The New Jersey Department of Environmental Protection (NJDEP) will set formal Maximum Contaminant Levels (MCLs) for perfluoroctoanic acid (PFOA) and perfluorononanoic acid (PFNA). The move, which requires statewide testing of public drinking water systems, is based on the New Jersey Drinking Water Quality Institute’s recommended drinking water standards of 14 parts per trillion for PFOA and 13 parts per trillion for PFNA. Previously, PFOA was subject to a non-binding “guidance level” level of 40 ppt. New Jersey becomes the first state to set MCLs for these contaminants, which, according to a growing body of evidence, may impact liver and immune system function. For the press release, click here.
