The Massachusetts Department of Environmental Protection (MassDEP) proposes to revise its regulations at 310 CMR 42.00 for the Certification and Operation of Environmental Analysis Laboratories to add a new certification category for Per- and Polyfluoroalkyl substances (PFAS). Changes to 310 CMR 22.00, the Drinking Water regulations, are also proposed which will add references to the appropriate laboratory methods to be followed by certified laboratories. MassDEP is separately proposing revisions to the Timely Action and Fee regulations at 310 CMR 4.00 to create a permit fee category for PFAS laboratory certification.
