The 632-acre Memphis Defense Depot (Depot) is located in Memphis, Tennessee. It is a former warehousing and distribution center for the U.S. military where waste handling and disposal occurred. Releases of chemicals from the wastes that were released on site resulted in contaminated soil, groundwater, surface water and sediment. In 1992, EPA placed the site on the Superfund program�s National Priorities List (NPL). EPA, the Tennessee Department of Environment & Conservation (TDEC) and the U.S. Department of Defense (DoD) have undertaken investigations and cleanup actions to protect human health and the environment.
Significant progress in reducing contaminant concentrations in groundwater and soil have been made. The parties are currently evaluating additional cleanup activities to prevent migration and restore groundwater. No one at the Depot or off site is exposed to the contaminated groundwater. The DoD, EPA and TDEC continue to ensure the protectiveness of the site�s remedy through long-term monitoring of groundwater, land use controls and the required Five-Year Reviews of remedy performance and overall site protectiveness.
