Operable Unit One (OUl) at the Woodbridge Research Facility (WRF) has been defined as the area encompassing AREEs 1 through 6B (former dumps) and AREE 7 (former Pistol Range). A Focused Feasibility Study, has been conducted to identify and screen remedial alternatives for OUl, to address, contaminated groundwater, surface soil, subsurface soil, and sediment detected at AREEs associated with OU1. This report summarizes the history, current conditions, and environmental data. Human health and ecological risk assessments are presented. General response actions, technology types, and process options appropriate for the remediation of contaminated media are identified. Process options are screened and assembled into five alternatives. Each alternative is evaluated in detail using the nine criteria identified in the NCP (40 CFR 300.430(e)). The report concludes with a comparison, of the remedial options under consideration.
