This week, the Massachusetts Department of Environmental Protection (MassDEP) filed two rules related to PFAS: a final soil and groundwater cleanup rule and a draft drinking water rule. The first rule requires that parties responsible for contamination clean up groundwater that could be used as drinking water, meeting a limit standard of 20 parts per trillion (ppt) for the sum of six PFAS compounds. It also establishes a cleanup standard for specific PFAS limits in soil. The second rule would establish a Maximum Contaminant Level of 20 ppt for the sum of six PFAS compounds in drinking water.
MassDEP will host five public hearings on the draft drinking water standards and will accept comments through February 28. For more info on PFAS in Massachusetts, see here.
