Well Water Safety

Through our involvement with the New England Regional Water Quality Program, we have partnered with the Maine Center for Disease Control and the US EPA Region 1 to help homeowners who are responsible for their own drinking water supply.

In Maine, about half of our residents get their water from a private source. These homeowners are responsible for having their water tested to make sure it is safe. How often you should test depends on what you’re testing for — for example, well water should be tested for bacteria and nitrates every year, while well water should be tested for arsenic, radon, and uranium every three to five years.

For well water information, including a complete listing of what to test for, please visit’s Private Well Water Safety and Testing. To find a lab to test your drinking water, visit Maine Health and Environmental Testing Laboratory’s Order Water Testing Kits website (we do not provide this service).
