CHRISMAN RD
The 448-acre Tracy Defense Depot site was an Army Supply Depot from 1942 to 1963 when it was turned over to the Defense Logistics Agency. Operations at the site include repacking leaking chemical containers, fumigating shipping materials, maintaining vehicles, painting, storing chemicals, preserving metal parts, operating chemical and photographic laboratories, storing and mixing pesticides, and storing and treating liquid and solid wastes. Liquid waste treatment and storage areas include an unpaved storage area, two unlined sewage effluent ponds, two abandoned sewage lagoons, two lined industrial wastewater ponds, an abandoned paint spraying/stripping rinse water pond, an abandoned trench where 150 drums of waste oil were buried, an unlined pond for holding stormwater, an abandoned pesticide disposal trench, an abandoned area where substantial amounts of formaldehyde were buried, and aboveground and underground waste tanks. Hazardous materials, including solvents, radioactive materials, medical supplies, and solid and liquid chemicals, were disposed of in three burn pits. Former solid waste treatment and storage areas included a fill area where food items were buried, a fill area where construction material was buried, and three impoundments where wastes containing mercury phosphate compounds were stored. Currently, all solid hazardous waste is hauled off site to federally-approved disposal facilities. The shallow aquifer below the site is contaminated with volatile organic compounds (VOCs) which are captured by a groundwater pump and treat system. Approximately 25,000 people live within three miles of the site. A Record of Decision (ROD) was finalized in August 1993 which addresses three major VOCs in groundwater, i.e., TCE, PCE and DCE.
