A recent publication in Science by Andrea Tokranov, Class of 2012, presents a national predictive model for assessing the level of "forever chemicals" (PFAS) in groundwater at the depths of drinking-water supplies across the United States. The study suggests that up to 95 million people may unknowingly rely on groundwater contaminated with PFAS. Since PFAS analysis is costly, the model aims to help direct resources to high-risk areas.
