    Stage of Clean-up: Construction Underway

    California Conditions at proposal (July 14, 1989): Hunters Point Annex of Treasure Island Naval Station, formerly the Hunters Point Naval Shipyard, encompasses 936 acres (522 acres dry land and 414 acres submerged in San Francisco Bay) in the southeast corner of San Francisco, California. Established in 1869, the shipyard was the first privately owned dry dock on the Pacific Coast. The Navy first used the installation in 1919 to construct, maintain, and repair ships, and in 1939 purchased it from California Dry Dock Co. Triple A Machine Shop leased the facility from the Navy during 1976-87, subleasing numerous buildings to private tenants. The Navy regained possession of the shipyard from Triple A in 1987, but continues the subleasing. Operations of the facility over many decades generated a wide variety of solid and liquid wastes, including paints, solvents, fuels, acids, bases, metals, PCBS, and ASBESTOS. Hunters Point Annex is participating in the Installation Restoration Program (IRP), established in 1978. Under this program, the Department of Defense seeks to identify, investigate, and clean up contamination from hazardous materials.  More...

  • Threats and Contaminants
    Groundwater, sediments, soil, and surface water are contaminated with fuels, pesticides, HEAVY METALS, PCBS, and VOLATILE ORGANIC COMPOUNDS (VOCS). Soil also contains ASBESTOS. A landfill located on Parcel E also contains RADIUM dials. People who accidentally ingest or come in direct contact with contaminated soils, sediments, surface water, or groundwater may face a health risk. Potential threats may also be presented by off-gas from VOCS, particularly VINYL CHLORIDE, present in hot spots in soil and groundwater.
