The Umatilla Army Depot lagoons site is located in the center of the 19,700-acre U.S. Army Depot Activity, Umatilla (UMDA), 5 miles west of Hermiston, in Morrow and Umatilla Counties, Oregon. From the 1950's through 1965, UMDA operated an onsite explosives washout plant, which processed munitions to remove and recover explosives using a pressurized hot water system. An estimated 85,000,000 gallons of effluent were discharged to the lagoons during plant operations. The ROD provides a final remedy for the soil present at the lagoons. The primary contaminants of concern affecting the soil are inorganics and explosives, including DNB, 2, 4-DNT, HMX, NB, TNB, TNT, and RDX.
