Requires DEP to study feasibility of using alternative water supply source when perfluoroalkyl or polyfluoroalkyl substances exceed maximum contaminant level.

This bill requires New Jersey's Department of Environmental Protection (DEP) to study alternative drinking water sources when perfluoroalkyl or polyfluoroalkyl substances (PFAS) exceed legal safety limits. The DEP must identify available water supply options for public community water systems and gather input from water providers, experts, and the public within one year. The study will result in a report with findings and recommendations for potential policy changes, to be submitted to the Governor and Legislature. If the report is not completed on time, the DEP commissioner must explain delays to legislative committees. The bill directly affects public water systems that may need to switch sources during PFAS exceedances.
