New testing by the Environmental Working Group has identified the presence of toxic fluorinated chemicals, broadly known as PFAS, in the tap water of dozens of cities across the U.S. where contamination was not previously known.
EWG, an advocacy organization that tracks environmental pollutants in consumer products, sampled water in 44 places between May and December 2019. The testing revealed the presence of so-called “forever chemicals” in 34 water systems, including in the Ohio cities of Columbus and Cincinnati, as well as in Pittsburgh, Pennsylvania. Previous testing from the group found 10 PFAS compounds in tap water in Louisville, Kentucky.
The so-called “forever chemicals” persist in the environment and in the human body and have been found in numerous water systems in the Ohio Valley. PFAS chemicals were used in flame-retardant foam sprays and in the manufacture of nonstick and stain-resistant products.
