New Jersey Publishes Formal Stringent Drinking Water Standards for PFOA and PFOS

On June 1, 2020, the New Jersey Department of Environmental Protection (DEP) officially published health-based drinking water standards for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS). These chemicals have received serious attention from the environmental community in the last several years due to increasing science that has confirmed the harmful impact of PFOA/PFOS on human health and the environment. These new more stringent rules, published in the New Jersey Register, set maximum contaminant levels (MCLs) at: 14 parts per trillion for PFOA and 13 parts per trillion for PFOS. The DEP also added PFOA and PFOS to the state’s list of hazardous substances. Site remediation activities and regulated discharges to groundwater of PFOA and PFOS will now have to comply with these new standards. These new formal standards establish a regulatory framework that will provide consistency in remediation activities statewide. It is important to note that PFOA and PFOS are just two of potentially thousands of per- and polyfluoroalkyl substances (or PFAS). To date Vermont and New Hampshire are the only other two states to set MCLs for PFAS. New York is working on similar standards. New Jersey issued a standard of 13 parts per trillion for perfluorononanoic acid...
