Project Number: 2503-A10AF
Project Chief: Brian Hughes
Cooperators: U.S. Air Force, Aeronautical Systems Center
Period of Project: Began in 1995, now completed
THIS PROJECT HAS BEEN COMPLETED AND IS BEING ARCHIVED IN ITS FINAL CONFIGURATION
United States Air Force (USAF), Aeronautical System Center (ASC) is conducting environmental remediation activities at Air Force Plant 6 (AFP6) in Marietta, Georgia. These activities include addressing complex ground-water contamination, primarily the result of long–term manufacturing processes. Significant contamination of ground water by Dense Non-Aqueous Phase Liquids (DNAPL), that were employed as degreasing solvents, and metals above regulatory limits exist on and adjacent to USAF property. Remediation is extraordinarily difficult because of numerous historic point and non-point contamination sources, and most importantly by an extremely complex ground-water flow system, characterized by non-porous media flow in fractured and weathered metamorphic and igneous bedrock.
To support and enhance environmental remediation activities at AFP6, the U.S. Geological Survey (USGS) is conducting hydrogeologic investigations that characterize ground-water flow and contaminant movement in fractured crystalline rock. This includes providing technical guidance to ASC and assisting and advising ASC contractors, as well as conducting specific characterization and delineation efforts that directly support remediation.
