USEPA Announces Final Drinking Water Standards For Six PFAS

In much anticipated news for followers of PFAS, or so-called "forever chemicals," USEPA announced today final, enforceable drinking water standards (MCLs) for six PFAS, including PFOS and PFOA at 4 parts per trillion. EPA "expects that over many years the final rule will prevent PFAS exposure in drinking water for approximately 100 million people, prevent thousands of deaths, and reduce tens of thousands of serious PFAS-attributable illnesses." This will be extremely impactful for many water suppliers across the United States, including in California, which is in the process of developing its own MCLs for PFAS (that by law will need to be at least as stringent as federal standards).
