There are no state or federal regulations regarding private wells and the chemicals known as PFAS. This gap creates inequities for the 600,000 Massachusetts residents who get drinking water from private wells in mostly rural communities.
Massachusetts' limit on PFAS in drinking water is one of the strictest in the country. Removing the chemicals from drinking water can cost millions, and so far, communities have footed most of the bills. With new regulations expected this year, the costs may get much higher.
