Superfund Record of Decision (EPA Region 9): Sacramento Army Depot, Operable Unit 4, Sacramento, CA. (Third remedial action), September 1992
The 485-acre Sacramento Army Depot (SAAD) site is a military facility in Sacramento County, California. Land use in the area is predominantly commercial and light industrial, with wetlands in the vicinity of several oxidation lagoons. The estimated 56,398 people who live within 2 to 3 miles of the site use municipal water as their drinking water supply. From 1950 to 1972, the lagoons received mostly industrial waste water from metal plating processes and domestic wastewater. The selected remedial action for the site includes excavating and treating approximately 15,500 cubic yards of contaminated soil onsite using soil washing; dewatering and then backfilling the treated soil onsite in the excavation areas, and storing the rinsate temporarily in onsite holding tanks for recycling; treating rinsate from the treatment process using chemical precipitation, clarification/flocculation, and chemical coagulation to remove metals, prior to discharge into the sanitary sewer; dewatering the sludge containing the precipitated metals, and stabilizing this if necessary, followed by disposal in an RCRA landfill or recovery at an offsite reclamation unit. The estimated present worth cost for this remedial action is $5,020,000. There are no O M costs associated with the remedial action.
