Research and regulatory attention to per- and polyfluoroalkyl substances (PFAS) has grown dramatically in recent years, yet data about PFAS-contaminated sites are incomplete. Researchers recently proposed a “presumptive contamination” model of identifying likely sources of PFAS exposure in the U.S.

Dr. Alissa Cordner and Dr. Kimberly Garrett, two of the co-authors of Presumptive Contamination: A New Approach to PFAS Contamination Based on Likely Sources, described the model used to identify and map contamination sites based on proximity to certain types of identified facilities. The analysis builds on state-based studies that use testing to identify suspected contamination sources, self-reported releases from industrial users, and studies that linked measured specific contamination with specific types of sites.
