Drinking Water Exposure to Chemical and Pathogenic Contaminants: Pesticides

Pesticides, including those used to combat insects, bacterial/viral/fungal infestations, and weeds, are used in in large quantities in U.S. agriculture as well as at our homes. The toxicity of pesticides in drinking water and their behavior in the environment varies from compound to compound. The USEPA maintains Maxiumum Contaminant Levels for several pesticides. Although the USEPA regulates and provides guidance on the use of pesticides, the application is often directly to the environment and consequently some pesticides are transported to water resources and can become drinking water contaminants.

The U.S. Geological Survey provides environmental occurrence data and information for a wide range of pesticides (with and without MCLs). In addition, many USGS research projects investigate the fate and transport of pesticides in the environment.
