This summer, the MA Department of Environmental Protection and the Environmental Protection Agency sampled Maynard drinking water wells to test for per – and polyfluoroalkyl substances (PFAS), a group of man-made chemicals that include PFOA, PFOS, GenX, and many other chemicals. The federal limit of these chemicals in drinking water is 70 Parts Per Trillion (PPT). The MA Department of Environmental Protection is considering decreasing the limit in Massachusetts to 20 PPT.
Results of the Maynard sampling ranged from 4.1 to 9.4 PPT, significantly below the federal limit, and the proposed state limit. Based on these results, the Town Administrator’s Office agrees with the town’s water engineering firm Stantec, that PFAS/PFOA at the current drinking water sources is not a concern at this time.
