Private Wells


As a private well owner, you are responsible for the quality of your own drinking water. It is important to test your well regularly to make sure the water is free of contaminants and safe to drink.  Well water is required to meet standards set by the Concord Board of Health “Minimum Sanitation Standards for Private and Semi-Public Water Supplies”.   These standards are based on the U.S. Environmental Protection Agency (EPA) and Commonwealth of Massachusetts guidelines for private drinking water wells.

Routine maintenance and inspection of water wells can help protect water quality, ensure your well is operating properly, prolong the useful life of the well system, and protect your investment. Greatest of all these is the protection of your health, as water quality issues can have adverse health impacts without any detectable indicators.

Please see the Concord Health Division publication Protect Your Family’s Health: A Guide to Water Quality Testing for Private Wells  for helpful information you should know about your private well.
