Pollution of ground water by agricultural chemicals and nitrate is one of the major problems facing agriculture in the 1980s. Before this problem is resolved additional research is needed in the following areas: 1) identification of areas within each state where ground water contamination is most likely to occur; 2) data to establish levels of pesticides in ground water that present health risks; 3) the fate and transport of pesticides in soil and underlying strata; 4) improved nitrogen use efficiency of agronomic and horticultural crops and improved management of nitrogen fertilizers; and 5) cropping and management systems that reduce or eliminate the need for problem pesticides. Improved research information in these areas should assist society in resolving current problems of ground water contamination.
