| Abstract | Long Description |
Lake Chelan is listed under Section 303(d) of the federal Clean Water Act for non-attainment of EPA′s human health criteria for 4,4′-DDE (DDT metabolite), PCB-1254, and PCB-1260 (polychlorinated biphenyls) in fish tissue. Roses Lake, tributary to Lake Chelan via Stink Creek, is also listed for 4,4′-DDE in fish and was included in the present study. The 303(d) listings are based on fish tissue studies conducted by the Department of Ecology in 1992 and 1994. These legacy chemicals are not produced or used in the United States today but persist in the environment. This quality assurance project plan describes methodology to complete a Total Maximum Daily Load (TMDL) study that will be conducted to identify potential sources of the listed pollutants and determine the maximum amount these waterbodies may assimilate without violating water quality standards. The study will determine current levels of DDT, its metabolites, and PCBs in water, sediments, and fish throughout the basin. |
