from Mass Water Works Assoc: CLF files petition for MA to regulate PFAS: The Conservation Law Foundation (CLF) sent a petition to MassDEP last week asking them to establish a Treatment Technique standard for PFAS chemicals (see petition). CLF contends that “MassDEP must immediately adopt a drinking water standard that protects residents of Massachusetts from exposure to all PFAS compounds.” MWWA understands that CLF has filed similar petitions in Vermont and Connecticut. (see: Protecting New Englanders from Toxic Chemicals in Drinking Water: CLF urges states to take immediate action in the absence of federal safeguards). While the petition states the preferred approach is a treatment technique standard, CLF states that if MassDEP does not feel they can do that, they should do an MCL for the PFAS class or an MCL for each individual PFAS compound. They also urge MassDEP to immediately adopt Vermont’s health advisory of 20 ppt for the PFAS class as an MCL. See their 2018.10.28 CLF MA_PFAS_Petition
