CNN: Study: Public water supply is unsafe for millions of Americans



PFASs seem to be everywhere. They are found “in wildlife and human tissue and bodily fluids all over the globe,” explained Arlene Blum, a co-author of the new study and executive director of Green Science Policy Institute. A chemist, she spearheaded a 2015 statement signed by 200 international scientists to urge restricted use of PFASs. For their new study, Hu, Blum and their colleagues examined more than 36,000 water samples collected by the Environmental Protection Agency between 2013 and 2015. The researchers discovered that 66 public water supplies serving 6 million Americans had at least one water sample that measured at or above the EPA recommended safety limit of 70 parts per trillion for perfluorooctanesulfonic acid and perfluorooctanoic acid, two types of PFASs. Newark, Delaware, and Warminster, Pennsylvania, showed particularly high concentration levels.
