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 on Jan. 22 by an environmental watchdog group.
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.
