Phys.org / Faster lower-cost PFAS testing could reshape how US drinking water is monitored

A new investigation from the University of Kansas improves detection of PFAS, a family of so-called "forever chemicals" in drinking water supplies. The method, which can measure trace pollution levels of PFAS in water more ...
