Hydrological units with detectable PFASs

Poly- and perfluoroalkyl substances (PFASs) are everywhere, and they are persistent. Exposure to these compounds has been linked to several adverse health effects, so identification of especially vulnerable populations is urgently needed. Hu et al. performed a spatial analysis of PFASs in U.S. drinking water. Higher reported PFAS levels were associated with manufacturing sites and military fire training facilities. In total, water supplies serving 16 million residents contained PFASs at or near minimum reporting levels. Because many U.S. residents rely on undersampled private wells or small public water supplies, exposure from drinking water remains unknown for nearly one-third of the U.S. population.
