Description This report presents 2010 pesticide results for two urban basins (Thornton Creek in the Cedar-Sammamish basin and Longfellow Creek in the Green-Duwamish basin) and four agricultural basins (lower Skagit-Samish, lower Yakima, Wenatchee, and Entiat).

Changes during 2010 include purchase of a new laboratory instrument that allowed for better sensitivity and has significantly reduced identification uncertainty, thus decreasing the potential for false positive and negatives.

During 2010 very few pesticide detections were above (did not meet) water quality criteria or standards. An intensive triennial review of pesticide results will be conducted after the 2011 monitoring season.
