Abstract : This feasibility study (FS) for the Explosives Washout Lagoons (Site 4) Soils Operable Unit at the U.S. Army Depot Activity at Umatilla (UMDA) has been prepared to evaluate potential remedial alternatives for mitigating soil contamination at the site. The FS provides a summary of remedial investigation information; a summary of the baseline risk assessment prepared by Dames a Moore; remedial action objectives; identification and screening of potentially viable technologies; and a detailed evaluation of alternatives assembled from the most promising technologies. The alternatives evaluated in detail are No Action, excavation followed by incineration and excavation followed by composting. Incineration is a proven method of destroying explosives contaminants with an effectiveness greater than 99.99 percent.
