Site Name   Memphis Depot
Site Location   Memphis, TN
Site Type   Federal Facility
Cleanup Program   Superfund Remedial
Entity Responsible for Cleanup   EPA
Project Name   Memphis Depot
Project Technology   Thermal Treatment (In Situ)
Scale   Full scale
Vendor   Not Specified
Project Status   Complete
Beginning of operational phase   05/01/2008
Project completion date   01/01/2009

Contaminants of Concern Trichloroethene
Media Type Soil
Extent/size of area of contamination   Eight separate source zones existed at the site. The combined area for treatment included 49,940 cubic yards of subsurface material to a depth of 30 feet below ground surface. The treatment system recovered approximately 12,500 pounds of contaminants.
Volume of Media Treated   49900 cubic yards
Description of geology/hydrogeology   Geology at the site consists of tight loess (silt/clay) above the water table.
Cleanup goals or remedial objectives   The remedial objective was to treat chlorinated solvents in soil to concentrations that are below the target remedial goals. The remedial goals for carbon tetrachloride, chloroform, 1,1,2,2-PCA, 1,2-dichloroethene, and trichloroethene were .215 mg/kg, .917 mg/kg, .0112 mg/kg, .755 mg/kg, and .182 mg/kg respectively.
Performance data available?   Yes
Summary and description of performance data   Soil sampling results indicated that the in situ thermal desorption system reduced contaminant concentrations to below 0.01 milligram/kilogram (mg/kg) in all eight source zone areas. Before treatment, these locations had chlorinated organic concentrations higher than 1,000 mg/kg.
Comments   Soil sampling results indicated that the in situ thermal desorption system reduced contaminant concentrations to below 0.01 milligram/kilogram (mg/kg) in all eight source zone areas. Before treatment, these locations had chlorinated organic concentrations higher than 1,000 mg/kg.
