Study IDWHOB002
Study NameWenatchee River PCB Source Assessment
EIM Data Entry Review StatusReviewed
Study TypeGeneral environmental study
Study PurposePCB concentrations in fish tissue from the Wenatchee River are among the highest in Washington State. The goal of this project is to investigate potential PCB sources within the Wenatchee River Basin. Sampling will include the use of semi-permeable membrane devices, solid-phase extraction disks in continuous low-level aquatic monitoring (CLAM) devices, and sediments. Samples of the lower food web will also be collected (periphyton and macroinvertebrates) and measured for PCB concentrations.
