EPA says PFAS, 'forever chemicals,' riskier than first thought and it will offer $1 billion to help address the problem

The Environmental Protection Agency warned Wednesday that widely used "forever chemicals" in drinking water are more dangerous than previously thought, and advised local governments to install water filters or at least warn residents of contamination, Dino Grandoni reports for The Washington Post. The advisories are non-binding, since the federal government doesn't currently regulate polyfluoroalkyl and perfluoroalkyl substances, or PFAS. However, EPA plans to propose mandatory standards for the two most common types of PFAS this fall. 

"Once finalized, water utilities will face penalties if they neglect to meet them. The advisories will remain in place until the rule comes out," Grandoni reports. "EPA also said Wednesday that it is offering $1 billion in grants to states and tribes through the bipartisan infrastructure law to address drinking-water contamination."

PFAs were invented in the 1940s and are used for nonstick cookware, flame-retardant equipment, water-repellent fabrics, fast-food wrappers and more. The chemicals have been linked to health risks for some time, but recent studies about the most common PFAS show that "lifetime exposure at staggeringly low levels of 0.004 and 0.02 parts per trillion, respectively, can compromise the immune and cardiovascular systems and are linked to decreased birth weights," Grandoni reports.
