Title: Sitewide biological risk assessment Eielson Air Force Base, Alaska: Risks to terrestrial receptors from diverse contaminants

Abstract

Eielson Air Force Base (AFB) is located southeast of Fairbanks, Alaska. Eielson AFB was listed by the US Environmental Protection Agency on the National Priorities List with a total of 64 potential terrestrial and aquatic source areas. Contaminants of concern include fuel and fuel components, pesticides, polychlorinated biphenyls (PCBs), and lead. As part of the remedial investigations of these sites, a biological risk assessment (BRA) was conducted to estimate the risk of ecological effects on terrestrial receptors posed by contaminants in the Eielson environment. There are 32 mammal species, 117 bird species, 17 fish species, and 1 amphibian species known to inhabit Eielson AFB and vicinity. The BRA screened source areas based on completed biological exposure pathways, selected receptors for analysis, estimated exposure of receptors to contaminants, and compared these exposures to known toxicological effects. Lower Garrison Slough and Flightline Pond posed a substantial risk for shrikes and goshawks. Ingestion of PCBs constituted the primary pathway/contaminant combination contributing to this risk. The effects of the various sources of uncertainty in the ingestion exposure calculations for these sites were evaluated in a probabilistic risk assessment using Monte Carlo methods. There was an 11% risk of reproductive effects from PCBs for goshawksmore » feeding from Flightline Pond and a 25 % risk from lower Garrison Slough. There was an 81 % risk of reproductive effects from PCB exposure for shrikes feeding near lower Garrison Slough.« less
