| Description | This report presents results of a multi-year study to characterize pesticide concentrations in salmon-bearing surface waters. Monitoring occurred in six basins: two urban (Thornton Creek in the Cedar-Sammamish, and Longfellow Creek in the Green-Duwamish) and four agricultural (lower Skagit-Samish, lower Yakima, Wenatchee, and Entiat). During 2009-2011, 74 pesticides or pesticide related compounds were detected. Twelve of these failed to meet an assessment criterion: bifenthrin, chlorpyrifos, DDVP, diazinon, endosulfan, endosulfan sulfate, ethoprop, malathion, methiocarb, metolachlor, methomyl, and total DDT. Pesticide concentrations found likely do not directly affect salmonids but at some sites may affect aquatic invertebrate populations. Decreasing trends in pesticide concentrations were seen for 16 select pesticides, and increasing trends in concentrations were seen for 10 pesticides. |
