Investigations

Agricultural Chemicals in the Upper Midwest

The occurrence, transport, and fate of agricultural chemicals is being studied in a 12-State area in the upper Midwest. Scientists are identifying factors that affect dispersal of these chemicals in surface and ground waters from point of application and are evaluating the resulting effects in small streams and large rivers, at reservoir outfalls, in shallow ground water, and in precipitation. The goal is to provide the general scientific basis needed to develop agricultural management practices that protect the quality of the region's water resources.
