Technical Report ·
OSTI ID:241289

This decision document presents the selected remedial action for the Velsicol Hardeman County Landfill, Operable Unit No. 2, in Toone, Hardeman County, Tennessee. The remedy includes capping the 27-acre landfill with a RCRA composite cap to reduce infiltration of surface water through the waste and contaminated soil. The RCRA composite cap consists of: scarifying existing vegetative cover and recompacting; a 40-mil high density polyethylene (HDPE) synthetic liner or equivalent, placed over the recompacted clay surface; a sand drainage blanket with a minimum hydraulic conductivity of 1 x 10-3 cm/sec placed over the liner to provide lateral drainage; the sand will be covered with a filter fabric and a layer of common fill and topsoil; a vegetative cover will be established to prevent erosion of the fill and topsoil materials; and routine monitoring of the RCRA cap in order to maintain the integrity of the cap.
