New testing of bottled water in the United States has revealed taints of per- and polyfluoroalkyl substances (generally, PFAS). The “forever chemicals” have been widely used for decades and have been found in almost everything from frying pans to, notably, firefighting foam. The chemicals have leached into groundwater and have been found in almost all people tested. Research into health impacts is still evolving but it is known that PFAS are harmful to pregnant women and young children.
