FINAL FIFTH FIVE-YEAR REVIEW REPORT FOR SACRAMENTO ARMY DEPOT SACRAMENTO, SACRAMENTO COUNTY, CALIFORNIA
U.S. Department of the Army, 162 pp, 2018

The Sacramento Army Depot (SAAD) opened in 1942 as an electronics maintenance facility primarily responsible for equipment receipt, storage, issue, repair, and disposal. Historical activities resulted in soil (metals, pesticides, PCBs, PAHs, VOCs, and SVOCs) and groundwater (VOCs) contamination. The site consists of three Operational Units: the South Post Burn Pits/Corrective Action Management Unit (CAMU) (OU1), South Post Plume (OU2), and Parking Lot 3 Plume (OU3). OU1 was remedied via excavation, capping, and soil vapor extraction, which removed ~138 pounds of VOCs (~98%) from the soil. OU2 groundwater was treated via extraction, ultraviolet light, and chemical oxidation through 120 wells placed 1981-2009. Groundwater in OU3 was treated using carbon adsorption at the wellhead and discharge to a sanitary sewer. OU1 has met all remediation goals, whereas the other two have not met Remedial Action Objectives and continue to be remediated. https://semspub.epa.gov/work/09/100009829.pdf
