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.

Concerns rise over tainted sewage sludge spread on croplands
News
12 Sep 2019 | Associated Press
Several states are examining sewage sludge for PFAS contamination and assessing potential dangers. Maine has enacted a nonbinding advisory level for PFAS in sludge and New Hampshire is working with the U.S. Geological Survey on a soil study whose results will help them set a standard. Maine also found most biosolids from more than 30 wastewater treatment plants were above the state's advisory level while neighboring New Hampshire detected PFAS in tests of sludge from two dozen permit holders. Neither state found traceable levels of PFAS in the milk tested. Based on sludge tests at 41 plants, Michigan ordered several to stop distributing it to farms.
