Description The Department of Ecology conducted a study of West Medical Lake fish tissue, sediment, and effluent from the Medical Lake municipal wastewater treatment plant. Toxics analysis included polychlorinated biphenyls (PCBs), 2,3,7,8-tetrachlorodibenzodioxin (TCDD), and other chlorinated dioxins and furans.

The purpose of the study was to determine current levels of toxics and verify the 303(d) listings for the lake. The Department of Health was provided study data to evaluate if a fish consumption advisory is needed.

In fish tissue, PCBs did not meet standards but TCDD was not detected. In sediment, Freshwater Sediment Quality Guidelines were met. In effluent, PCBs were low and TCDD was generally not detected.
