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 Water Quality Association maintains a database, searchable by water quality issue, that contains descriptions and suggested treatment methods for common domestic well water quality contaminants. The database is found here:
The US EPA also provides a detailed booklet, available online, that discusses common contaminants. The booklet can be found here:
