Health assessment for Umatilla Army Depot, Hermiston, Oregon, Region 10. CERCLIS No. OR6213820917. Preliminary report
Technical Report
·
OSTI ID:5103860
The Umatilla Army Depot Site (UAS) is listed on the National Priorities List. The site covers 23 square miles and is located in Hermiston (Umatilla and Morrow Counties), Oregon. UAS is a storage depot for chemical warfare agents. Parts of the depot were contaminated with explosives as a result of past demilitarization and disposal operations. Preliminary on-site lagoon sampling results have identified 2,4,6-TNT (2,800 ppm in surface soil, 180 ppm in subsurface soil), RDX (350 ppm in surface soil, 260 ppm subsurface soil), dinitrotoluene (DNT) (10 ppm in surface soil) and tetryl (12 ppm in surface soil). Preliminary off-site ground water sampling results identified 2,4-DNT (trace to 400 ppb), 2,6-DNT (trace to 5 ppb), and 2,5,6-TNT (trace to 4,350 ppb). In addition, HMX (trace to 2,530 ppb) and RDX (trace to 7,480 ppb) were also identified in off-site ground water samples. The site is considered to be of potential public health concern because on-site employees may be exposed by direct contact to site-related contaminants in soil and possible ingestion of site-related contaminants that bioaccumulate through the food chain. It may be prudent to restrict areas of known contamination to post personnel.
