Although groundwater is a safe, reliable source of drinking water for millions of people nationwide, high concentrations of some chemical constituents can pose potential human-health concerns. Some of these contaminants come from the rocks and sediments of the aquifers themselves, and others are chemicals that we use in agriculture, industry, and day-to-day life."

The results for the Nation are summarized in a single circular. Samples were collected from 6,600 public-supply, domestic (private), and monitoring wells, and analyzed for a wide range of contaminants and constituents, including pesticides, nutrients, and radionuclides. Explanations of the findings presented in these circulars improve our understanding of the natural and human factors that affect the occurrence of contaminants in the Nation\u2019s groundwater."

Contaminants in groundwater can also affect the health of our streams and valuable coastal waters. By knowing where contaminants occur in groundwater, what factors control contaminant concentrations, and what kinds of changes in groundwater quality might be expected in the future, we can ensure the availability and quality of this vital natural resource in the future."
