Superfund record of decision (EPA Region 7): Cornhusker Army Ammunition Plant, Operable Unit 1, Hall County, Grand Island, NE, September 29, 1994

Technical Report ·
OSTI ID:63775
The decision document presents the selected interim remedial action for the groundwater operable unit at the Cornhusker Army Ammunition Plant (CAAP). Operable Unit One encompasses the explosives groundwater plume(s), both on-post and off-post. Explosives of concern in the contaminant plume include RDX, TNT, HMX, and their decomposition products. The objective of the interim action is to contain the plume and prevent further migration of contaminants, and does not encompass full restoration of the plume of contaminated groundwater. The recommended alternatives provide an approach to containing and removing contaminant mass from the groundwater plume. This approach will control further migration of the plume and reduce the levels of the contamination in groundwater.
