Massachusetts Proposes New PFAS Regulations as States Tackle Contamination
As in previous postings, we discuss recent state regulatory initiatives aimed at addressing groundwater and drinking water contamination by per- and polyfluoroalkyl substances ("PFAS"). PFAS are a group of synthetic chemicals that have been used widely in consumer and industrial products since the 1940s. Major applications have included coatings for paper and cardboard packaging products, carpets, textiles with water and oil repellency, non-stick surfaces, and firefighting foams. Due to their chemical structure, PFAS stay in the environment for a long time and do not degrade easily. PFAS have been detected in air, surface water, groundwater, drinking water, and soil. They even have been found in grocery store items, such as meat, fish, dairy, and prepared chocolate-cake. The widespread use and persistence of PFAS in the environment, together with growing evidence that low-level exposure may lead to adverse health effects, has increased concerns about safe levels of human exposure to PFAS. In response, many more state and, to a lesser extent, federal initiatives have been undertaken to regulate PFAS. As discussed below, recently the Massachusetts Department of Environmental Protection (the "MassDEP") has proposed to regulate PFAS within the framework of the Commonwealth’s Massachusetts Contingency Plan.
