Are Agricultural Pesticides in Surface Waters of the Central Columbia Plateau?


Book Description

Surface-water sites representing four drainage basins with different farming practices were sampled by the U.S. Geological Survey as part of its National Water-Quality Assessment Program. Samples were taken one to five times a month from March 1993 through May 1994. Detections of pesticides usually, but not always, were related to pesticides used on crops in the drainage basins.
