摘要

The purpose of the Southern Study Area (SSA) Report is to present the Army's Remedial Investigation (RI) results for the southern portion of Rocky Mountain Arsenal (RMA). This document is a formal RI product in accordance with the proposed Federal Facilities Agreement and Settlement Agreement (1988), the RMA Technical Program Plan (TPP) (PMO, 1988/RIC 88131R01), and the June 1985 U.S. Environmental Protection Agency (EPA) RI Guidance Document. The seven completed RI Study Area Reports (SARs), along with the RI media reports for air, biota, buildings, and water, fulfill the requirements of defining the nature and extent of contamination, and completing a comprehensive RI for the On-post Operable Unit of RMA as required by the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), the Superfund Amendments and Reauthorization Act (SARA), and the National Contingency Plan (NCP). The SSA Report integrates known historical information, the results of previous investigations, and the current RI programs for buildings, soil, surface water, groundwater, biota, and air to present an overall environmental contamination assessment of the study area as required under Contract Numbers DAAA15-88-D-0024. The SSA Report represents Volume VI of the overall RMA Remedial Investigation.
