The chemicals produced and disposed of during these operations include napalm, white phosphorous, solvents, and military unique chemical agents. Incidental disposal of contaminated test material and excess chemicals occurred throughout the Edgewood Area. The exact quantities of chemicals used, manufactured, and disposed are not known. Probable sources and locations of contaminants were identified in an Environmental Survey conducted by the Army Environmental Center and many areas of groundwater contamination were identified for further study by a U.S. Geological Survey investigation. Facility Assessment identified SWMUs.
Remedial investigations are underway or completed at all of the study areas.
Monitoring wells have been installed along the facility boundary to further define the hydrologic conditions at Edgewood and potential off-site impacts. Threats of exposure to contaminants have been reduced by initial actions taken. At Graces Quarters, the extent of groundwater contamination is under investigation. A removal action to address unexploded ordnance and potential chemical warfare materials along the Lauderick Creek Boundary is in the planning stage. Remedial Action is underway at many sites.
