The U.S. Environmental Protection Agency introduced a new drinking water standard to reduce exposure to PFAS, chemicals linked to health risks like cancer. Massachusetts is one of 11 states with existing PFAS limits, which are different from the new federal guideline. As a result, the Massachusetts Department of Environmental Protection estimated that 95 water systems across the state will need to upgrade their water system to address PFAS for the first time under the new federal rules.

Climate and Environment Correspondent Barbara Moran joins The Common with more on the new federal rule and its impact on the local water systems.
