What contaminants must the well water be tested for?
That depends on where you live. All wells must be tested for the following contaminants: total coliform bacteria, iron, manganese, pH, all volatile organic compounds (VOCs) with established Maximum Contaminant Levels, nitrate, and lead. If total coliform bacteria are detected, a test must also be conducted for fecal coliform or E. coli. Private wells located in certain counties will also have to test for arsenic, mercury and 48-hour rapid gross alpha particle activity.
