The Environmental Protection Agency finalized a rule on Wednesday that will limit the amount of “forever chemicals” in public water utilities.

The rule will be the first to limit the amount of PFAS, or perfluoroalkyl and polyfluoroalkyl chemicals, in drinking water, according to the Associated Press. PFAS do not degrade and can negatively affect the public’s health, according to the report, and was announced as being part of President Joe Biden’s “cancer moonshot” initiative.
