| Short Description |
A reconnaissance survey was conducted to refine methods and identify sampling sites for the surface water portion of the Washington State Pesticide Monitoring Program. Water samples were collected from 11 freshwater sites representing urban, forest practices, and agricultural pesticide use. Samples were analyzed for 162 pesticides and breakdown products; including organochlorines, organophosphates, nitrogenous pesticides, pyrethroids, chlorinated herbicides, carbamates, volatile pesticides, urea pesticides, glyphosate, and diquat and paraquat.

| Abstract | Long Description |
A reconnaissance survey was conducted to refine methods and identify sampling sites for the surface water portion of the Washington State Pesticide Monitoring Program. Water samples were collected from 11 freshwater sites representing urban, forest practices, and agricultural pesticide use. Samples were analyzed for 162 pesticides and breakdown products; including organochlorines, organophosphates, nitrogenous pesticides, pyrethroids, chlorinated herbicides, carbamates, volatile pesticides, urea pesticides, glyphosate, and diquat and paraquat. Twenty-three target pesticides and nine non-target compounds were detected at ten of the eleven sites. Carbamates, volatile pesticides, urea pesticides, and diquat and paraquat were not detected in any of the samples. Results are compared to available water quality criteria and historical data. Findings from this survey will be used to design the final monitoring plan for pesticides in state surface waters. |
