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.
UPDATE: Regional Water Quality Sample Results (Nov 2019)
The Massachusetts Department of Environmental Protection issued a Notice of Responsibility to the Department of Fire Services (DFS) on October 24th, 2019 citing levels of per- and polyfluorinated alkyl substances (PFAS) detected in water in White Pond and the DFS grounds.
PFAS is a common chemical, and specifically found in fire suppression materials, namely AFFF foam. DFS no longer uses materials containing PFAS in their fire training.
DFS hired GZA as a Licensed Site Professional (LSP) to investigate the origins of the contamination, the scope of the contamination, and the possible migration of the contamination.
White Pond is not a current water source for the Town of Maynard, however the Town does retain rights to utilize this source.
