Yes www.aesgeo.com TESC REPORT DATE CSWGP PROJECT NO. TESC REPORT NO. 1/20/2023 WAR307077 20130674E003 108 Sample Location Approximate Flow Turbidity NTU/Transparency pH Compliance 111th Ave Swale outfall 4 6.0 Yes ADDITIONAL COMMENTS: While onsite, AESI observed the silt fence to need repairs in some areas around the site. AESI recommends repairing the silt fence around the perimeter and replacing the silt socks in the catch basins on 165th St. The contractor notified AESI that utility and sewer work would be wrapping up in the coming weeks and gutters would be installed shortly after. AESI took a water sample from the 111th Ave swale outfall. The turbidity of the water came back at 4 NTU. This is in compliance with the SWPP.
