| Short Description |
Fourteen wells near Woodland, Washington, were sampled during May and June 1993 for 124 pesticides and nitrate+nitrite as nitrogen. Field measurements of water temperature, pH, and specific conductance were also made. Seven pesticides were detected in the initial samples; atrazine, simazine, diuron, bromacil, tebuthiuron, pentachlorophenol, and 1,2 dichloropropane. One or more of these chemicals were detected in nine wells, however, concentrations were below health related levels set by the EPA. A second sample from the nine wells confirmed the presence of these pesticides. In one well, the nitrate+nitrite as N concentration exceeded the 10 mg/L standard for public drinking water. | |
