Yes www.aesgeo.com TESC REPORT DATE CSWGP PROJECT NO. TESC REPORT NO. 11/15/2022 WAR307077 20130674E003 099 Sample Location Approximate Flow Turbidity NTU/Transparency pH Compliance 111th Ave Swale outfall 38 7.0 Yes ADDITIONAL COMMENTS: While onsite, AESI observed some silt fencing knocked down and sediment trackout. AESI took a water sample from the outfall swale on 111th Ave. The turbidity came back at 38 NTU and 7.0 pH. AESI notified the contractor and recommended repairing the silt fencing around the perimeter of the site, adding additional silt socks in the catch basins off of 111th Ave, sweeping the roads to clear the sediment, and adding straw over exposed soils.
