On Wednesday, the Environmental Protection Agency (EPA) announced plans to weaken limits on certain harmful “forever chemicals” (PFAS) in drinking water, just a year after implementing the first national standards aimed at reducing PFAS exposure. These chemicals, known for their resistance to breakdown, have contaminated air, water, and soil since their introduction decades ago, primarily by companies like 3M and Chemours. Their widespread use in nonstick cookware, firefighting foams, and waterproof clothing has raised significant health concerns, including links to kidney disease, low birth weights, high cholesterol, and certain cancers.
Despite the initial regulations set by the Biden administration to limit two common types of PFAS—PFOA and PFOS—to 4 parts per trillion, the EPA now intends to rescind limits on three lesser-known types of PFAS and extend the compliance deadline for PFOA and PFOS to 2031. This decision has generated mixed reactions; while some water utilities welcome the extension to better prepare for compliance, environmental advocates argue that the EPA lacks legal authority to weaken these regulations under the Safe Water Drinking Act. They express concerns that these rollbacks could harm public health and undermine efforts to ensure water safety.
Industry representatives have had varied responses, with some questioning the scientific basis for the stricter Biden-era rules while others emphasize the need for affordable compliance measures. Overall, while the EPA maintains current limits on PFOA and PFOS, the changes signal a shift away from stringent oversight on PFAS, raising fears among health advocates about the potential risks to communities nationwide.
