New PFAS chemical contamination discovered in New Jersey
News
4 Jun 2020 | The Intercept
The recently identified chemicals is known only as “Solvay’s compound” which is a replacement for the PFNA, a close relative of PFOA. Previously, 83 wells around the site have been found to be contaminated with both PFNA and PFOA. Elevated levels of PFNA were found in people living near the plant, with one person’s blood level reaching 63 times the national average.
