EPA says it has a plan to address PFAS in drinking water - and will announce it in Philly tomorrow by Laura McCrystal an

The EPA will travel to Philadelphia and announce plans to regulate how much PFAS can be in drinking water. The chemicals, used in firefighting foams on military bases, have affected drinking water nationwide.

Activists, residents, and state agencies have pushed for action from the EPA on the chemicals, which in 2014 were widely discovered to have leaked into water supplies near military bases nationwide, including sites in Willow Grove and Warminster.

Used in firefighting foams by the military — as well as contained in many common household products — PFAS, or per- and polyfluoroalkyl substances, have been linked to health issues including cancer and reproductive problems.
