(Reuters) – The contamination of U.S. drinking water with man-made “forever chemicals” is far worse than previously estimated with some of the highest levels found in Miami, Philadelphia and New Orleans, said a report by the Environmental Working Group (EWG) today.
The chemicals, resistant to breaking down in the environment, are known as perfluoroalkyl substances, or PFAS. Some have been linked to cancers, liver damage, low birth weight and other health problems.
Of tap water samples taken by EWG from 44 sites in 31 states and Washington D.C., only one location, Meridian, Mississippi, which relies on 700 foot (215 m) deep wells, had no detectable PFAS. Only Seattle and Tuscaloosa, Alabama had levels below 1 part per trillion (PPT), the limit EWG recommends.
The EPA has known since at least 2001 about the problem of PFAS in drinking water but has so far failed to set an enforceable, nationwide legal limit. The EPA said early last year it would begin the process to set limits on two of the chemicals, PFOA and PFOS.
