Assessing PFAS exposure in Rocky Mountain elk (Cervus canadensis nelsoni) populations adjacent to the former Rocky Flats nuclear site: A preliminary analysis.

ABSTRACT: The Rocky Flats National Wildlife Refuge is located west of Denver, Colorado, USA along the central Front Range of the Rocky Mountains. The wildlife refuge property includes a former U.S. Department of Energy nuclear weapons facility, hereafter "the former Rocky Flats site." Owing to the storage and use of aqueous film forming foam (AFFF) at the on-site fire department, industrial areas of the former Rocky Flats site has detectable concentrations of per- and polyfluoroalkyl substances (PFAS) in groundwater (range perfluorooctanesulfonic acid [PFOS]: not detected [ND] [<0.75]-350 ng/L, perfluorooctanoic acid [PFOA]: ND [<0.55]-160 ng/L) and surface water (range PFOS: 1.9-18 ng/L, PFOA: ND [<0.55]-13 ng/L). AFFF is a known source of PFOA and PFOS contamination in the environment. PFAS are a
