[18] Due to the large number of PFAS, it is challenging to study and assess the potential human health and environmental risks; more research is necessary and ...
Among the places where data is available, USA TODAY’s analysis shows large cities have exceeded PFAS limits at higher rates than smaller places. About a third of water systems serving over ...
Long-chain PFAS chemicals perfluorooctane sulfonic acid, or PFOS, and perfluorooctanoic acid, or PFOA, are among the most studied of the nearly 15,000 types of PFAS used by industry.
