Abstract: Abstract: The U.S. Army Urnatilla Depot Activity (UMDA) is a 19,700-acre (7,975.70-ha) military reservation that was established as an ordnance depot in 1941. The primary mission of the UMDA is to store, preserve, and perform minor maintenance on conventional and chemical munitions. The UMDA also stores strategic materials for the Defense Logistics Agency and reserve equipment withdrawn from normal service. Two sites were selected at the UMDA to determine if solidification/stabilization (SIS) could be used for the cleanup of these sites. The two sites are identified as Operable Unit 5 (OU-5) and the Ammunition Demolition Area (ADA) (OU-4). Five soils were chosen for evaluation using current S/S technology. The five sites were identified as Sites 22 and 36 from the OU-5 and Sites 15. 19, and 31 from the ADA. The soils from Sites 22 and 36 were contaminated with heavy metals, and Sites 15, 19, and 31 were contaminated with heavy metals and explosive compounds. All soils were subjected to physical and contaminant leach tests prior to S/S being applied to the soils. This information gives basic engineering properties of the soils and background data for comparison of the treated soils. Chemical data of the soils indicated that Soils 15 and 19 had the highest concentration of metals and explosive compounds found in the soils evaluated. Soils 22 and 36 had elevated concentration of heavy metals, while Soil 31 was the least contaminated, indicating low levels of heavy metals and no explosives.
