 1) for a watershed providing
unfiltered surface water supply, wherein all facilities and �
activities are limited to preclude degradation of the water
supply.
The City of Renton has expressed a desire to establish such
a regulated area around the existing well field. The Com-
prehensive Land Use Plan adopted by the City indicates that
4-2 �'
�
irr
�„ much of the land east of the wells and bordering the Cedar
River is designated for recreational or greenbelt use. Fig-
ure 4-1 illustrates the extent of these recreational and
greenbelt areas. Powerline rights-of-way and other proper-
�"' ties having similar use are also indicated on the figure as
greenbelt use.
rw The recreational or greenbelt designations are compatible
with the aquifer protection concept. However, there are
adjacent commercial land use areas designated by the plan
� which may require additional control. These include the
areas directly to the north and east of the wells. To maxi-
mize protection of the aquifer, it is recommended that com-
mercial businesses in these areas be limited to nonpolluting
� activities.
Existing businesses which currently engage in activities
,r,,, that threaten the aquifer include the service station sites
near Well 3 and the Stoneway concrete plant east of Cedar
River Park. As discussed in the previous chapter, the pe-
troleum products stored below ground at these sites are a
�'"' continual threat to the groundwater quality. The Stoneway
plant is especially important because of its location up-
stream from the wells.
r
One means of eliminating these sources of potential contam-
ination would be for the City to purchase the property where
�, these businesses are located. Although initial acquisition
of these parcels would be expensive, commercial or residen-
tial developments that are more environmentally compatible
with the City' s aquifer protection program could be estab-
�"` lished on these sites to partially or totally offset the
acquisition expenses, or the properties could be converted
to additional park use or greenbelts.
�
The political ramifications and the effect of such acquisi-
tion on the City' s tax base must be considered by the City.
� These factors, although important, must be weighed against
the potential loss of water supply due to accidental con-
tamination of the aquifer. Should contamination of the aqui-
fer occur, other sources of potable water are not readily
� available to meet the current demand. The assurance of
future reliability of this water source will be determined
by a city government that is dedicated toward protecting the
,�„N well field system.
Regional Issues
�"' Several regional issues are of particular concern to Renton
insofar as protection of the aquifer. These include :
irw o I-405 planning and construction
�
4-3
r.�
::�
o I-405/I-90 traffic restrictions '�
o Continued use of the Cedar Hills landfill for solid "�
waste disposal and the hauling of waste to this �
site
�
o Land use in the county east of the city limits, �
including residential, commercial, industrial, or
other development and the resulting suburban
stormwater runoff
o Sewerage of the outlying rural/suburban areas
a::�
o Maintenance of minimum stream flows in the Cedar �
River
Some aspects of these issues are discussed in more detail �
later in this chapter. In general, it is recommended that �
the City of Renton be actively involved in the public debate
and resolution of all such regional issues impacting the �
Cedar River aquifer. �
For example, in the planning process for widening and possi-
ble realignment of I-405, the City should take the necessary
steps to ensure that all feasible improvements associated
with protecting the aquifer from I-405 contaminant sources
are included in the final design. The City should have a
voice in any decision regarding restriction of hazardous
materials transportation through the I-90 tunnels west of
Lake Washington. Such a restriction would force the in- '��
creased use of I-405 for transport of these materials. The ��
April 30, 1984, letter from City of Renton to Washington
State DOT included in Appendix C is a first step in such
active involvement. �
The City should participate in any decisions regarding the
continued use of the Cedar Hills landfill and should closely �
monitor ongoing studies relative to leachate from this site. �
The City should also participate in decisions regarding the
route that solid waste transport trucks follow through
Renton to Cedar Hills. At present these trucks make approx-
imately 150 trips per day along SR 169 from the I-405 inter-
change. Alternative routes for these trucks should be ;�
considered in view of the potential contaminant spills from
these vehicles. �
The City should participate in decisions relative to land °�
use in the developing areas east of the city limits within +�
the Cedar River basin. Such land use will have a signifi-
cant impact on stormwater runoff to the Cedar River and on
the future need for sanitary sewerage in the area. The City
should work with Metro and other agencies to encourage the
extension of sanitary sewers as early as possible. Other
M�
4-4 b�
�
irr
,� county regulations such as those governing septic tanks,
mines , and private disposal sites should receive input from
Renton.
�""" The maintenance of minimum stream flows in the Cedar River
is a concern not only of Renton but also of the State Depart-
ment of Fisheries, the Seattle Water Department, the Corps
rr of Engineers , and others. Renton' s interests are best served
by maintenance of higher minimum stream flows that tend to
dilute the concentration of contaminants in the river and in
the aquifer replenishment. Recreational use of the river
`� upstream of the City, as it affects water quality, is also a
concern of Renton.
�► The City of Renton could declare the Cedar River aquifer a
sole-source supply. Such a declaration, according to the
EPA, would prevent the use of federal funds on any project
�,,,, within the aquifer recharge area unless it could be shown
that the project would have no negative impact on the aqui-
fer. Before declaring the Cedar River aquifer a sole-source
supply, the City should carefully consider the merits of
"' such declaration against the possible complications to other
city projects or interests.
+r Water Table Monitoring
At present there is insufficient information to clearly
� establish the relative elevation of the water table in the
well field area and other parts of Renton' s Cedar River
aquifer with the water level in the river. Such information
would be very useful in confirming groundwater and contami-
'r""' nant flow paths in the aguifer area. Presently it is not
known whether the aquifer is contaminated; all that is known
is that no contaminants have yet reached the wells.
�
It is recommended that the City develop a comprehensive wa-
ter table monitoring program. Such monitoring should meas-
ure water table elevations at all five producing wells, at
'� the adjacent observation wells , and at additional 2-inch
observation wells located at key points throughout the aqui-
fer area and around the perimeter. Initial observation
+r wells should include several near the service stations and
the Stoneway concrete plant; these should be installed as
soon as possible. The 2-inch observation wells could also
� be used to sample groundwater quality routinely or in event
of a suspected contamination leak or spill.
The water table at each observation point should be moni-
'M"' tored monthly or at such other time intervals as experience
indicates. River level should always be noted for compari-
son, as should the duration and rate of pumping at each well
,,., preceding the time of water table monitoring. The procedure
should note fluctuations in river level due to storm runoff.
�
4-5
� .
The monitoring program should also permit evaluation of sea- �
sonal fluctuations in the water table and, in particular,
should address the impact of low river flows in the summer
and occasional flood flows in winter. Special emphasis
should be given to the relative water levels in Wells 1 and 2
and the river because of the proximity of these wells to the
river. %�
Initially, one year of water table monitoring should be suf-
ficient to confirm groundwater flow paths and direction of
major recharge. Subsequent monitoring every few years would
be useful to determine long-term trends or to monitor im-
pacts of changes in pumping rates or river flow rates. Un-
�
til groundwater flow paths are confirmed, it is futile to
monitor groundwater quality at points other than the wells.
Water Qualit� Monitoring
It is recommended that the City compare all well water qual-
ity data collected within the past 10 years to observe any �
possible trends in aquifer water quality. Such comparison �
should continue to be made in the future and may give advance
warning of a coming water quality violation.
A relatively continuous record of river water quality has
been obtained at the sampling point near the Logan Street
Bridge (see Appendix A for copy of data from EPA' s STORET �
system) . However, many of the water quality parameters of
interest for potable supplies have not been monitored at
this point. In addition, this sampling point is downstream ,�
of the aquifer. River water quality here may not represent
the quality of river water adjacent to the aquifer. The �
ideal location to monitor river water quality as it may im-
pact aquifer water quality is believed to be at the bedrock
narrows at the upstream end of Renton' s aquifer. Although
it is understood that some water quality sampling has been
done near this point by the University of Washington, the �
extent of the data is unknown. �
The RIBCO Water Quality Management Study recommended a per- t,�
manent water quality monitoring station at river mile 9 . 5 ,
near Cedar Mountain. The status of this station is unknown.
Since Renton' s Cedar River aquifer lies generally between
river mile 1. 5 and 2. 5 , river water quality from considerably
farther upstream is of less value.
It is recommended that the City periodically sample river
water at the bedrock narrows. Sampling should be as fre-
quent as once per month and correlated with river flows.
Parameters to be tested monthly should include those normally
tested for raw water samples taken at the wells--bacterio-
logical and inorganic chemical and physical. In addition,
samples should be tested quarterly for trihalomethanes and
�
4-6 �
:,
�
�
�, pesticides. It is not believed practical to monitor water
quality in tributary streams of the Cedar River.
Random river water samples are of little value because they
"r""" may show one or more abnormally high contaminants at any
time because of one-time occurrences. The quality of river
water samples should be compared over time to establish any
irr trends. These samples should also be compared with other
historical river water quality data and with well water
quality to establish any correlations. Since movement of
water in the aquifer is much slower than movement in the
"�` river, trends in river water quality may give advance warning
of coming aquifer water quality violation.
� Discharge Permits
The Cedar River below Landsburg is classified under WAC
,,,,,,, 173-201-045 as a Class A freshwater river. Under the pro-
visions of this classification the following water quality
criteria must be met when waste is discharged into the water-
way by a municipal, commercial, or industrial party:
iwr
o Fecal coliform organisms shall not exceed a median
value of 14 organisms/100 ml, with not more than
w� 10 percent of samples exceeding 43 organisms/ml
o Dissolved oxygen shall exceed 8. 0 mg/1
� o The concentration of total dissolved gas shall not
exceed 110 percent of saturation at any point of
sample collection
�
o Water temperatures shall not exceed 18 . 0° Celsius
due to human activities. When natural conditions
,j,,, exceed 18. 0° Celsius, no temperature increase will
be allowed which will raise the receiving water
temperature by greater than 0 . 3° Celsius
�`` o The pH shall be within the range of 6 . 5 to 8 . 5
with a man-caused variation within a range of less
than 0. 5 units
r.
o Turbidity shall not exceed 5 NTU over background
turbidity when the background turbidity is 50 NTU
�,,, or less, or have more than a 10 percent increase
in turbidity when the background turbidity is more
than 50 NTU
'�" o Toxic, radioactive, or deleterious material con-
centrations shall be below those of public health
significance
�
�.
4-7
c�..
o Aesthetic values shall not be impaired by the �
presence of materials or their effects , excluding
those of natural origin, which offend the senses
of sight, smell, touch, or taste
In addition to these provisions , a waste discharge permit
must be obtained by the discharging organization pursuant to �
the National Pollutant Discharge Elimination System (NPDES) . i�
These permits are issued by the Department of Ecology.
According to WAC 173-201-080, no waste discharge to the Cedar
River is allowed within the City of Seattle watershed east
of Landsburg. The Cedar River is a Class AA freshwater river �
east of Landsburg. According to a DOE spokesman, a permit �
has been issued to the Seattle Water Department that allows
periodic discharges of chlorinated water downstream from
their Landsburg facility. The DOE indicates that this is �
the only NPDES permit that has been issued for the Cedar �
River.
According to the DOE, Washington State regulations prohibit
the issuance of additional discharge permits within the en-
tire Lake Washington basin. This includes all of the tribu-
taries that feed into Lake Washington. Therefore, the Cedar
River and Renton' s aquifer are legally protected from future
point source contamination discharges by municipal, commer-
cial, and industrial entities. °�
Emergency Response Plan
Regardless of the precautions the City or others may take to �
prevent spills of contaminants in the recharge area, such �
accidents may still occur. The City can minimize the impact
that future contaminant spills will have on the aquifer by
rapidly responding to contain or clean up these accidental
spills. It is possible that immediate action by the City or
others could totally avert contamination of the aquifer. �
Although certain state or federal agencies, such as the DOE �
and EPA, may have the overall responsibility of protecting
r.
the environment, the City must take the lead in such sit-
uations and not rely on others to protect the water supply.
The City is familiar with the supply system and the precau-
tions necessary to protect it from potential contamination. �
To ensure that response to such accidents is immediate and
effective, it is recommended that the City develop an emer- �,
gency response plan specifically directed toward protecting �
Renton' s aquifer. The plan should clearly delineate the
tasks necessary to protect the aquifer from various sources
of contamination. The plan should then identify the agen- ��
cies that have the resources to perform those tasks. These i�
agencies could include various city departments as well as
x�
4-8 fn�
�
�rr
;r,n, county, state, and federal agencies. It is possible that
certain private organizations offering specialized services
should also be incorporated into the plan.
""`' The key to such a plan is not necessarily to define who does
what, but rather, what needs to be done and what resources
are available to do it. Obviously, certain tasks may re-
rrr quire resources that only one agency can provide. A properly
drafted plan will identify those tasks in advance and pro-
vide for immediate notification of those specific agencies.
'"� The American Water Works Association Manual No. M19, Emer-
gency Planning for Water Utility Management, is an excellent
guide for developing an emergency response plan. The docu-
�' ment not only provides suggestions for protecting against
contamination but also offers guidelines to water utilities
for dealing with other natural and man-caused disasters.
�
In addition to containment and cleanup of accidental spills ,
the emergency response plan should include measures to pro-
tect nonpolluted wells , should only portions of the aquifer
�" become contaminated. It may be necessary to continuously
run the pump in a contaminated well to prevent migration of
the contaminant to other wells. The discharge from the
■w+ contaminated well must not only be isolated from the dis-
tribution system in this case, but also be prevented from
returning to the aquifer.
�
The quantity of water stored in the City' s reservoirs may be
crucial in the event of aquifer contamination. Reservoir
capacities in a water system are generally determined by the
�""" number of service connections, sources of supply in the sys-
tem, historical water demands , and water reserved for fire-
fighting. The City of Renton currently has six reservoirs
r. with a total capacity of 12. 5 million gallons. As mentioned
in Chapter 1 of this report, Renton' s Cedar River aquifer
currently provides 85 percent of the City' s total water sup-
� ply. Loss of this source of supply because of contamination
of the aquifer could cause rapid depletion of stored water.
The emergency response plan should include procedures to
+� maintain high water levels in the reservoirs when aquifer
contamination is suspected. Procedures to limit water demand
on an emergency basis should also be included. Use of the
,�,,,, broadcast media to notify the public promptly, or the cur-
tailment of supplies to large industrial users, might be
necessary and should be addressed in such a plan.
'�"' The steps outlined above are only a few examples of items to
be considered when developing an emergency response plan.
The main consideration is to make those agencies that have
�w.� the available resources aware of the importance of the aqui-
fer to the City and the need to respond in a rapid manner.

RIVER SOURCE PREVENTION �
Septic Tanks
As stated in Chapter 3, contaminants from septic tanks are
among the most serious of the potential contaminants cate-
gorized as river sources. Septic tanks located within flood �
zones, potential failure of septic tank systems because of �
adverse soil conditions, and projected increases in popula-
tion densities east of Renton' s city limits are all causes
for concern. Connecting residences upstream of Renton' s
aquifer to sanitary sewer systems would increase protection
of the City' s water supply system. �
Before an area outside the city limits can be sewered, it �
must be incorporated into the King County General Sewerage
Plan and be declared a "local service area" by the King �
County Building and Land Development Division. After these �
steps have been taken, the area is eligible to connect to
the Seattle Metro interceptor sewer system.
The City of Renton currently has an ordinance that prohibits �
the connection of developments outside the city limits to
the City' s sewer system. Although this ordinance may limit
the City' s operation and maintenance costs by minimizina the
flows and size of the system, it also limits the City' s
ability to provide sewer service to the residences east of
the well field.
The Maplewood Addition residential development has been de- ��
clared a "local service area" and is eligible to connect to �
the existing Metro interceptor sewer north of the develop-
ment. It is recommended that the Maplewood area be sewered
as soon as possible to protect the aguifer from potential �
contamination. The proximity of this development to Ren-
ton' s aquifer and the possibility of flooding cause these
septic tanks to be a threat to the aquifer water quality. �
Although the Maplewood development is eligible to be sewered,
�
a project has not yet been organized. Funding for such a
project is a major consideration. The residents of the de-
velopment recently decided not to connect to Renton' s water
system because they were not willing to impose the financial
burden upon themselves. It is likely that the sewerage proj- �
ect would be more expensive than the previously proposed i�
water project.
It may be necessary for the City to sponsor a sewerage proj-
ect for the Maplewood area. This may necessitate either
annexation of the area into the City or modification of the
ordinance prohibiting city sewers outside the city limits. �
4-10 �
irr
,,,,,,, Landfills and Solid Waste Disposal
As outlined in the previous chapter, groundwater quality
monitoring is ongoing at the Cedar Hills and Queen City
`� Farms landfill sites. It is recommended that the City go on
record with the EPA and DOE that these monitoring programs
must be continued. The results should indicate groundwater
� quality trends and leachate movement patterns from these
sites. The trend data should indicate if the groundwater
quality is deteriorating and the rate of deterioration. The
,�,,, City should analyze these data as they are made available to
determine if additional protective measures must be taken in
the future.
"" The DOE has indicated that there is already sufficient leg-
islation for protecting groundwater quality in waste disposal
regulations. The coal mines and private dump sites are sub-
r.. ject to these existing regulations. Enforcement of these
regulations is therefore the key to preserving the ground-
water quality that the City already enjoys. Additional leg-
� islation should be drafted that would make individuals who
engage in contaminating activities financially responsible
for their actions. This legislation should include making
them liable for losses suffered by others as a result of
'�""' their contaminating activities.
Sewage Pump Station Overflows
r.+
It is recommended that the City evaluate the operation and
design of the Cottonwood and Falcon Ridge sewage pump
stations to determine the frequency of overflow discharges
'�`� and the quantities of raw sewage that may be involved.
Safeguards that are often incorporated into the design of
sewage pump stations to eliminate or minimize overflow of
+� raw sewage include:
o Duplicate pumps
,,,� o Backup power supply
o Increased wetwell storage capacity
o Various alarms including power failure, pump fail-
ure and wetwell high level alarms.
r
If it is determined that the pump stations discharge signif-
icant quantities of raw sewage to the Cedar River, addi-
+u.r tional safeguards that may not already be included in the
desiqns should be added.
� Olympic Petroleum Pipelines
Buried petroleum pipelines are generally designed and
constructed according to stringent federal guidelines to
� protect the environment. Aside from completely relocating,
�
4-11
�..
the pipelines out of the recharge area, which is not econo-
mically justified nor recommended, there is little the City
or others can do to lessen the already minimal risk associ-
ated with these installations. Internal pressures should be
monitored to detect losses and suspected leakage should be
investigated immediately.
SUBSURFACE SOURCE PREVENTION
Service Stations
It is recommended that the City impose regulations on the
existing service stations in the aquifer area to improve the �
protection of the aquifer. Recent legislation in California
requires that buried storage tanks for hazardous substances
be equipped with certain safeguards to protect the environ-
ment. California Assembly Bill No. 1362 requires that all
underground storage tanks for hazardous substances installed
after January 1 , 1984 , comply with certain requirements con-
cerning design, construction, monitoring systems, and
drainage. �
Petroleum products are included in the category of hazardous
substances. The specific designs for new installations in-
clude primary containment tanks with corrosion protection
and secondary containment capable of intercepting leakage
from any portion of the tank to protect groundwater. Moni-
toring devices capable of detecting leakage from the primary
containment tank are also required for new installations.
�
The legislation also requires that all underground storage �
tanks installed on or before January 1 , 1984, have a leakage
monitoring system and a means for inspection installed prior
to January 1 , 1985.
Pending California Assembly Bill No. 3565 would amend this
existing legislation to require existing tanks to also have
monitored pressurized piping systems, but it would extend
the deadline for outfitting to June l , 1985. Copies of both
Assembly bills are included in Appendix D.
Monitoring devices around single-shelled storage tanks will
provide for early detection of leakage but will not protect
the aquifer from contamination. Because of the gravelly
soils in the area of Renton' s wells and the close location
of the service stations , the petroleum product could migrate
to a well in a short time. Therefore, monitoring devices �
with single-shelled storage tanks would provide the aquifer
with little, if any, protection, and are not recommended.
`,`�
4-12
�
�rr
�r Secondary containment structures or double-walled storage
tanks would provide the most protection for the aquifer.
The California legislation substantiates the fact that the
� failure of buried storage tanks is a recognized concern. It
should be noted that secondary containment around storage
tanks does not provide protection against piping failures.
�"' Although fiberglass storage tanks and piping are considered
to be safer than their steel counterparts because they are
resistant to corrosion, they are not free from problems.
,,,,, For instance, in Auburn, a new service station was recently
built that used buried fiberglass piping. The piping was
successfully pressure tested after installation. Subsequent
W site work included constructing the concrete islands on
which the dispensers were to be placed.
While placing the forms for the concrete, a worker unknow-
� ingly drove a steel stake through the top of one of the
pipes. The work was completed, and the station was opened
for business. Approximately 8 , 000 gallons of gasoline were
�„ lost before the leak was reported. Product recovery efforts
by Crowley Environmental Services proved to be unsuccessful.
The fiberglass piping at the Auburn station was subsequently
replaced by steel piping. This case also illustrates that
'""' even leaks in relatively small-diameter piping can involve
large quantities of product and may have an enormous impact
on groundwater quality.
�.
The City of Auburn Fire Department now requires a final
pressure test of fuel piping after all construction activity
,� is completed. The City of Renton should also adopt such a
policy.
The accuracy of service station inventory control practices
""" also allows small fuel leaks to go undetected. A small var-
iation on the gauging stick can represent a significant
quantity of product. According to Texaco, the accuracy of
� inventory control varies from station to station. Improved
inventory control may be a cost-effective means of detecting
leaks at an early stage. It is understood that currently
available automated gauging systems are more accurate than
"" conventional stick gauging methods.
It is recommended that the City of Renton adopt an ordinance
+� similar to the California Assembly Bills for the specific
purpose of protecting the aquifer from petroleum contamina-
tion. The ordinance should require the following protective
,,,,,, measures for all service stations in the area within the
limits of the aquifer as shown of Figure 2-3:
�
�
4-13
.�.
o Double-walled tanks constructed on non-corrosive
material or cathodically protected steel
o Secondary containment around all piping, including �
fuel dispensing and vent lines. The secondary
containment should slope toward the storage tanks �
o Piping constructed of approved non-metallic mate-
rials or cathodically protected Schedule 40 steel
pipe
o Pressure testing of all piping after all construc-
tion has been completed �
o A device to detect product or pressure losses in
pressurized product lines �,,
o Automated storage tank gauging systems
o Observation wells with a minimum diameter of `�
2-inches, located at two corners of storage tank �
excavations
o Inventory records be maintained and reconciled
daily. Records should be made available to the
City for inspection
o Notification to the City by service station opera-
tors if fuel leakage is identified
•�
o Penalties for failure to maintain inventory proce- �
dures and records
It is recommended that all existing service stations be re- �
quired to comply with this ordinance within the next �
2 years. The Gull service station upstream of the aquifer
limits should also be required to comply. The two service '
stations near the northerly limit of the aquifer (Exxon and
abandoned station) should be required to comply with this
ordinance if groundwater table monitoring indicates that
water in the aquifer could move from the area of these
stations toward the City' s wells.
Concrete Plant
The location of the Stoneway concrete plant with respect to
the well field makes containment of potential contaminants
stored on that site critical to the safe operation of the
City' s water supply system. Contaminants entering the aqui-
fer from this site could possibly migrate to any or all of ;�
the City' s wells. �
...,-�
�
4-14 ��
1�
�
r As recommended above, the City should adopt an ordinance
that would require secondary containment and monitoring de-
vices around storage tanks for hazardous substances. The
�, definition of hazardous substances in the ordinance should
be broad enough to include any liquid or solid substance
that could adversely affect the aquifer water quality. The
California bills refer to other California legislative docu-
r"' ments to define hazardous substances. It is clear that pe-
troleum products are considered as such; however, further
research of applicable California documents may be necessary
.. for a complete definition.
In addition to requiring secondary containment and monitor-
ing for the buried fuel storage tanks, consideration must be
�` given to the aboveground storage of other substances. The
chemical additives stored on the Stoneway site should be
considered as hazardous to the aquifer unless proven other-
+� wise. Double-walled tanks or containment dikes with an
impervious ground cover should be incorporated. The imper-
vious ground cover method would require that additional
i,,,,, consideration be given to drainage and/or treatment of pre-
cipitation runoff.
�
Brick Plant
The fuel storage facilities at the North American Refrac-
tories brick plant are not considered to be a major threat
+� to Renton' s aquifer because of the brick plant' s location on
the south side of the Cedar River. However, the ordinance
requirements outlined above for the service stations and the
,� concrete plant should also apply to this facility if suffi-
cient evidence developed to indicate that contaminants from
the brick plant could migrate to the aquifer.
�"" The chemicals stored on this site are commonly used in pot-
able water treatment processes , and therefore specific stor-
age requirements to protect the aquifer are not necessary.
�r.
Sanitary Sewers
Relocation of the 42-inch Metro sewer line away from the
i'" well field would reduce the contamination hazard. Recon-
struction of the pipeline with newer materials that would be
less likely to fail or leak would also reduce the risk of
� potential contamination. However, the present contamination
risk that the sewer line poses does not justify the large
expense of either of these options.
�
Awareness of the pipeline location and its potential impact
on the aquifer will allow the City to be alert for early
signs of sewer line failure. Needless to say, if such a
""' failure occurs, immediate response will be critical in pro-
tecting the aquifer from contamination.
ar
4-15
w�..
Continued bacteriological testing of raw water from the
wells represents the most cost-effective monitoring of this
potential contaminant source. Pressure testing of the pipe- �.
line to isolate leaks would be nearly impossible while main-
taining sewage flows.
Monitoring groundwater quality along the pipeline in the �
aquifer area would not be beneficial unless specific leak
locations had been identified. The water table is approxi-
mately 20 feet below ground while the pipeline is only 10
feet below ground. Although small 2-inch-diameter sampling
probes could be placed at intervals along the pipeline, the
6 ,000-foot length of pipeline through the aquifer area makes
this impractical.
If leaks are found within a limited length of pipeline, the
sewer should be repaired, or it could be lined with a PVC
insert. Lining of the Metro sewer with an insert for the
full 6,000 feet within the aquifer area should be considered
in the future as the pipeline ages and becomes more prone to �
leakage.
Most of what has been discussed above for the 42-inch Metro
sewer is also applicable to the 6-inch to 15-inch City of
Renton sanitary sewers in the aquifer area. The age, condi-
tion, depth above or below water table, and other details of
these sewers are unknown. Known leaks should be repaired. �
Other options for checking existing sanitary sewers for
leakage include TV inspection and smoke testing. Generally, ��
TV inspection will not disclose leaks in the pipe or joints �
unless the sewer is below the water table and infiltration
into the pipe can be observed. However, major structural --�,
damage (cracked or broken pipe) could be observed by TV in-
spection. Smoke testing will disclose leaks in sewers only
if the sewers are above the water table and the soil is po-
rous (gravelly or sandy) and relatively dry (no precipita- �
tion for some time) .
The abandoned sanitary sewers from the government housing
complex in Cedar River Park should be completely plugged.
Unplugged, these sewers will serve as conduits toward the
aquifer of any contaminants or surface water entering the
sewers at other points. These abandoned sewers should be
plugged at all possible locations, if this has not already
been done.
�.
Storm Sewers
Major leaks in storm sewers in the aquifer area should be -
located and repaired. Methods of leak detection are similar
to those discussed for sanitary sewers, except that pressure
testing could also be done easily when flows are nonexistent �.-0:�
4-16
wrr
,,,,,� or can be interrupted. Monitoring for storm sewer leaks in
the aquifer area by water quality sampling adjacent to the
storm sewers is not practical.
`"'"` Storm sewage, once collected into storm sewers, should be
piped to a river discharge point downstream of Renton' s aq-
uifer (as defined in Chapter 2) whenever possible. In par-
� ticular, any dry wells (sumps into which storm sewers empty)
in the aquifer area, whether serving public storm sewers or
private parking lots, should be eliminated by piping to other
,,,,r storm sewers.
Contaminants should be prevented from entering storm sewers
whenever possible. Oil traps at service stations, for exam-
�"' ple, should be inspected periodically by the City to ensure
good working order. Even frequent sweeping of streets is
effective in reducing contamination of stormwater flow. In
� specific cases, connection of a storm sewer source to the
sanitary sewer to provide treatment of the flow might be
more desirable than continuing to pipe the source to the
� storm sewer and ultimately the river. Separate treatment of
storm sewage by oil skimming and sedimentation in a deten-
tion pond is not considered feasible, except possibly in the
case of runoff from I-405, discussed later in this chapter.
�rw
There are few if any storm sewers on the plateau area (pri-
marily lower Maplewood) north of the Cedar River. Permeable
„�„ soils in this area allow percolation into the ground of run-
off from streets. Future land use in this area is expected
to be primarily residential. Served with sanitary sewers ,
such residential use is not expected to be a major source of
�" potential contaminants. Therefore, it is believed that the
stormwater runoff disposal by percolation into the ground
will continue to be acceptable as the area develops, and
+W+ that construction of an extensive storm sewer system is not
essential to protection of the City' s aquifer.
�,,,, Besides saving the cost of storm sewer construction, what-
ever natural recharge of the aquifer occurs from this source
will be beneficial. At this time there is no evidence that
the contaminants originating from residential sources in the
�"" area would not be attenuated satisfactorily in the subsoils.
If future water quality monitoring near the river narrows
indicates that storm water percolation here is endangering
+r�. the river water quality, and if water table elevation mon-
itoring at the aquifer indicates movement of water from the
river to the wells, then the need for storm sewers in this
� area should be reconsidered.
ir.
�
4-17
..
�
Cemetery Sites
The contamination risk associated with the existing cemetery
sites is believed to be minimal because of the small quantity
and probable attenuation of contaminants that may leach from
those sites. Relocation of the cemeteries to eliminate
these sources of potential contamination is not feasible. �
It is understood that current burial practices at both these
sites include the use of concrete vaults to prevent the
ground from collapsing around excavations. These vaults
also provide a means for containing potential contaminants.
Water quality analysis data from the City' s wells indicate �
that the levels of contaminants thought to be associated
with the cemetery sites are below the DSHS maximum contami-
nant levels. Monitoring trends of both primary and secon- �
dary chemical and physical contaminants at the wells would
indicate if the levels of these contaminants are increasing.
The City may wish to perform additional water quality tests ��
on water samples obtained closer to the cemeteries to deter- �
mine if the level of groundwater contaminants increases
nearer the sites. This information may be useful in ,�
determining if additional remedial actions , such as more �
stringent burial practices, are necessary.
Private Fill Sites �`�
�I
The possibility of harmful wastes being improperly disposed
at the three fill sites cited in Chapter 3 is a serious con- �,
cern. It is recommended that of these fill oper_�rions be �
controlled so that the City is assured trzt r�o materials
containing soluble poisons, paints, cleaners, waste oils , or
other leachable compounds , are incorporated into these �
fills. The fill operators should be bonded and be made
responsible for monthly reporting to the City of materials
incorporated into the fill, results of leachate monitoring, �
and for costs of subsequent cleanup if required. It is alsc
recommended that the City perform periodic spot checks of
these sites to enforce ordinance and permit requirements . �
SURFACE SOURCE PREVENTION
As discussed in Chapter 3 , contaminant sources that are or- �
ganized into the surface source category in this report are �i
limited to sprays and fertilizers. Urban runoff and acci-
dental spills are also specific types of surface sources.
However, prevention techniques related to these types of
surface sources are detailed in the Transportation Source
Prevention section of this chapter.
;�
4-18
�
irr
,r, SPrays and Fertilizers
The use of pesticides, herbicides, and fertilizers by pri-
vate parties is not believed to be a major threat to the
'�" aquifer because of the limited quantities that may be in-
volved. The EPA and the Department of Agriculture generally
regulate the use of these products. Many of the existing
�rr regulations are intended to protect the environment includ-
ing groundwaters. Imposing and enforcing additional r.e-
strictions on the general public v:ould probably not be cast
� effective or feasible.
Because the wells are located within City parks, the City
has direct control over the use of sprays and fertilizers in
�" the immediate area surrounding the wells. Limiting the use
of sprays and fertilizers within the City parks and other
public areas near the wells is the most effective means of
,w„ protecting against these sources of contamination. Mechani-
cal methods of weed and brush control are recommended in-
stead of chemicals near the well buildings.
�"' It is not recommended that the use of fertilizers in the
Parks be discontinued altogether; however, some products may
have less impact on water quality than others. Products
�.+ that are nearly insoluble in water should not be used.
These products are not readily decomposed or broken down and
therefore will tend to accumulate in the underlying soils
� with repeated dosages.
It is recommended that a park maintenance procedure management
plan be developed. This plan should identify chemicals that
�"' should or should not be used within the parks . The plan
should also include records of when chemicals are used and
the quantities involved. The types of shrubs and trees used
,r,,, for future landscaping within the parks and along the freeway
should also be considered in the plan. Some varieties of
plants require less maintenance with chemicals than others.
� WSDOT indicates that they have a list of sensitive areas
where they avoid using sprays. The area adjacent to the
well field is not currently on this list. The City should
+� request that spraying along the right-of-way near the wells
be discontinued or limited. WSDOT may in turn require an
agreement with the City which would delegate any necessary
�,,, mechanical maintenance work to the City. It is recommended
that the City contact WSDOT regarding this matter.
Burlington Northern does not have a listing of areas that
"�" may be sensitive to sprays. According to a Burlington
Northern representative, they contract out their right-of-
way brush maintenance with spraying contractors. The con-
w tractors are licensed by the U.S. Department of Agriculture.
It is the responsibility of the contractor to research sen-
sitive areas and take the necessary precautions.
�r.
4-19
�
The City should go on record by sending a letter to Burling-
ton Northern explaining the importance and sensitivity of
the well field area, and the consequences of contamination.
The City should request that Burlington Northern avoid the
use of chemical sprays near the well field.
TRANSPORTATION SOURCE PREVENTION �
Interstate 405
It is recommended that surface runoff from all paved areas
of I-405 which drain toward the aquifer be collected in
storm sewers and piped to the river downstream of the aqui-
fer. The existing catch basins at the I-405/SR 169 inter-
change are presently connected to the 30-inch storm sewer.
Where surface drainage now flows across unpaved shoulders,
as is the case under the elevated structure at the inter-
change, these shoulders should be paved to limit infiltra-
tion into the ground. Drainage from the elevated structure
and roadway to the north of the interchange should be piped �
to the storm sewer. The 30-inch storm sewer should be ex-
tended downriver beyond Wells 1 and 2. The distance down-
river should be determined by monitoring water table
elevations as discussed previously in this chapter. Al1
drainage from the elevated structure downspouts above the
river and south of the river should be collected in a storm
sewer and piped downstream as well. '�
�
Additional consideration should be given to separation of
I-405 storm sewage from other storm sewage in the 30-inch �
sewer. This would facilitate separation of oils and pos- �
sibly other contaminants from I-405 storm sewage in a deten-
tion basin prior to discharge to the river. The costs and
difficulties of successfully operating such separation fa-
cilities are recognized. The facilities would, however, be
useful in containing an accidental spill from I-405 and pre-
venting contamination of the river and Lake Washington. Any '�
separation facility should be sized appropriately to contain �
a large tanker truck spill.
Another alternative that should be considered further is
discharge of I-405 storm sewage to a sanitary sewer for
treatment. The risk of receiving explosive materials is
recognized, however. �
Construction of jersey barriers or similar walls with gut-
ters along the edges of all traffic lanes or paved shoul-
ders, including the on- and off-ramps, is recommended to
prevent vehicles from spilling contaminants down the pervi-
ous side slopes toward the aquifer. These barriers would �.
also protect the Well 8 and 9 buildings from impact by out- �
of-control vehicles from I-405.
��
4-20 ,�
�
i�r
,,,,,, Other means of containing spills could include covering the
slopes beyond the paved shoulders with an impervious material
to prevent infiltration of potential contaminants into the
ground. A polyethylene or plastic sheet material covered
"" with topsoil was considered, but suitable anchorage of the
topsoil mass may be difficult. Asphalt paving on the slopes
would also provide an effective protection against contami-
� nant infiltration but would not present an attractive ap-
pearance. Construction of the barriers described above,
while continuing the present grassed and planted surfacing
,�„ on the side slopes, appears to be the best alternative.
A paved trough or invert should be constructed at the toe of
the slopes to divert surface runoff and any spilled materials
''�" to the storm sewer system and away from the well field.
Toward this end, the City is including certain site work in
the construction package for the Well 9 pump building. This
�r+ site work will provide an access road to the pump building
around the north corner of the park. The road will be
slightly elevated above the surrounding grade of the park to
� act as a barrier to surface runoff from the I-405 embankment
and SR 169. All runoff on the I-405/SR 169 side of the ac-
cess road will be directed to catch basins and storm sewers
away from the well field.
�r.
The proposed freeway improvements for I-405 should include
all of the above features to protect the well field from
�,,, traffic-related contamination.
Special consideration should be given to the protection of
the well field during construction of I-405 improvements.
�` Construction activities will disturb the vegetation and other
existing protection features such as gutters and storm sewer
connections. Contaminated runoff material may be more fre-
+� quently discharged into the soils above the aquifer. Con-
struction equipment refueling, oil changing, and lubrication
should be done within containment areas away from the well
� field.
The City of Renton should be actively involved in alterna-
tive evaluations and design decisions for I-405 improvements
`�" that relate to well field protection. Protection of the
well field should be specifically addressed in the environ-
mental impact statement being prepared by WSDOT for these
�. improvements.
SR 169 (Maple Valley Highway)
� The use of jersey barriers with gutters along the north and
south paved shoulders of SR 169 from the I-405 interchange
east to the bedrock narrows is recommended wherever possi-
� ble. This will control runoff from the paved roadway and
limit the spread of contaminants from an accidental spill.
All roadway runoff should be collected into storm sewers and
�,,,, discharged to the river downstream of Wells 1 and 2 .
4-21
w.
�
although not as effective, discharge of this storm sewage to �
the river upstream of Wells 1 and 2 is preferable to not
containing and collecting the runoff at all, as is presently �
done. Another alternative, also not as effective, would be
to contour the ground along the south side of SR 169 with a
paved shoulder and ditch invert near the south right-of-way ��
line. All runoff from the roadway, including that piped �
from the north side of the road, could be collected in the
paved ditch and piped to the river. Accidental spills be-
yond the paved ditch might still occur. �
Limitations on materials hauled by truck traffic on SR 169
may be impractical since SR 169 is the major traffic arte- �
rial east of Renton. Additional safeguards in the manner in
which these materials are hauled (the solid waste transfer
trucks, for example) might be implemented to prevent or re-
duce the chances of spillage. �
City Streets
One method of preventing potentially hazardous spills from �
occurring on City streets around the well field would be to
limit commercial truck traffic. This would limit the number
of vehicles hauling large quantities of potential contami-
nants through the area. Service stations adjacent to the
wells require periodic bulk shipments of petroleum products.
Use of these streets would still be necessary for these lo- �
cal deliveries, as long as these businesses remain in the
area. However, through truck traffic should be rerouted
where feasible. The City should restrict the types of �
materials hauled by commercial truck traffic in the area �
around the wells. We understand that the City' s Public
Works Director has the authority to establish such traffic
restrictions although there is no City leqislation of record
regarding this matter.
WSDOT has indicated that no additional on- and off-ramps are �
included in the planned improvements for I-405. Traffic
patterns on City streets adjacent to the aquifer are related
to existing I-405 access. These patterns cannot be changed �
because alternative traffic routes do not exist. Total re- �
striction of truck traffic on these streets may severely
disrupt commercial activity in the adjacent area.
The best alternative for prevention of contamination from
the City streets appears to be that of collecting all sur-
face runoff (storm sewage) and contaminant spills to the
extent possible. Street surfaces should be kept in good
repair and shoulder areas where necessary should be paved to
prevent or limit infiltration of materials from the surface.
All runoff should be piped to the river, downstream of
Wells 1 and 2 whenever possible.

rr
�r• Rai lroad
Due to the relatively slow speed of trains traveling within
�, the city limits and the limited use of the tracks near the
wells, the probability of a major rail accident affecting
water quality is low.
'�" The City should express a concern directly to Burlington
Northern regarding spillage of materials. The company may be
able to take special precautions to protect the well field,
�„ such as making sure that tracks are properly maintained. As
discussed previously in the Emergency Response Plan section
of this chapter, awareness of the sensitivity of the area
� may also improve the response of Burlington Northern and
others should an accidental spill occur.
It is possible that the tracks paralleling the Cedar River
+�■+ on the south bank may be abandoned by Burlington Northern in
the future. According to a Burlington Northern representa-
tive, this matter is being studied but a final decision re-
�,,, garding abandonment is not expected in the near future. The
City should stay abreast of any information regarding this
potential abandonment. Future acquisition of this right-
of-way by the City would provide direct control over its
`�" use. With direct ownership, the City could establish a rec-
reation greenbelt along the south bank of the river to mini-
mize the exposure of the wells from potential contaminating
�. activities.
GENERAL SOURCE PREVENTION
+�r
Coal Mines
As stated in Chapter 3 , there are many unknowns associated
"' with the possible use of abandoned coal mines as waste dis-
posal sites. Some of these unknowns include the location
and number of sites that may be involved, and the types and
�,. quantities of substances being disposed. The risk associ-
ated with these sites is believed to be low. Therefore,
aside from being aware that these potential contaminant
sources may exist, no specific actions by the City are
� recommended.
Residential Heatinq Oil Tanks
1�r
The contamination risk associated with residential heating
oil tanks is believed to be low, however, the City may wish
�„ to conduct a survey of the residences in the aquifer re-
charge area to determine the location, capacity, and age of
buried heating oil and private motor fuel storage tanks.

The risks associated with the leakage from tanks found within
the area could then be evaluated, and a program for prevent-
ing contamination from this source could be developed if
necessary.
Residential Use and Disposal ;�
It is recommended that the City sponsor or actively partici- �
pate in an education program to inform the public of the
potential consequences of continued disposal of materials
such as paints, waste oils, insecticides , pesticides, and
poisons at the landfill sites, residential sites, or other
unapproved locations. The public should be informed of the
locations where these materials can be disposed of in a
proper manner. Continued dumping of potential contaminants
into the landfills may cause future water quality problems
for the City. The program could include special educational
inserts to be sent with monthly garbage collection, sewer,
or water billings.
The City could also establish convenient collection centers
for the public to drop off materials that are undesirable at
transfer stations or landfills. This would help eliminate
the illegal dumping of these materials onto the ground or
into the storm sewer catch basins.
Dry Cleaners
The disposal practices of any dry cleaning businesses located
within the aquifer recharge area should be monitored to deter- �
mine if additional safeguards are necessary. ThesP safe- �
guards may include more stringent enforcement of existing
regulations or the enactment of additional controls to set �
greater penalties for improper disposal of chemical solvents. �
CONCLUSIONS
Potential contaminant sources have been identified from in- �
formation furnished by the City and from supplementary
sources where possible. Methods of contamination prevention
have been discussed and recommendations made in specific
cases, particularly for those sources of potential contamin-
ation believed to be of greatest threat to aquifer water
quality.
No guarantee is made that all existing contaminant sources
have been identified. Additional contaminant sources may be
identified in the future, as well as additional or improved
methods of contamination prevention.
The City of Renton, with the help of DSHS, DOE, WSDOT, Metro,
and other agencies, should implement the recommended contami-
nation prevention measures as soon as feasible to protect
the existing high quality of Renton' s Cedar River aquifer. �
4-24
�
�r �
+� Progress toward implementation of these measures should be
reviewed after one year to determine whether the City is in
fact staying ahead of the potential contamination problem.
�
One option to protection of the existing well field which
the City should consider is that of relocating the City' s
wells upriver. The Renton Parks Department has considered
�"" purchase of the Maplewood Golf Course. The Golf course,
together with the King County Park Department land and other
sparsely populated lands for several miles upstream of the
�.r Golf Course could provide Renton with an aquifer which is
better protected than the existing well field area. However,
several major questions must be resolved prior to such a
� move. These include:
o Is the aquifer in the Cedar River Valley near the
Maplewood Golf Course suitable for development of
�" major wells which could supply Renton' s water
needs?
,y,,,, o Are the water rights presently held at the exist-
ing well field transferrable to the new location?
o Is the groundwater quality in this area suitable
�" for municipal supply without treatment, except
chlorination?
�+ o Could all of the property in the valley necessary
for protection of the new aquifer be obtained, or
the land use thereon controlled? Land use up the
,�, valley might be controlled, for example , by pur-
chase of development rights through the King County
Farmlands Preservation Act.
""' o Would the cost of drilling new wells, constructing
new pump buildings and chlorination facilities,
and constructing a major transmission line into
� Renton be justified?
o Could such a relocation (aside from constructing
� the transmission line) be done one well at a time
to minimize near-term expenditure?
o Could the ownership of lands, or rights to locate
'� wells in the area, and protection of the area from
contamination, be secured now to allow relocation
of City wells in the future?
�
As first steps toward the goal of eventual relocation of
wells, the City should initiate a separate study to consider
�w.
the following:
�
4-25
�
�
o Explore the aquifer area to determine its geologic �
and hydrologic value as a municipal water source.
Such exploration might include the drilling of
several test wells, which could be capped for fu-
ture use. Such exploration should also determine
water quality. �
o Purchase the Maplewood Golf Course, or establish
an option to purchase it, or obtain permission to
drill exploratory or permanent wells on it.
o Investigate the other questions posed above to
determine whether relocation of the wells is eco-
nomically and politically feasible.

Theoretically, a slightly positive index should be non-corrosive, while an increasing negative index indicates increasing
corrosivity. Locally, waters with an Index of less than -1.0 are considered to be non-corrosive. A reading of greater
than -2.0 should be considered highly corrosive.

r,r Subject: Renton Well Field Protection Study
Effects of I-405 on Wells and Water Quality
� Art Storbo started the meeting by describing the study which
CH2M HILL is currently conducting. The study is to identify
the well field recharge area, identify potential well field
contaminant sources, and recommend ways of preventing con-
�► tamination of the well field. The purpose of the meeting
was to specifically address the impact Interstate 405 cur-
rently has or may have in the future on the well field.
� Accidental spills of chemicals and petroleum products from
the freeway was labeled as the major concern. Normal surface
runoff carrying oils and other contaminants was also addressed.
Physical impact from out of control vehicles, although not
'�"' on the subject of contamination, was also mentioned as being
a concern.
r.. The significance of the well field to the City was stressed.
The five wells adjacent to the freeway produce approximately
85 percent of the City' s total water supply. Art described
� the aquifer and sources of recharge. In addition to recharge
from the river, surface water from the area surrounding the
well field infiltrates through the soils to recharge the
aquifer. It was also mentioned that the City does not have
"' other comparable sources of water available to them.
CH2M HILL is currently designing the pump station for Well
,,., No. 9 and anticipates incorporating possible improvements in
that construction project to prevent contamination from I-405.
Dale Wirkkala described the status of the I-405 expansion
"�`' project and briefly outlined what the project will include.
There are currently 12 different alternatives that WSDOT is
,�.
w.r
considering to add High Occupancy Vehicle (HOV) lanes to the
I-405 corridor. Basically the alternatives are:
o Widen the existing S-Curve structure
o Relocate the alignment to the east of the existing
roadway
o Relocate to the west of the existing roadway
Included in each of these alternatives are various vertical
alignment alternatives. Alignments relocated to the west or
east might conflict with existing well locations. The option �.
of doing nothing at all was also mentioned as a possibility.
WSDOT has an open house scheduled for April 25, 1984 to discuss
these alternatives with the public. It is hoped that after
the open house some of the options can be eliminated. Dale
pointed out that it is possible that additional alternatives
may be suggested by the public. An environmental impact
statement (EIS) is being prepared by WSDOT for the area of
the freeway from the South Renton interchange to Sunset Bl.vd.
The draft EIS is scheduled to be completed by October or
November of 1984. Advertisement for construction is scheduled
for 1987.
Bob Bergstrom brought up the subject of hauling hazardous
materials on I-405 through the Renton area. The City is
concerned that hauling these types of material through the
I-90 tunnels may be banned in the future thus increasing the
volume of this kind of traffic through Renton. The WSDOT
representatives at this meeting stated that they are not
directly involved with the I-90 corridor and were therefore
unable to provide input on this subject. Harold Morgan stated
that he would discuss the issue with others at the DOT to
find out what plans were being considered for I-90 and get
comments back to the City. The City verbally requested to
be involved in the planning process on regional issues such
as this that may directly impact the City. The City is also
concerned about solid waste hauling decisions that are being
made by others that may directly impact the groundwater quality
in the well field area. The City of Seattle, King County,
and Snohomish County are all considering hauling all of their
garbage to the Cedar Hills landfill east of Renton. It is
estimated that 150 transfer station container trucks could
pass through the Maple Valley interchange at I-405 each day.
Control of freeway surface drainage was discussed in detail.
The WSDOT representatives thought that Jersey barriers could
be incorporated into the freeway design along the shoulder
to divert drainage to the freeway storm drain system. They
indicated that they would look at the area after the meeting
to determine if interim barriers could be used to divert
runoff to the existing storm drain system.
y.
,w, It was pointed out that due to Interstate funding require-
ments, the City should submit a formal request for any im-
provements the City may wish WSDOT to consider. The City
indicated that WSDOT can expect a letter in the future from
� them.
WSDOT anticipates resurfacing I-405 through Renton this summer.
�r• Bob Bergstrom pointed out that last time this was done the
tack coat ran into the storm drain system and polluted the
Cedar River. WSDOT will address this concern to prevent a
�, similar incident.
The location of the northbound exit to Highway 169 with respect
to Well No. 9 is a concern of DSHS. Redesign of exits and
""" on-ramps is not anticipated. The City will include this
issue in their letter to WSDOT. Collection of surface runoff
from the interchange is a major concern.
�.
The possibility of declaring the well field as a sole source
of water supply was discussed. Bob McCormick thought that
� this may cause federal funding problems for the City on
other projects. The issue was discussed to consider whether
such a declaration could force WSDOT to make certain freeway
improvements or possibly imposing traffic restrictions on
� types of materials hauled through the area.
WSDOT requested a copy of the draft Well Field Protection
�„�„ Study Report when it is complete. It was agreed that the
City would provide a copy to them.

SUBJECT: Protection of Renton Cedar River Aquifer from Potential
Contamination Related to interstate-405
�
Gentlemen :
This letter is written as a followup to our meeting of March 20 , 1984 ,
""" at Renton City Hall , In that meeting , aiso attended by
representatives of DSHS, DOE , and CH2m Hill , We discussed the
following :
�
Background and purpose of our current Well Field
Protection Study
�` WSDOT plans and schedule for improvements to I -405
Ways to prevent potential contamination of the well
�'"' field from I -405 sources
The City of Renton depends upon the Cedar Rlver aquifer adJacent to
� I -405 for aimost 85 (eighty-five) percent of its potable water
supply. No comparable sources of potable water are available . The
Ctty has for many years enJoyed high-quality water trom this source .
However, it has recently been recognized that the Cedar River aquifer
"' is vulnerable to contamination from many sources . One of the
principal sources is I -405 .
«.� The City of Renton intends to protect and preserve existing water
quality in the aquifer . it is our wish to be actively involved in
regional decisions regarding transportation of hazardous materials on
�, 1 -405, State Route ( 69, and related state highways . This would
include assessment of impact on I -405 tratftc caused by a proposed ban
on transportation of hazardous materials through the I -90 tunnels west
of Lake Washington .
�
The City hereby requests that WSDOT carefuliy consider the tollowing
items in developing plans for improvements (expansion and realignment)
,�, of I -405 through Renton from South Renton to Sunset Boulevard .
.�►
�
-2-
Siting of I -405 and on-/off-ramps relative to exist-
ing weil field facilities
Containment of all surface runoff including that from
accidentai spiils
An oil/containment trap in the storm sewer between I -405
and the discharge to the Cedar River
Location of the discharge point downriver from the well
field
impact barriers ( fersey barrters or other means) along
the soutside freeway lanes and on-loff-ramps to prevent
accidental spiils beyond the pavement Itmits and to
prevent physical damage to well field buildings from
out-of-controi vehicles
Paving of shoulder areas and coilection of surface runoft
beyond the paved areas within the right-of-way
�
The City wouid like to be involved in evaluation of alternatives
related to the above items . We request that protection of the well
field and aquifer be speciflcally addressed in the Environmental �
Impact Statement currentiy being prepared by WSDOT .
The City also requests that the foliowing interlm improvements be
implemented by WSDOT prior to the planned expansion of I -405 in 1987 :
Jersey barriers along the east shoulder of I -405
from the north end of the S-curve structure to the
bottom of the northbound offramp at SR169 to protect
Welis 8 and 9 from impact and to direct surface runoff
to existing WSDOT storm drains
P� pirg cf sjorm ; laws in Itau of continued use of
overland (surface) ditches such as that observed
in the northeast corner ot the I -405/SR169 Inter-
change to prevent infiltration ot contaminated
storm water
Asphalt surfacing of runoff areas such as the
gravel ( dirt) shoulders under the overpass at
SR169 to prevent infiitration of contaminated
Installation of a piped coliection system on the
existing downspouts from the elevated structure �
over and south of the Cedar River , to dlscharge to
the river , preferably downstream of Wells I and 2
storm water
