Book excerpt: The contamination of drinking water supplies by nonpoint source (NPS) pollution continues to be an important issue in environmental and water resource management. The degradation of groundwater by NPS pollutants, particularly pesticides, has become a growing public concern mainly because of the potential of long-term health effects. According to the 1994 Special Review issued by the U.S. Environmental Protection Agency (EPA), there are concerns that residues of atrazine in drinking water may increase cancer risks to the public. Thus, there is a strong need for effective tools for evaluating the environmental processes that influence the fate and transport of pesticides in the subsurface environment and the potential health risks associated with drinking contaminated water supplies.
