Biden Administration Sets First-Ever Limits on ‘Forever Chemicals’ in Drinking Water

The Biden administration on Wednesday finalized strict limits on certain so-called “forever chemicals” in drinking water that will require utilities to reduce them to the lowest level they can be reliably measured. Officials say this will reduce exposure for 100 million people and help prevent thousands of illnesses, including cancers.

The rule is the first national drinking water limit on toxic PFAS, or perfluoroalkyl and polyfluoroalkyl substances, which are widespread and long lasting in the environment.

Health advocates praised the Environmental Protection Agency for not backing away from tough limits the agency proposed last year. But water utilities took issue with the rule, saying treatment systems are expensive to install and that customers will end up paying more for water.

Water providers are entering a new era with significant additional health standards that the EPA says will make tap water safer for millions of consumers — a Biden administration priority. The agency has also proposed forcing utilities to remove dangerous lead pipes.
