Toxic chemicals found in nonstick cooking pans and other household items have contaminated more than 600 water sources across at least 43 states, according to a new report, with Michigan by far the most impacted. The findings underscore the wider water crisis facing the United States and are likely to increase pressure on the Environmental Protection Agency (EPA) to enact stricter limits on per- and polyfluoroalkyl substances (PFAS), toxic chemicals that can increase the risk of cancer and other severe health problems. New analysis published Monday by the Environmental Working Group (EWG) and Northeastern University finds that 610 water sources across the country contain PFAS. The water systems include drinking water sources that serve upwards of 19 million people, along with military and industrial sites, dumps, and airports. PFAS itself is found in everything from firefighting foam to rain jackets. To view the full article visit Think Progress.
