"Pennsylvania has enacted a statewide drinking water limit on two forms of highly toxic chemicals, nicknamed "forever chemicals."

The rule, published earlier this month in the official register of state government agency actions, sets a limit of 14 parts per trillion for perfluorooctanoic acid and 18 parts per trillion for perfluorooctane sulfonic acid.

The rule applies to all 3,117 water systems, the Department of Environmental Protection said.

Both chemicals belong to the group of perfluoroalkyl and polyfluoroalkyl substances, known collectively as PFAS, which are used in products such as nonstick cookware, carpets, firefighting foam and fast-food wrappers."
