Additional Domestic Well Information

Many agencies maintain Websites focused on domestic well water quality concerns. Additional information can be found at:

The United States Geological Survey also monitors the quality of water from Domestic Wells in the United States as part of the National Water-Quality (NAWQA) Program. The large number of contaminants assessed as part of this program, and the broad geographic coverage of the study provides a baseline for an improved understanding of groundwater quality in major aquifers in the United States.

The US EPA also provides a detailed booklet, available online, that discusses common contaminants. The booklet can be found here:
