Review Report: Feasibility Study Strategies and Remedial System Performance Improvement for the 200-ZP-1/PW-1 Operable Units at Hanford.

摘要

At the request of the U.S. Department of Energy, Headquarters Office of Environmental Management, the Office of Groundwater and Soil Remediation (EM-22), performed a Remediation System Evaluation (RSE) of the 200-ZP-1/PW-1 groundwater pump and treat (P&T) system, as well as the vadose zone Soil Vapor Extraction (SVE) system at the Hanford Site. These two systems are operated by Fluor Hanford (FH) to remove carbon tetrachloride (CT) from the vadose zone (i.e., SVE) and groundwater (i.e., P&T) under a Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) remedial action. DOE Richland (RL) is preparing a Feasibility Study (FS) for the Final Record of Decision (ROD) for the 200-ZP-1 OU. The RSE recommendations provide input to DOE to guide preparation, formulation, and optimization of the 200-ZP-1 and PW-1 draft FS submittals. The Review Team convened at Hanford from August 21-25, 2006, to conduct a site visit and inspection of the remedial systems under evaluation. Presentations were given by the 200-ZP-1/PW-1 FS and DOE Hanford teams on August 22-23, 2006.
