Investigating Potential Risk to Threatened and Endangered Species from Per- and Polyfluoroalkyl Substances (PFAS) on Department of Defense (DoD) Sites
Abstract
Federal and State threatened and endangered fauna species occupy many Department of Defense (DoD) sites. The diversity of the species is great ranging from invertebrates to higher trophiclevel predators. Importantly, many DoD sites are also impacted by historical activities that result in chemical contamination. One of those activities was widespread use of Aqueous Film Forming Foams (AFFF) to suppress fires and in fire training exercises that has resulted in Per- and Polyfluoroalkyl Substances (PFAS) distributed in many environmental compartments. A species-specific exposure potential to PFAS was developed to provide an initial screen of impacted habitat using spatial analysis. Protected species (or taxa) can then be ranked by those that occupy the greatest proportion of PFAS impacted habitat. Those species may be prioritized for hazard and/or risk assessment. Here, we carry two species (northern pine snake and bald eagle) through to develop a probabilistic risk framework on site specific PFOS concentrations.
