Surface Water Monitoring Program for Pesticides in Salmonid-Bearing Streams, 2007 Data Summary. A Cooperative Study Conducted by the Washington State Departments of Ecology and Agriculture.

摘要

From February through October 2007, the Washington State Department of Ecology and the Washington State Department of Agriculture conducted pesticide sampling in the Cedar-Sammamish, Lower Skagit-Samish, Lower Yakima, Wenatchee, and Entiat watersheds. The sampling was part of the Surface Water Monitoring Program for Pesticides in Salmonid-Bearing Streams. The purpose of this data summary is to (1) provide results of the 2007 sampling program, and (2) propose changes for the 2008 program. For the 2007 results, the report summarizes water quality results and discusses quality of the data. Year 2007 is the first in a three-year study cycle to investigate pesticides in the Wenatchee and Entiat watersheds, the second in a three-year cycle in the Skagit-Samish watershed, and the fifth in a six-year cycle in the Cedar-Sammamish and Lower Yakima watersheds.
