LOW COST SOLIDIFICATION/STABILIZATION TREATMENT FOR SOILS CONTAMINATED WITH DIOXIN, PCP AND CREOSOTE
Bates*, E R., F. Akindele*, AND D. Sprinkle. LOW COST SOLIDIFICATION/STABILIZATION TREATMENT FOR SOILS CONTAMINATED WITH DIOXIN, PCP AND CREOSOTE. 94th Annual Conference of Air and Waste Management Association, Orlando, FL, 6/24-28/2001.
The USEPA's NRMRL conducted successful treatability tests of innovative solidification/stabilization (S/S) formulations to treat soils contaminated with dioxins, pentachlorophenol (PCP), and creosote from four wood preserving sites. Formulations developed during these studies were successful in reducing the mobility (leaching) of contaminants of concern by 95-99%. For one of these sites, the American Creosote Superfund site in Jackson, TN, the USEPA in cooperation with the State of Tennessee conducted a successful remediation of 45,000 cubic yards during 1998 and 1999. The costs to excavate, tratment, replace, and cap soil contaminated with dioxin, PCP, and creosote averaged $64/cubic yard (about $40/ton). Formulations, design, operations, performance specifications, and costs are presented in this paper.
