HomeMy WebLinkAbout120924 Dickinson Submittal Audience CommentOn September 24, a federal judge ordered EPA to take regulatory action to eliminate the
"unreasonable risk" to the health of children posed by the practice of water fluoridation. The
plaintiffs argued that fluoride poses risks to human health, particularly neurodevelopmental
harm in children. The court found that the EPA had failed to adequately address these
concerns under the Toxic Substances Control Act (TSCA). As a result, EPA will either appeal
the decision or revisit its fluoride risk assessment. More information can be found here.
Possible Consequences of Court Ruling on Safety of Water Fluoridation
Lilian White, MD
Posted on October 21, 2024
Fluoride has been added to drinking water in various regions of the United States since 1945
for the purpose of preventing tooth decay. Currently, concern arises for the negative health
effects of a chemical, individuals may petition the Environmental and Protection Agency (EPA)
to act. If the petitioner disagrees with the EPA's assessment, they may go to court for another
opinion.
The practice of supplementing drinking water with fluoride has come under scrutiny recently
when a court ruling on September 27, 2024, declared the currently recommended water level
of fluoridation in the United States (0.7 mg per L) an unreasonable risk to health. Under
the Toxic Substances Control Act, the EPA is now compelled to respond through regulatory
action such as banning fluoridation or simply requiring a warning label on fluoridated water;
however, the specific regulatory action is left to the EPA's discretion.
Organizations such as the American Dental Association and American Academy of
Pediatrics have voiced opposition to the ruling and continue to stand by recommendations for
widespread drinking water fluoridation. In 1999, the Centers for Disease Control and
Prevention (CDC) noted water fluoridation to be one of the top 10 great public health
Achievements of the 20th Century, making a reversal of this accomplishment particularly
controversial among some public health advocates. The AAFP has not commented on the
case, but its current policy is in support of water fluoridation.
A systematic review conducted by the National Toxicology Program of the U.S. Department of
Health and Human Services reported a 1-point drop in the IQ of children per 0.28 mg per L of
fluoride in a pregnant mother's urine. This was similarly corroborated by a cohort study
published in JAMA earlier this year, raising concern for exposure to fluoridated water and
clinical neurobehavioral problems among children.
A meta -analysis conducted in 2024 assessing the effect of high -fluoride drinking water
exposure and thyroid health demonstrated an increase in the risk of thyroid diseases.
Additionally, excess fluoride exposure may cause dental fluorosis in children with developing
teeth (discoloration of teeth, among other adverse dental effects), which may be due to
excessive fluoride exposure or low-level exposure over time. Fluorosis is primarily a cosmetic
concern; however, as with other cosmetic diseases, it has the potential to negatively affect
the self-esteem of children.
Interestingly, the association between tooth mottling due to fluorosis (incidentally caused by
fluoride exposure) and reduced dental decay was the finding that eventually led to
the movement to fluoridate drinking water in the United States. By 1989. 70% of the U.S. had
fluoridated drinking water. Some states have even added water -fluoridation requirements to
their laws, and most states have some degree of drinking water fluoridation.
People in the United States are primarily exposed to fluoride through supplemented drinking
water, topical dental products, and foods and beverages to which fluoride has been added.
The CDC recommends a fluoride level of 0.7 mg per L of drinking water to prevent tooth
decay. The Community Preventive Services Task Force recommends fluoridation based on an
older systematic review.
Real -world epidemiologic studies on the cost:beneflt ratio of drinking water fluoridation are
lacking. It has been theoretically estimated that fluoridated drinking water may result in
savings of $32 per person per year with an estimated cost of $0.12 to $0.60 per person per
year. The cost of harm from fluoridated drinking water has yet to be studied outside of
theoretical models.
For patients concerned about their personal exposure to fluoridated drinking water, physicians
can direct patients to My Water's Fluoride, a CDC directory for local water fluoridation;
however, not all states participate in this program, and the directory does not provide
quantitative exposure measures. The Environmental Working Group's Tap Water
Database provides more detailed information on a large number of possible water
contaminants in addition to fluoride as well as information on specific filters that will remove
relevant chemicals, offering a more practical resource for patients.
It will be interesting to see how the EPA responds to this court order to address fluoridated
water as an unreasonable risk to health. With the current widespread use of fluoridated water,
any regulatory action will likely be slow to implement. Additional research is needed on
whether the potential adverse effects of fluoridation outweigh the established benefits for
preventing caries in children.

quality and safety - which fluoride does not do). This is one of the reasons why much of
Europe has rejected fluoridation.

The Phosphate Fertilizer
Industry: An Environmental
Overview
June 11, 2012 Fluoride Action Network
phosphate industry licofluorides
1. Introduction
They call them "wet scrubbers" - the pollution control devices ussed by the
phosphate industry to capture fluoride gases produced in the production of
commercial fertilizer.
In the past, when the industry let these gases escape, vegetation became
scorched, crops destroyed, and cattle crippled.
Today, with the development of sophisticated air -pollution control technology, less
of the fluoride escapes into the atmosphere, and the type of pollution that
threatened the survival of some communities in the 1950s and 60s, is but a thing
of the past (at least in the US and other wealthy countries).
However, the impacts of the industryes fluoride emissions are still being felt,
although more subtly, by millions of people - people who, for the most part, do
not live anywhere near a phosphate plant.
That's because, after being captured in the scrubbers, the fluoride acid
(hydrofluorosilicic acid), a classified hazardous waste, is barreled up and sold,
unrefined, to communities across the country. Communities add hydrofluorosilicic
acid to their water supplies as the primary fluoride chemical for water fluoridation.
Even if you don't live in a community where fluoride is added to water, you'll still
be getting a dose of it through cereal, soda, juice, beer and any
other processed food and drink manufactured with fluoridated water.
Meanwhile, if the phosphate industry has its way, it may soon be distributing
another of its by-products to communities across the country. That waste product
is radium, which may soon be added to a roadbed near you - if the EPA buckles
and industry has its way.
2. Effects of Fluoride Pollution
Central Florida knows it well. So too does Garrison Montana, Cubatao Brazil, and
any other community where phosphate industries have had inefficient, or non-
existent, pollution control: Fluoride.
The Canadian Broadcasting Corporation (CBC) called the phosphate industry a
"pandora's box." While the industry brought wealth to rural communities, it also
brought ecological devastation. The CBC described the effects of one particular
phosphate plant in Dunville, Ontario:
"Farmers noticed it first... Something mysterious burned the peppers, burned the
fruit, dwarfed and shriveled the grains, damaged everything that grew. Something
in the air destroyed the crops. Anyone could see it... They noticed it first in 1961.
Again in '62. Worse each year. Plants that didn't burn, were dwarfed. Grain yields
cut in half... Finally, a greater disaster revealed the source of the trouble. A plume
from a silver stack, once the symbol of Dunville's progress, spreading for miles
around poison - fluorine. It was identified by veterinarians. There was no doubt.
What happened to the cattle was unmistakable, and it broke the farmer's hearts.
Fluorosis - swollen joints, falling teeth, pain until cattle lie down and die. Hundreds
of them. The cause - fluorine poisoning from the air."
Fluoride has been, and remains to this day, one of the largest
environmental liabilities of the phosphate industry. The source ot` the problem lies
in the fact that raw phosphate ore contains high concentrations of fluoride,
usually between 20,000 to 40,000 parts per million (equivalent to 2 to 4% of the
ore).
When this ore is processed into water-soluble phosphate (via the addition of
sulfuric acid), the fluoride content of the ore is vaporized into the air, forming
highly toxic gaseous compounds (hydrogen fluoride and silicon tetrafluoride).
In the past, when the industry had little, if any, pollution control, the fluoride gases were
frequently emitted in large volumes into surrounding communities, cdusing serious
environmental damage.
In Polk County, Florida, the creation of multiple phosphate plants in the 1940s
caused damage to nearly 25,000 acres of citrus groves and "mass fluoride
poisoning" of cattle. It is estimated that, as a result of fluoride contamination, "the
cattle population of Polk County dropped 30,000 head" between 1953 and 1960,
and "an estimated 150,000 acres of cattle land were abandoned" (Linton
1970). According to the former president of the Polk County Cattlemen's
Association:
"Around 1953 we noticed a change in our cattle... We watched our cattle become
gaunt and starved, their legs became deformed; they lost their teeth.
Reproduction fell off and when a cow did have a calf, it was also affected by this
malady or was a stillborn."
In the 1960s, air pollution emitted by another phosphate plant in Garrison,
Montana was severe enough to be branded "the worst in the nation" by a 1967
National Air Pollution Conference in Washington, D.C.
As in Polk County, and other communities downwind of fluoride emissions, the
cattle in Garrison were poisoned by fluoride. As described in a 1969 article from
Good Housekeeping:
"The blight had afflicted cattle too. Some lay in the pasture, barely able to move.
Others limped and staggered on swollen legs, or painfully sank down and tried to
graze on their knees... Ingested day after day, the excessive fluoride had caused
tooth and bone disease in the cattle, so that they could not tolerate the anguish of
standing or walking. Even eating or drinking was an agony. Their ultimate fate was
dehydration, starvation - and death."
3. Litigation from Fluoride Damage
Damage to vegetation and livestock, caused by fluoride emissions from large
industry, has resulted, as one might expect, in a great deal of expensive litigation.
In 1983, Dr. Leonard Weinstein of Cornell University, stated that "certainly, there
has been more litigation on alleged damage to agriculture by fluoride than all
other pollutants combined" (Weinstein 1983). While Weinstein was referring to
fluoride pollution in general, his comments give an indication of the problem
facing the phosphate industry - one of the most notorious emitters of fluoride - in
its early days.
So too does an estimate from Dr. Edward Groth, currently a Senior Scientist at
Consumers Union. According to an article written by Groth, fluoride pollution
between the years 1957 to 1968, "was responsible for more damage claims
against industry than all twenty (nationally monitored air pollutants) combined."
The primary reason for the litigation against fluoride emitters was "the painful,
economically disastrous, debilitating disease" that fluoride causes to livestock
(Hodge & Smith 1977). As noted in a 1970 review by the US Department of
Agriculture (USDA),
"Airborne fluorides have caused more worldwide damage to domestic animals
than any other air pollutant" (Lillie 1970).
Another review on air pollution reached the same conclusion. According to Ender
(1969):
"The most important problem concerning damage to animals by air pollution is, no
doubt, the poisoning of domestic animals caused by fluorine in smoke, gas, or
dust from various industries; industrial fluorosis in livestock is today a disorder
well known by veterinarians in all industrialized countries."
According to a review discussing "Fluorine toxicosis and industry", Shupe noted
that:
"Air pollution damage to agricultural production in the United States in 1967 was
estimated at $500,000,000. Fluoride damage to livestock and vegetation was a
substantial part of this amount" (Shupe 1970).
4. Scrubbing away the problem
Due to the inevitable liabilities that fluoride pollution presented, and to an
increasingly stringent set of environmental regulations, the phosphate industry
began cleaning up its act. As noted by Ervin Bellack, a chemist for the US Public
Health Service:
"In the manufacture of super -phosphate fertilizer, phosphate rock is acidulated
with sulfuric acid, and the fluoride content of the rock evolves as volatile
silicofluorides. In the past, much of this volatile material was verited to the
atmosphere, contributing heavily to pollution of the air and land surrounding the
manufacturing site. As awareness of the pollution problem increased, scrubbers
were added to strip particulate and gaseous components from the waste gas..."
(Bellack 1970)
A 1979 review, published in the journal Phosphorous & Potassium, added:
"The fluorine compounds liberated during the acidulation of phosphate rock are
now rightly regarded as a menace and the industry is now obliged to suppress
emissions -containing vapors to within very low limits in most parts of the world...
In the past, little attention was paid to the emission of gaseous fluorine
compounds in the fertilizer industry. But today fluorine recovery is increasingly
necessary because of stringent environmental restrictions which demand drastic
reductions in the quantities of volatile and toxic fluorine compounds emitted into
the waste gases. These compounds now have to be recovered and converted into
harmless by-products for disposal or, more desirably, into marketable products"
(Denzinger 1979).
5. A Missed Opportunity: Little Demand for Silicofluorides
Considering the great demand among big industry for fluoride chemicals as a
material used in a wide variety of commercial products and industrial processes,
the phosphate industry could have made quite a handsome profit selling its
fluoride wastes to industry. This was indeed the hope among some industry
analysts, including the authors of the review noted above (Denzinger 1979).
However, the US phosphate industry has thus far been unable to take advantage
of this market. The principal reason for this failure stems from the fact that
fluoride captured in the scrubbers is combined with silica. The resulting
silicofluoride complex has, in turn, proved difficult for the industry to separate and
purify in an economically -viable process.
As it now stands, silicofluoride complexes (hydrofluorosilicic acid & sodium
silicofluoride) are of little use to industry. Thus, while US industry continues to
satisfy its growing demand for high-grade fluoride chemicals by importing calcium
fluoride from abroad (primarily from Mexico, China, and South Africa), the
phosphate industry continues dumping large volumes of fluoride into the acidic
wastewater ponds that lie at the top of the mountainous waste piles which
surround the industry. In 1995, the Tampa Tribune summed up the situation as
follows:
"The U.S. demand for fluorine, which was 400,000 tons, is expected to jump 25
percent by next year... Even though 600,000 tons of fluorine are contained in the
20 million tons of phosphate rock mined in Florida, the fluorine market has been
inaccessible because the fluorine is tied up with silica, a hard, glassy material."
Of course, not all of the phosphate industry's fluoride waste is disposed of in the
ponds. As noted earlier, the phosphate industry has found at least one regular
consumer of its silicofluorides: municipal water -treatment facilities. According to
recent estimates, the phosphate industry sells approximately 200,000 tons of
silicofluorides (hydrofluorosilicic acid & sodium silicofluoride) to US communities
each year for use as a water fluoridation agent (Coplan & Masters 2001).
6. Fluoridation: "An ideal solution to a long-standing problem"?
In 1983, Rebecca Hanmer, the Deputy Assistant Administrator for Water at the US
Environmental Protection Agency, described the policy of using the phosphate
industry's silicofluorides for fluoridation as follows:
"In regard to the use of fluosilicic acid as the source of fluoride for fluoridation,
this agency regards such use as an ideal solution to a long standing problem. By
recovering by-product fluosilicic acid from fertilizer manufacturing, water and air
pollution are minimized, and water authorities have a low-cost source of fluoride
available to them." (See letter)
Another EPA official, Dr. J. William Hirzy, the current Senior Vice -President of EPA
Headquarters Union, recently expressed a different view on the matter. According
to H i rzy-
" If this stuff gets out into the air, it's a pollutant; if it gets into the river, it's a
pollutant; if it gets into the lake it's a pollutant; but if it goes right into your
drinking water system, it's not a pollutant. That's amazing... There's got to be a
better way to manage this stuff."
7. Recent Findings on Silicofluorides
Adding to Hirzy's, and the EPA Unions, concerns are three recent findings.
A tank of hydrofluosilicic acid (a form of silicofluoride) at water treatment plant.
First and foremost are two recent studies reporting a relationship between water treated
with silicofluorides and elevated levels of lead in children's blood (Masters & Coplan
1999, 2000). The authors of these studies speculate that the silicofluoride complex may
increase the uptake of lead (derived from other environmental sourcet, such as lead
paint) into the bloodstream.
The second finding is the recent, and quite
remarkable concession from the EPA, that despite 50 years of water
fluoridation, the EPA has no chronic health studies on silicofluorides.
All safety studies on fluoride to date have been conducted using
pharmaceutical -grade sodium fluoride, not industrial -grade
silicofluorides. A similar concession has also been obtained from the
respective authorities in England.
The defense made by agencies promoting water fluoridation, such as the US
Centers for Disease Control, to the lack of such studies, is that when the
silicofluoride complex is diluted into water, it dissociates into free fluoride ions or
other fluoride compounds (e.g. aluminum -fluoride), and thus the treated water,
when consumed, will have no remaining silicofluoride residues (Urbansky &
Schock, 2000).
This argument, while supported by a good deal of theoretical calculation is at odds
with a recently obtained and translated PhD dissertation from a German chemist.
(Westendorf 1975). According to the dissertation, not only do the silicofluorides
not fully dissociate, the remaining silicofluoride complexes could be more potent
inhibitors of cholinesterase, an enzyme vital to the functioning of the central
nervous system.
The third finding is that the silicofluorides, as obtained from the scrubbers of the
phosphate industry, contain a wide variety of impurities present in the process
water - particularly arsenic and possibly radionuclides. While these impurities
occur at low concentrations, especially after dilution into the water, their
purposeful addition to water supplies directly violates EPA public health goals. For
instance, the EPA's Maximum Contaminant Level Goal for arsenic, a known human
carcinogen, is 0 parts per billion. However, according to the National Sanitation
Foundation, the addition of silicofluorides to the water supply will add, on average,
about 0.1 to 0.43 ppb, and as much as 1.6 ppb, arsenic to the water.
As noted by the Salt Lake Tribune,
"Those who had visions of sterile white laboratories when they voted for fluoride
weren't thinking of fluorosilicic acid. Improbable as this sounds, much of it is
recovered from the scrubbing solution that scours toxins from smokestacks at
phosphate fertilizer plants."
8. Gypsum Stacks & 'Slime Ponds'
Fluoride -contaminated wastewater sitting on top of "gypsum stack."To make 1
pound of commercial fertilizer, the phosphate industry creates 5 pounds of
contaminated phosphogypsum slurry (calcium sulfate). This slurry is piped from
the processing facilities up into the acidic wastewater ponds that sit atop the
mountainous waste piles known as gypsum stacks.
According to the EPA, 32 million tons of new gypsum waste is created each year
by the phosphate industry in Central Florida alone. (Central Florida is the heart of
the US phosphate industry). The EPA estimates that the current stockpile of waste
in Central Florida's gypsum stacks has reached "nearly 1 billion metric tons." (The
average gypsum stack takes up about 135 acres of surface area - equal to about
100 football fields - and can go as high as 200 feet.)
9. Radiation Hazard
It is sort of a misnomer, however, to call these stacks "gypsum" stacks. Indeed, if
the stacks were simply gypsum, they probably wouldn't exist, as gypsum can be
readily sold for various purposes (e.g. as a building material). What can't be
readily sold, however, is radioactive gypsum, which is about the only type of
gypsum the phosphate industry has to offer.
The source of the gypsum's radioactivity is the presence of uranium, and
uranium's various decay products (i.e. radium), in raw, phosphate ore. As noted
by the Sarasota Herald Tribune
"there is a natural and unavoidable connection between phosphate mining and
radioactive material. It is because phosphate and uranium were laid down at the
same time and in the same place by the same geological processes millions of
years ago. They go together. Mine phosphate, you get uranium."
While uranium, and its decay -products, naturally occur in phosphate ore, their
concentrations in the gypsum waste, after the extraction of soluble phosphate, are up to
60 times greater.
The gypsum has therefore been classified as a "Naturally Occurring Radioactive
Material", or NORM waste, although some, including the EPA, have questioned
whether this classification understates the problem. According to the Tampa
Tribune, the gypsum "is among the most concentrated radioactive waste that
comes from natural materials."
It is so concentrated, in fact, that "it can't be dumped at the one landfill in the
country licensed to take only NORM waste."
Thus, according to US News & World Report, the EPA is currently "weighing
whether to classify the gypsum stacks as hazardous waste under federal statutes,
which would force the industry to provide strict safeguards" (to nearly 1 billion
tons of waste).
One of EPA's main concerns with gypsum stacks centers around the fact that
radium-226 breaks down into radon gas. When radon gas is formed, it can
become airborne, leading to potentially elevated exposures downwind of the
stacks. Such airborne exposures are of particular concern to areas like Progress
Village, Florida, where "a new gypsum stack is rising a few hundred yards from a
grade school." According to US News & World Report, there is evidence to suggest
cancer rates downwind of the stacks may be elevated:
"Some epidemiological studies suggest that lung cancer rates among nonsmoking
men in the phosphate region are up to twice as high as the state average. Acute
leukemia rates among adults are also double the average. An industry -sponsored
study of male phosphate workers, however, found lung cancer rates no higher
than the state average. There is no proof that mine wastes cause cancer, but the
evidence is worrisome."
10. Will radioactive gypsum be added to roads?
Rail cars carrying sulfur to process phosphate rock, with giant gypsum stack
looming in background.
With the growing realization that gypsum stacks represent a serious environmental threat
to Central Florida, both now and for generations to come, the phosphate industry has
been looking into ways of reducing the size of the stacks (and the size of their liability.)
In an interesting parallel to fluoride, the phosphate industry is looking to turn its
gypsum waste into a marketable product: as a potential cover for landfills, as a
soil conditioner, and as a base material for roads.
According to Robert Vanderslice, head of Phosphate Management for Florida's
Department of Environmental Protection, the gypsum is a "good material to
replace lime rock in roads. Lime rock will run out at some time, and we're still
building a lot of roads. Building roads with phosphogypsum would consume quite
a bit of gypsum."
In 1995, a "Phosphogypsum Fact -Finding Forum" organized by the Florida Institute
of Phosphate Research, presented a "message aimed straight at Washington:
Relax the rules on using gypsum and the mountains will gradually disappear."
As of yet, however, the EPA does not appear willing to relax its rules and lift its
ban on commercial uses of gypsum. According to the Tampa Tribune, "EPA's limit
for use is 10 picocuries of radium per gram, well below the levels usually found in
the mounds."
A recent statement from the EPA reads:
"Only two uses (for the gypsum) are permitted: limited agricultural use and
research. Other uses may be proposed, but otherwise the phosphogypsum must
be returned to mines or stored in stacks."
11. Commercial Uranium Production
While the presence of uranium decay -products makes gypsum a tough sell for the
phosphate industry, the uranium has, at various times, presented the industry
with a business opportunity of its own.
One of the lesser -known -facts about the phosphate industry is that its processing
facilities have produced and sold sizeable quantities of uranium.
In 1997, just two phosphate plants in Louisiana produced 950,000 pounds of
commercial uranium, which amounted to roughly 16% of the domestically
produced uranium in the US.
In 1998, the same two plants produced another 950,000 pounds, but due to
declining market prices for uranium, both plants have since ceased production.
If market prices improve, however, 4 US phosphate plants (2 in Louisiana & 2 in
Florida) would have the capacity to produce a combined 2.75 million pounds of
uranium per year, according to the Department of Energy (DOE). The DOE has
termed these 4 facilities "Nonconventional Uranium Plants."
12. Cold War Secrets & Worker Health
The Department of Energy has not always been so open about the uranium -
making potential of the phosphate industry. During the Cold War, its predecessor
institution, the Atomic Energy Commission (AEC), kept this fact closely under
wraps - even to the workers who were, unknowingly, handling large quantities of
the radioactive material.
In Joliet, Illinois, it has only recently come to light that the local phosphate plant
had secretly produced some 2 million pounds of uranium for the US government
in the years 1952 to 1962. According to local newspaper reports, the cancer rates
of people who worked at the plant, especially "Building 55" where the uranium
was processed, are unusually high.
"We used to kind of joke that if you worked for Blockson, you got cancer," quipped
Vince Driscoll, the son of a cancer -stricken worker.
Today, with the Cold War over, it is becoming clear that workers in the phosphate
industry need special protection. According to a report from the European
Commission:
"Processing and waste handling in the phosphate industry is associated with
radiatiah levels of concern for workers and the public. The level of protection for
these groups should be more similar to the level of protection that is state of the
art in other industries, particularly the nuclear industry."
13. Wastewater Issues
While the radioactivity of the gypsum stacks has probably been the key health concern
of the EPA, it is not the only one.
Resting atop the phosphate industryes gypsum piles are highly -acidic wastewater
ponds, littered with toxic contaminants, including fluoride, arsenic, cadmium,
chromium, lead, mercury, and the various decay -products of uranium. This
combination of acidity and toxins makes for a poisonous, high -volume, cocktail,
which, when leaked into the environment, wreaks havoc to waterways and fish
populations. As noted by the St. Petersburg Times, "Spills from these stacks have
periodically poisoned the Tampa Bay environs. "
One spill, in 1997, from a now -defunct gypsum stack in Florida, "killed more
than a million fish."
"Strike the Alafia River off your list of fishing spots," wrote one journalist after the
spill. "It's gone, dead as a sewer pipe, killed by the carelessness of yet another
phosphate company."
Today, the same gypsum stack which caused this particular spill, -is considered by
Florida's Department of Environmental Protection to be "the most serious
pollution threat in the state." That's because tropical rains over the past couple of
years have brought the wastewater to the edge of the stack's walls.
As noted by the Tampa Tribune, "The gypsum mound is near capacity, and a wet
spring or a tropical storm could cause a catastrophic spill."
To prevent such a spill, which was all but inevitable, the EPA recently agreed to let
Florida pursue "Option Z": To load 500-600 million gallons of the wastewater onto
barges and dump it directly into the Gulf of Mexico.
The dumping of the wastewater into the Gulf represents the latest in a series of
high -profile embarrasments for Florida's phosphate industry; one of the most
dramatic of which happened on June 15, 1994.
On that day, a massive, 15-story sinkhole appeared in the middlL. of an 80 million
ton gypsum stack. The hole was so big that, according to US News & World
Report, it
"could be as big as 2 million cubic feet, enough to swallow 400 railroad boxcars.
Local wags call it Disney World's newest attraction — 'Journey to the Center of the
Earth."'
But, as US News noted,
"there's nothing amusing about it. The cave-in dumped 4 million to 6 million cubic
feet of toxic and radioactive gypsum and waste water into the Floridan aquifer,
which provides 90 percent of the state's drinking water."
And so it goes. As summarized by the Tampa Tribune:
"It's not like you can padlock the doors and walk away. The complexities of
keeping a phosphate processing plant operating are becoming clear to
government regulators now overseeing two of them. Ponds full of 1.5 billion
gallons of acid and three mountains of radioactive waste mean you just can't shut
off the machinery and turn out the lights. The state could be stuck with the plants
for years. And taxpayers would be stuck with the tab."

Prevents aluminum
Even more frightening is what one world-renowned scientist discov-
absorption
ered: Fluoride can accumulate in the brain. With every drink of water,
the fluoride levels in the brain increase — and so
does the danger to you.
The Truth About Studying Fluoride
Dr. Phyllis Mullenix, a leading neurotoxicologist,
developed a sophisticated method to study behav-
ioral patterns using a computer. She would photo-
graph interactions of test rats given fluoride and
feed the results into a computer program.
Much to her surprise, she discovered that the flu-
oride was causing significant behavioral problems,
not only when rats were exposed in the mother's
womb, but also soon after birth and even as adults.
Upon examining seven areas of the animals' brains
she found that the longer an animal drank fluoridat-
ed water, the higher the brain level of fluoride. She
also found that a high accumulation of toxins over
time reaches levels that always cause brain injury.
Critics charged Dr. Mullenix with using doses of
fluoride much higher than people are commonly
exposed to. But researchers should know that rats
have difficulty absorbing fluoride. In comparing
rats to people, the only thing that should be looked
at is the blood level; the amount of fluoride in the
blood determines the amount of fluoride reaching
the brain.
The blood levels in Dr. Mullenix's rats equaled
that seen in humans exposed to fluoride levels
approved by the Environmental Protection Agency
(EPA) as safe. Approved levels of fluoride in drink-
ing water are up to 4 parts per million, or 4 ppm.
After presenting her findings to the EPA and
National Institute of Dental Health, Dr. Mullenix
faced great opposition from colleagues. Fellow sci-
entists who once clamored to use her computer-
ized system now eschewed any communication
with her.
Her very expensive computerized behavioral
anaylsis equipment was destroyed by a contrived
"accident". In addition, all of her lab animals were
killed and their bodies incinerated.
More Studies Confirm Brain Damage
The number of studies showing significant dam-
age to various parts of the brain continues to grow,
most of the studies coming from Mexico, China,
Japan, Spain, Italy, Ireland, Sweden, Canada and
England. Very few studies come from labs in the
United States, but those that do find fluoride to be
very toxic to the brain.
Entities such as National Institutes of Health and
National Institute of Dental Health are to blame for
fewer U.S. studies as they refuse to fund fluoride
safety research.
What we do know is that in China, children who
drink fluoridated water have lower IQs than those
who don't. Many villages and cities in China have
natural fluoride levels that are high, and Chinese
scientists have found a drop of 10 points in IQ in
fluoridated cities.
But some challengers say these scientists didn't
account for possible lead exposure, so tests were
redone. The Chinese scientists made careful meas-
urements of all factors including lead and fluoride.
The end result? They found the same lowering of
IQ caused by fluoride in the drinking water.
Mexican studies fared no better. An article in the
journal Epidemiology showed that children drinking
water with EPA -approved fluoride levels had prob-
lems with reading and writing.
Again, care was taken to control for factors that
might adversely affect the results. In fact, urine flu-
oride levels were measured to prove that the greater
the fluoride exposure the worse the tests results.
Note that most cities set fluoride levels in drinking
water well below EPA -approved levels.
The Alzheimer's Connection
What is the connection between Alzheimer's dis-
ease and fluoride? Studies show plenty. While
drinking fluoridated water is not the cause of
Alzheimer's, there is a link.
One study found that fluoride in the drinking
water of rats caused significant reduction of a brain
receptor critical for learning and memory, which
are the same receptors reduced very early in
Alzheimer's disease.
Scientists including Dr. Phyllis Mullenix and Dr.
Albert Burgstahler, an organic chemist and editor of
Fluoride, indicated to me yet another study showing
that fluoride added to water in the presence of even
small amounts of aluminum caused severe destruc-
tion of brain cells in the part of the brain control-
ling learning and memory, the hippocampus.
Clearly, these studies demonstrate that fluoride
could cause an early onset of the disease and make
it progress more rapidly. In fact, when combined
with other toxins we all are exposed to, it can make
matters worse.
Alzheimer's patients also have dramatic increases
in gut absorption of aluminum, as do children with
Down syndrome. In one study, fluoride increased
by seven times absorption of aluminum from the
gut and significantly increased the entry of alu-
minum into the brain.
The Toxic Effect
of Fluoride and Aluminum
All of us bre exposed to numerous sources of alu-
minum — in foods, canned drinks, aluminum cans
and cookware, deodorants, vaccinations, medica-
tions and pesticides. And, as we all may know,
there is further compelling evidence that aluminum
plays a major role in Alzheimer's disease and possi-
bly Parkinson's and Lou Gehrig's diseases.
The combination of fluoride and aluminum is so
toxic that even in conceptrations half those added to
drinking water will cause severe destruction of criti-
cal brain cells. You will have a hard time thinking,
remembering and performing normal brain func-
tions with this toxic duo.
The same can be true for your children.
Combining aluminum and fluoride may very well
increase the risk of ADD, ADHD, dyslexia and
other developmental brain disorders of children,
especially when combined with other toxins from
the environment. These studies are compelling
and frightening.
The Pineal Gland:
Another Area of Concern
A recent study by Dr. Jennifer Luke at the
School of Biological Sciences at the University of
Surry in England found that fluoride accumulates
in the pineal gland in the brain. Of the pineal
glands she obtained from six elderly people dying
of unrelated causes, she found fluoride levels
2,500% higher than other areas of the brain. The
fluoride was accumulating in enormous amounts
in the calcium deposits normally found in the
pineal of older people.
So, why is this important? The pineal gland is the
source of the very important hormone melatonin,
the same hormone sold in health food stores to aid
in sleep. Melatonin regulates the onset of puberty
in boys and girls, it regulates the onset of sleep and
it protects the brain against damage by free radicals
and what is known as lipid peroxidation, the main
destructive reactions seen in all degenerative brain
diseases.
In fact, individuals with Alzheimer's disease com-
monly have lower melatonin levels than do individ-
uals of similar age.
But it is the latest findings that are so startling:
+ Young girls who live in cities with fluoride in
the water have been known to begin menstruating
five months sooner than their counterparts in non -
fluoridated towns.
+ Newborns with the lowest melatonin levels
had the most problems with behavioral develop-
ment.
+ Brain protection in adults is being altered.
Fluoride and
Baby's Brain Development
Since baby animals exposed to fluoride develop
high levels of free radicals in their brains, it makes
one wonder what happens to human babies.
Unfortunately, it is the same damage.
Researchers examined the brains of aborted
babies five to eight months into a pregnancy who
were from areas having naturally high fluoride lev-
els in the drinking water.
What researchers found was alarming: The brain
cells of the babies were grossly abnormal and nerve
fibers were not even compatible with typical human
nerve fibers. The brain cells in the babies were
grossly abnormal and the nerve fibers were mis-
placed and swollen. These brains were miswired.
Keep in mind the fluoride levels in the drinking
water were within the "safety guidelines" estab-
lished by the EPA. No other causes for this damage
were found.
Individuals who counter these results say there
was up to 4.5 ppm of fluoride in the water, and
guidelines call for only 1 ppm. I object to their fin-
ger -pointing and say it doesn't take a brain surgeon
to see that this does not leave much of a margin of
safety, especially when the EPA usually uses a 100-
times margin of safety for such toxins.
And we have seen that fluoride accumulates in
the brain, reaching levels equal to these studies. Yet
most important is the fact that even their estimates
found that the average person is taking in 3 ppm
per day through foods, drinks and pesticide expo-
sure. More accurate estimates found an average
daily consumption of fluoride of 4 to 8 ppm.
Here's a great example of how fluoride can sneak
up on you. In the South, most people drink iced tea
with their meals. All teas contain very high levels of
fluoride as well as aluminum. Because the summers
are so hot, a large number of people are drinking
large volumes of this fluoride -laden tea.
Many foods and drinks also are high in fluoride,
such as de -boned meats, gelatin and American
wines, especially California wines.
Pesticides, too, are a problem, because they con-
tain cryolite, a compound containing aluminum and
fluoride in high concentrations. Interestingly, work-
ers in cryolite industrial plants have been found to
have a high incidence of thinking disorders as well
as genetic damage.
Fluoride and Cancer
In 1975, Dr. Dean Burk, the former chief chemist
of the National Cancer Institute, and Dr. John
Yiamouyiannis conducted a study comparing can-
cer death rates in the 10 largest fluoridated cities
matched with the 10 largest non -fluoridated cities.
These cities were matched for equal cancer death
rates before the fluoridation experiment was begun.
They found that once cities began including fluo-
ride in their drinking water, cancer death rates
began to climb. After 13 to 17 years of fluoridation
of their drinking water, these cities experienced a 10
percent increase in cancer death rates compared
with the non -fluoridated cities.
The incidence of cancer would be even higher
than the cancer death rates, since many people
with cancer will not die of the disease during the
years studied.
The Centers for Disease Control and Prevention
(CDC) repeated the study using a larger number of
cities and found similar results. Interestingly, both
scientists proved their case ih court against repre-
sentatives from the National Cancer Institute.
Several other doctors found even more frighten-
ing associations between fluoridation of drinking
water and cancer incidences. Dr. Donald Austin of
the California Tumor Registry discovered the can-
cer death rates in California were 40 percent high-
er in fluoridated communities and Dr. Victor
Ceilioni showed the cancer death rates in
Canadian cities were 15 percent to 25 percent
higher in fluoridated Canadian rites compared
with non -fluoridated cities.
Although a heavy proponent of fluoridation, the
U.S. Public Health Service discovered similar results
as Drs. Austin and Ceilioni after following up its ini-
tial fluoridation program.
In the first of the fluoridated cities in the U.S. —
Grand Rapids, Michigan - the Public Health Service
found a 22 percent increase in cancer death rates
compared with the non -fluoridated control city of
Muskegon, Michigan.
We can now show a strong connection between
fluoridated drinking water and cancer death rates.
And the evidence gets even stronger. As a result of
these studies and the fact that the U.S. Public
Health Service could not defend fluoride safety,
Congress ordered a study of the problem to be con-
ducted by the Battelle Memorial Institute in
Columbus, Ohio.
The Battelle Institute announced its findings and
released proof of the connection between fluoride
and cancer of the mouth in February of 1989.
The study showed:
+ At 45 ppm, there was a 12 percent increased
incidence of oral cancers, such as cancers of the
tongue and gums. Subsequent studies did indeed
show that the incidence of oral cancers in fluoridat-
ed vs non -fluoridated cities was 33 percent to 50
percent greater.
+ Toothpaste can contain between 1,000 and
1,500 ppm fluoride.
+ Fluoride gels used in dental offices contain up
to 15,000 ppm.
+ New fluoride varnishes release a high concen-
tration of fluoride continuously in the mouth.
Fluoride, Bone Cancer and Young Men
The bones accumulate more fluoride than any
other tissue with the exception of the pineal gland.
The Battelle study found that the longer one lives in
a fluoridated community, the higher one's bone flu-
oride levels are.
In fact, animals exposed to 45 ppm of fluoridated
drinking water
showed an increase in a rare form of
bone cancer called osteosarcoma -- in human stud-
ies the fluoride concentrations in bones found lev-
els greater than 2,000 ppm.
Osteosarcoma is a tumor most commonly seen in
young men in their late teens and twenties. If the
Battelle study was accurate, one would expect to see
a rise in osteosarcoma in young men in fluoridated
communities.
All one has to do is look to the reports by the
National Cancer Institute and a 1992 study by the
New Jersey Department of Health that show heavy
increases, some as high as 50 percent, of the occur-
rence in osteosarcoma in young men. A New Jersey
study found a 3 to 7X higher incidence of this can-
cer in young men in fluoridated communities vs.
non -fluoridated.
Even more shocking is the fact that the Proctor &
Gamble Company's own scientists found a link
between fluoride ingestion and bone cancer risk
before they began adding fluoride to Crest tooth-
paste. This information was not released voluntarily
but required a Freedom of Information lawsuit to
pry it loose.
Another P&G study shows that scientists also
found genetic damage to cells exposed to just 1 ppm
of fluoride, the same dose added to drinking water.
This relation to genetic damage has been confirmed
by several independent researchers.
Other types of cancers associated with fluoride
exposure include:
+ Industrial exposure to airborne fluoride shows
a 35 percent increase in lung cancer.
+ There is also a 129 percent higher incidence in
laryngeal cancer.
+ Significant data show an 84 percent increase in
bladder cancer.
In fact, in the Battelle study fluoride caused a
rare liver tumor that can be produced in experimen-
tal animals by only one other toxin — uranium.
Does Fluoride Cause Crippling?
Skeletal fluorosis is a rarely used term in the
United States but often discussed in medical jour-
nals overseas. Not that it doesn't occur in the U.S.,
it's just shrouded in secrecy. Few American doc-
tors have even the slightest understanding of the
condition.
As you have learned, the bones accumulate fluo-
ride in very high concentrations and continue to do
so the longer you drink fluoridated water. Dr. Hardy
Limeback, a professor of dentistry at the University
of Toronto who also conducted studies on fluoride
levels in the bones of people living in fluoridated
communities versus non -fluoridated communities,
found that the former had fluoride bone levels two
times higher than the latter.
In 1993 the National Academy of Sciences admit-
ted that when bone fluoride levels reached 7,500 to
8,000 ppm, stage 2 and 3 skeletal fluorosis was like-
ly to occur.
So, what is skeletal fluorosis? When fluoride accu-
mulates in bones it stimulates the bone -generating
cells, known as osteoblasts, to over -produce bone
calcium in what are commonly known as bony
overgrowths or bone spurs. These can appear over
the joints, within ligaments and especially within
the spinal bones. With extensive overgrowth (stage
2 and 3) a person becomes crippled.
Of particular concern is the bone overgrowth on
the spinal bones, because they can compress spinal
nerves and even the spinal cord. We call this condi-
tion spinal stenosis.
Spinal stenosis is a very common disease that can
affect the young as well as the elderly. It is much
more common after age 50. I have operated on hun-
dreds of people with this condition. Compression of
the spinal cord in the neck can result in quadriple-
gia -- permanent paralysis from the neck down.
I have examined the spines of people from India
with this condition proven to be caused by fluoride
excess in the drinking water, and it is exactly the
same as we are seeing in this country. Incredibly,
no one has conducted studies in this country
measuring fluoride bone levels in this crippling
condition. It is not even mentioned in our medical
textbooks.
Bone Fractures and Fluoride
One of the worst things that can happen to an
elderly person is to fracture a hip. With mortality
rates of up to 50 percent of those who do fracture
their hips, many who survive never walk again.
Any type of bone fracture is very painful and unfor-
tunately quite common among the elderly.
When fluoride is present in the bones it is shown
to weaken the cortical bone, that part that gives the
bone strength - bad news for fracture sufferers. One
study among Utah's Mormon community found that
fluoridation of the drinking water increased the
incidence of hip fractures by 27 percent in women
and 41 percent in men.
Fluoride and the Thyroid
In the past, medical doctors used fluoride tablets
to reduce the activity of overactive thyroid glands
(hyperthyroidism). Subsequent studies have found
that fluoride also suppresses the activity of the nor-
mal thyroid as well, inducing a condition called
hypothyroidism or goiter.
A study done in China found that thyroid
enlargement was almost 10 times greater in areas
with high fluoride levels in the drinking water.
Since the thyroid accumulates more fluoride than
any other gland, studies were done and confirmed
on animals that fluoride in drinking water inhibits
the thyroid gland. It gets worse when iodine levels
are very low or very high.
Pregnant women with low thyroid function are at
a greater risk for their babies having severe mental
retardation, thereby impacting the fetuses' brain
development, according to an article published last
year in The Journal of Clinical Investigation.
The article indicates that d child's mental devel-
opment was directly related to the mother's thyroid
function during the 12th week of pregnancy. With
fluoride's ability to suppress thyroid function, even
mild depression of the thyroid can cause a signifi-
cant increase in the incidence of mental retardation
in children in fluoridated communities. This may
explain the finding of significant increases in Down
syndrome in fluoridated communities.
Fluoride, Male Infertility
and Impotence
Reduced sperm counts and infertility in men who
work in cryolite (50% fluoride) and aluminum facto-
ries have been reported. Supporting evidence shows
that fluoride added to the drinking water of experi-
mental animals causes significant reductions in
sperm counts, lower testosterone levels and a dra-
matic increase in abnormal, mutated sperm. This
has been shown in many animal species as well as
in humans.
Male fertility has been hampered by free -radical
generation in the areas of the testes that produces
sperm. This could explain not only infertility in
many men living in fluoridated areas but also
genetic defects in their offspring should they be
able to conceive, especially those with higher
intakes of fluoride.
What About the Teeth?
Let us not lose sight of the reason for fluoridating
drinking water in the first place: preventing cavi-
ties. After all, didn't the American Dental
Association promote the idea that fluoridating
drinking water could reduce cavities by as much as
50 percent? In fact, subsequent examination of
these studies found no reduction in cavities.
One dentist commissioned by the U.S. Public
Health Service found that pebple in high -fluoride
areas had fewer cavities but they also suffered from
a condition called dental fluorosis, which leaves the
teeth brown and mottled.
Recent studies have shown an incidence of dental
fluorosis from 30 percent to 60 percent in fluoridat-
ed communities. With so many generations having
been exposed to high fluoride levels over a lifetime,
the problem can only get worse.
In essence, does fluoridation of drinking water
prevent cavities? The largest study ever done in this
country, involving 39,000 schoolchildren, found no
overall reduction in cavitles in communities with
fluoride in their water.
Additionally, the largest worldwide study shows
that children who live in areas with no fluoride in
the water had lower cavity rates.
In fact, cavity rates dramatically fell even before
fluoride was added to toothpaste. It is also impor-
tant to note that virtually all European countries
have banned water fluoriidation. The most heavily
fluoridated country by government policy in the
world is the United States.
Another study, by Dartmouth University, shows
that children living in fluoridated communities

have blood lead levels twice that of non -fluoridated
communities. That could mean more incidences of
poor learning ability, increased violence, higher sui-
cide rates and greater drug use among children.
What Products Should You Avoid?
Simply put, stop using fluoride in its many forms.
This includes avoiding:
+ Teas high in fluoride
+ Fluoridated water
+ Toothpaste with flouride
+ Vaccinations, since they contain fluoride and
aluminum
+ Pesticides or herbicides near or in your home
+ Medications containing fluoride
Also, do not use lemon in your tea, since it will
increase aluminum absorption enormously.
Do not cook in aluminum or Teflon -coated cook-
ware, and avoid using Teflon products. 00-

1 Renton measures fluoride levels dally in the distribution system. Beginning in April 2016, Renton lowered the fluoride level to 0.7 ppm, which is the new
level recommended by the Washington State Department of Health. Renton citizens voted to add fluoride to the drinking water in 1985.
2. The EPA recommends 20 ppm as a level of concern for people on a sodium -restricted diet. Renton adds sodium hydroxide to prevent corrosion of
plumbing. Sodium hypochlorite is added to water from the Maplewood wells for disinfection and to remove naturally occurring ammonia.
3. There were 45 samples tested for I ?ad and copper. All of the samples tested had levels far below the Action Levels for both lead and copper.
4. EPA has established MRLs for UC11{t5 based on the capability of the analytical method. It is not based on a level established as 'significant' or 'harmful.'
The detection of a UCMR5 contaminant does not represent cause for concern, in and of itself. The purpose of unregulated contaminant monitoring is to
help the EPA determine their occurrence in drinking water and potential need for future regulation.
5 There were six samples tested for 29 PFAS and lithium. Only one of six samples detected PFBS at a level at or above the MRL.
