OSTI ID:10117032

This Technology Demonstration Assessment Report (TDAR) was developed to evaluate and recommend the most feasible approach for cleanup of contaminated Minford soil in the vadose zone and to summarize closure activities at the Portsmouth Gaseous Diffusion Plant (PORTS) X-231B Oil Biodegradation Plot (X-231B). The X-23 IB site, consisting of a north and south area, is oriented on a north-south axis. The north and south areas measure 265 ft by I 10 ft and 100 ft by 70 ft, respectively. The X-231B Technology Demonstration (TD) Project was initiated during fall 1990 to identify and evaluate emerging technologies which could provide cost effective and feasible in situ soil treatment. The four technologies plus the Contingent Design evaluated were: In situ Soil Mixing with Solidification/Stabilization; In situ Soil Mixing with Isothermal Vapor Extraction; In situ Soil Mixing with Thermally Enhanced Vapor Extraction; In situ Soil Mixing with Peroxidation Destruction; Center-line Trench Drain - Contingent Design.
