Superfund record of decision (EPA Region 8): Ellsworth Air Force Base, Operable Unit 4, Landfill No. 3 Area, SD, May 16, 1995. Final report
The ROD is for an interim remedial action (IRA) at OU-4 and is the second ROD for EAFB. The scope of the IRA is to reduce the immediate risks posed by the contaminants in ground-water by preventing further transport off-Base and by removing contaminated ground-water which is already off-Base. The IRA includes construction of ground-water wells downgradient of Landfill 3 and wells near the Base property boundary. These wells will be operated to contain the contamination. In addition, the wells will be constructed in the most highly contaminated areas of the off-Base plume and operated to contain and remove this area of off-Base ground-water contamination. Implementation of the IRA will result in partial restoration of the shallow ground-water downgradient of Landfill 3.
