| Short Description |
A survey of chemical contaminants was conducted for ten Washington lakes as part of the Washington State Department of Ecology's 1992 Lake Water Quality Assessment Project. Whole bottom-feeding fish, predator fish muscle, and bottom sediments from Potholes Reservoir, Long Lake (Spokane River), Roses Lake, Lake Sammamish, and Ward Lake were analyzed for a variety of organic compounds and metals. Duck, Spanaway, Ohop, Ketchum, and Silver Lakes were sampled for copper in sediments. (Also see abstract below) | |||

| Abstract | Long Description |
A survey of chemical contaminants was conducted for ten Washington lakes as part of the Washington State Department of Ecology's 1992 Lake Water Quality Assessment Project. Whole bottom-feeding fish, predator fish muscle, and bottom sediments from Potholes Reservoir, Long Lake (Spokane River), Roses Lake, Lake Sammamish, and Ward Lake were analyzed for a variety of organic compounds and metals. Duck, Spanaway, Ohop, Ketchum, and Silver Lakes were sampled for copper in sediments. The objectives of the survey were to assess the occurrence of potentially toxic chemicals in lake sediments and fish and evaluate the significance of the findings. Concentrations of chemicals in fish were compared to results of national and statewide surveys, and criteria for protection of human health. Chemical concentrations in sediments were compared to freshwater sediments in Washington and guidelines established for the management of contaminated sediments. |
