New legislation has been introduced in Pennsylvania that would nearly eliminate the cancerous forever chemicals, per- and polyfluoroalkyl substances (PFAS) from the state's drinking water supply.

The bill's newly proposed regulation would cut the amount of the chemical down to 10 parts per trillion. It's significantly stricter than the current federal guideline of 70 ppt, and stricter than the 14 ppt first proposed a year ago by the Pennsylvania Department of Environmental Protection.

"Every Pennsylvanian has a constitutional right to clean drinking water and should not fear that something so basic and necessary to their life is slowly poisoning them," State Rep. MaryLouise Isaacson (D-Philadelphia) wrote in a co-sponsorship memorandum.

President Joe Biden's administration proposed the even stricter standard of 4 ppt this month (read “U.S. EPA Proposes New LOWER PFAS Levels for National Primary Drinking Water Regulation”), but there's no guarantee it will be approved.
