A recent study examining the long-term presence of per- and polyfluoroalkyl substances (PFAS) in human blood following long-term exposure to the chemicals after a paper mill was linked to local drinking water contamination found that women in the low-exposure study group were more successful at eliminating the PFAS from their bodies than men in the same group.

The Yorba Linda, Calif., water district has the country’s largest PFAS treatment facility of its kind. The drinking water it delivers to customers is free of these unwanted “forever chemicals.”
