SERDP; Hunt Valley, Maryland; Investigating Potential Risk to Threatened and Endangered Species from PFAS on Department of Defense Sites
Risk estimation for eaglets from nearby PFOS-contaminated bayou.
EA conducted research funded under SERDP to investigate potential risks to threatened and endangered species from PFAS on DoD sites. Our researchers used spatial analysis of DoD sites with known AFFF releases and interpolation methods of PFAS migration through habitat of threatened and endangered species to determine PFAS exposure potential to wildlife receptors. Using this information, EA developed a framework to prioritize wildlife receptors for PFAS risk concerns with the goal for installation natural resource managers to quickly and cost effectively determine if there is probable risk to threatened and endangered species on PFAS-contaminated installations. Our scientists also developed probabilistic PFAS exposure assessment models for avian and reptile taxa to provide the most realistic PFAS risk scenarios.
