Pesticides are chemicals used to kill or control pests. They are commonly used in agriculture, forestry, along roads and railroads, on park and golf courses, on lawns and gardens, in homes and other buildings, and on pets. For this study, we tested drinking water samples for 82 different pesticides and pesticide-related chemicals.
- Learn about pesticides in drinking water
- Learn how pesticides get into groundwater
- See Pesticides Publications and Resources for more resources, including how to report pesticide complaints, how pesticides are regulated, and links to agencies overseeing pesticide use
