US drinking water may have double the PFAS reported

A new study set for publication Oct. 23 in Cell Reports Sustainability suggests that standard methods for reporting PFAS levels in U.S. drinking water could be underestimating the actual concentration by as much as half. PFAS, the man-made chemicals often called forever chemicals, are known to pose environmental and health risks. The model-based estimate indicates that the true extent of contamination in tap water could be significantly higher than what current monitoring data shows.

How much should current water testing methods change to catch hidden PFAS?
