Toxic PFAS have likely contaminated roughly 57,412 locations across the U.S., according to a new study.
Those locations include certain industrial facilities, waste processing facilities, and places where firefighting foam containing PFAS (per- and polyfluoroalkyl substances) have been used, such as airports and military bases.
The study, published today in the journal Environmental Science & Technology Letters,found likely PFAS contamination sites in all 50 states. It is the first study to use existing scientific data on PFAS contamination to create a model that can predict locations where contamination is likely.
“PFAS contamination at these sites is not just possible, but probable,” Alissa Cordner, senior author on the paper and co-director of the PFAS Project Lab, told EHN. “Testing for PFAS is extremely expensive and requires a lot of time and technical capacity… One of our big goals is to help decision makers prioritize testing and remediation at these locations based on this high likelihood of contamination.”
