On September 29, 2022, The World Health Organization (WHO) published its draft guidance on perfluorooctanoic acid ("PFOA") and perfluorooctane sulfonate ("PFOS") in drinking water, which are the most widely studied of the per- and polyfluoroalkyl substances (PFAS). PFAS are a vast group of man-made chemicals found in many consumer products due to their desirable chemical properties. PFAS, however, resist degradation and, in some cases, have migrated into soil and groundwater, which created concern regarding its environmental and human health impact. As a result, a number of government agencies, including the US Environmental Protection Agency ("EPA") and a number of state governments, have issued recommendations and/or imposed maximum limits on PFAS in drinking water.
