In Texas, 49 public water utility systems have reported surpassing the U.S. Environmental Protection Agency’s first-ever limits for five “forever chemicals” in drinking water, according to data submitted to the federal agency.
Experts say there are likely more since not all water systems have submitted their data.
PFAS, or perfluoroalkyl and polyfluoroalkyl substances, are widespread and long lasting in the environment. They are called “forever chemicals” because they don’t break down and can persist in water and soil, and even human blood indefinitely. The chemicals have been used since the 1940s to repel oil and water and resist heat. They have been included in thousands of household products from nonstick cookware to industrial products like firefighting foam.
There are more than 12,000 types of individual forever chemicals, but new EPA standards announced last week set new limits for five of them: PFOA and PFOS have a limit of 4 parts per trillion while PFHxS, PFNA, and HFPO-DA have a limit of 10 parts p
