Why are LUCs used at Superfund sites?
LUCs are used at Superfund sites until final, unrestricted site use conditions are in place. LUCs are also used when final remedial action encapsulates residual contamination. LUCs at Superfund sites supplement other remedial actions such as treatment, and encapsulation of contaminants and are rarely used as the sole remedy. EPA guidance on Superfund remedial action advises Superfund site managers to use multiple types of LUCs to ensure long-term protectiveness of remedial action.
