Drinking water in the well serving a private home on Chequessett Neck Road contained nearly seven times the state’s limit for PFAS when it was tested in the spring of 2022. State and local health authorities are still working to find the source of contamination. The test was part of a Massachusetts state program offered to residents of towns where at least 60 percent of the homes have private wells.
The results for Wellfleet showed the Chequessett Neck Road residential well had tested at 139 parts per trillion (ppt). Massachusetts has set a limit of 20 ppt for the sum of six PFAS in drinking water.
