10 toxic ‘forever chemicals’ found in Louisville, KY, tap water
News
22 Oct 2019 | EWG News
The highest level of any single PFAS detected in the EWG sample collected in Louisville was 22 ppt of a compound known as GenX. It is a replacement chemical for PFOA, which was used to make Teflon before U.S. manufacturers phased it out of production under pressure from the EPA. The EPA’s research has found that GenX is nearly as toxic as the PFOA it replaced, and DuPont, its original manufacturer, has provided test results to the EPA showing that GenX caused cancer in lab animals.
