Sample Location Approximate Flow Turbidity NTU/Transparency pH Compliance
SE of site: 111th Ave
swale outfall
10 6.5 yes
ADDITIONAL COMMENTS:
No sediment was observed leaving the site. AESI took a water sample from the swale SE of the site. The turbidity and pH
of the sample were 10 NTU and 6.5, this is in compliance with the SWPP. While onsite, AESI observed some silt fencing
knocked down. AESI notified the client and recommended repairing the silt fencing around the perimeter of the site and
adding additional silt socks in the catch basins off of 111th Ave. AESI also observed several slightly turbid puddles onsite.
AESI talked to the contractor about the potential of a temporary sediment pond to impound onsite water. The
contractor notified AESI that they will be sweeping the street later in the day.
