Proceedings of the Agricultural Impacts on Ground Water: A Conference

This paper describes the preliminary results of a study conducted by the
California Department of Food and Agriculture which compares the soil distribution
of herbicides in two ground water basins in the state. In a previous
study, residues of several agricultural chemicals were detected in
numerous wells in two inland ground water basins, while only one contaminated
well was found in two coastal basins. The present study was designed to
provide further information on the effects of cultural practices, climatic
conditions, and soil and geologic factors in each basin on pesticide mobility.
