New PFAS Maximum Contaminant Level for Drinking Water in MA

As Per- and Polyfluoroalkyl substances (PFAS) continue to be a prevalent emerging contaminant in drinking water across the Northeast, the Massachusetts Department of Environmental Protection (MassDEP) is making changes to the Massachusetts Drinking Water Regulations. MassDEP recently announced a new Maximum Contaminant Level (MCL) for six PFAS. The PFAS6 MCL is now 20 parts per trillion (ppt) for the sum of PFOS, PFOA, PFHxS, PFNA, PFHpA, and PFDA.
