Description |
In 2003, the Washington State Toxics Monitoring Program analyzed 25 composite samples of edible fish tissue from ten sites. Contaminants found were mercury, PCBs, dioxins/furans, flame retardants, and over a dozen chlorinated pesticides.
Fish tissue samples exceeded water quality standards at eight sites: Banks Lake, Sprague Lake, Scooteney Reservoir, Silver Lake, Lake Washington, Lacamas Lake, Roses Lake, and the Spokane River. Few contaminants were detected in samples from Curlew Lake and Twin Lakes.
Water samples from ten other sites were analyzed for 115 chlorinated, organophosphorous, and nitrogen pesticides. Only six pesticides were detected at low levels and low frequencies. |
