| Description | This report presents results of a multi-year study to characterize pesticide concentrations in salmon-bearing surface waters. Monitoring occurred in five basins: one urban basin (Thornton Creek in the Cedar-Sammamish) and four agricultural basins (lower Skagit-Samish, lower Yakima, Wenatchee, and Entiat). During 2006-2008, 71 pesticides were detected. Seven of these failed to meet an assessment criterion: permethrin; chlorpyrifos; diazinon; azinphos-methyl; malathion; endosulfan; and total DDT. Pesticide concentrations found likely do not directly affect salmonids, but at some sites may affect aquatic invertebrate populations. During 2010, an anomaly in the 2006-2009 analytical method for carbamates was found. This anomaly caused the false positive identification of the degradate compounds 1-naphthol, aldicarb sulfone, and aldicarb sulfoxide. The corrected report and appendices were posted on October 22, 2010. |
