Description The Departments of Ecology and Agriculture have conducted surface water pesticide monitoring in salmon-bearing streams since 2003.

The 2007 project evaluated the adequacy of the current weekly sample regime. Pesticide detections from weekly surface water grab samples were compared to daily grab samples over 22 days. Detections from two Passive Samplers were also compared to the daily grab sample results.

The study site was Marion Drain, a 19-mile agricultural drain that discharges into the Yakima River. Marion Drain is used by salmonids including: Chinook, Coho, and endangered Steelhead.

The Department of Ecology used this poster at the Sixth National Monitoring Conference in Atlantic City, NJ, during May 2008. See link to the technical study below.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
