Description This is the third addendum to the QAPP:Wenatchee River PCB and DDT Source Assessment. Sampling results from the most recent study of PCB sources identified two chemically-distinct sources to the Wenatchee River, one located near the City of Cashmere and the second near the confluence of the Wenatchee River and the Columbia River. The recommendations from the 2018 study were to investigate these PCB sources in detail. This third addendum to the QAPP describes a plan to investigate the upstream source of PCBs near the City of Cashmere.
