Description The report describes results of pesticide sampling in Mission Creek basin, a Wenatchee River tributary with its confluence at Cashmere. Objectives were to assess types and concentrations of pesticides in Mission Creek and its tributaries, and determine which drainages are contributing pesticides to Mission Creek. Concentrations of DDT, azinphos-methyl, and chlorpyriphos were at times above criteria to protect aquatic life from chronic exposure. In addition, DDT was above levels derived to protect human health from consumption of contaminated fish tissue. Other pesticides detected were endosulfan compounds, methoxychlor, diazinon, dimethoate, bromacil, dichlobenil, and atrazine.
