Pennsylvania and Delaware have joined a growing list of states moving to set enforceable limits in drinking water for two “forever chemicals,” which have been linked to health concerns, including cancer.
The two states have taken steps to establish state-specific maximum contaminant levels for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS). Those compounds are among the most thoroughly studied of a group of highly persistent chemicals called per- and polyfluoroalkyl substances, or PFAS. Studies have shown that exposures to certain PFAS can cause a variety of health problems, including decreased fertility, developmental delays in children and reduced immunity to infection.
