Woodbridge Research Facility Remedial Investigation/Feasibility Study; Focused Feasibility Study for Operable Unit Three

摘要

Operable Unit 3 (OU3) at the Woodbridge Research Facility (WRF) has been defined as the Main Ditch (AREE 22) and the area between the northern boundary of the Main Compound and the Main Ditch (portions of AREEs 11 and 17). This report summarizes the site history, current conditions, and environmental data associated with OU3. Human Health and Ecological Risk assessments are presented. General response actions, technology types, and process options appropriate for the remediation of sediment are identified as well as proposed elements for the implementation of institutional controls for the OU. Process options are screened and assembled into six 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.
