The coordinates for the Site are 37°49'39" North and 122°31'24" West. The site was used for housing, administration, and an anti-aircraft artillery Nike Battery. The Site is now the Fort Barry unit of the GGNRA. The two enlisted barracks are now housing an art center and hostel. The family quarters are still in use as private residences. Battery Wallace is used as an NPS warehouse. The post chapel has been converted to a visitor center. Former SF-88A has been converted to a conference center, and is used by the Young Men's Christian Association (YMCA). Former SF-88L has been fully restored by the NPS as an exhibit area open for guided tours. (Source: U.S. Army Corps of Engineers) « see less

We haven't independently confirmed the location of every site. If you notice a site placed at the incorrect location, please contact us.
Not all sites in the DOD data include location information, so there may be sites listed below that are missing from the map. The risk level of a site refers to a relative risk assessment made by the DOD to prioritize the cleanup of sites.
2 Active Sites
Sites where military cleanup actions are still ongoing. The risk level of a site refers to a relative risk assessment made by the DOD, which prioritizes the cleanup of sites that pose greatest threat to safety, human health, and the environment.

Contaminated Areas
Soil: High Risk
In 2010, soil samples were collected for XRF quantitative analysis to define lateral and vertical extent of lead contamination. Boundaries were defined. Highest Pb concentrations at fence backstops on surface down to depth of 10 ft. Extent of lead contamination isolated to firing berms and backstop area. Vertical extent no greater than 2-3 ft on firing berms and no greater than 10 feet on first berm in backstop.

Contaminated Areas
Groundwater: Low Risk
GW data collected at source showed trace levels of toluene and xylenes. GW data collected downstream were ND indicating very little movement towards Rodeo Lagoon. GW data collected downgradient shows no impact and the GW is not considered a potential source of drinking water.
Contaminants: Toluene 0.1 ug/L Xylenes 0.41 ug/L
Soil: Low Risk
Most of the contamination found has been in relation to the removal of UST's and AST's. TPH contaminated soils at depths below 10 ft. Soil contamination isolated to soil band of 10-20 feet bgs. Collection of downgradient water data shows that there is no impact to aquatic receptors in Rodeo Lagoon.
Contaminants: sec-Butylbenzene 0.00069 mg/kg Mercury (methyl) 0.00071 mg/kg Cumene (isopropylbenzene) 0.0015 mg/kg Vinyl chloride (child/adult) 0.0016 mg/kg Toluene 0.0037 mg/kg Benzene 0.0042 mg/kg 1,1-Dichloroethane 0.0063 mg/kg 1,2,4-Trimethylbenzene 0.0065 mg/kg Tetrachloroethylene (PCE) 0.018 mg/kg Polychlorinated biphenyls (PCBs) 0.027 mg/kg Ethylbenzene 0.033 mg/kg Cadmium and compounds 0.43 mg/kg Beryllium and compounds 0.51 mg/kg Xylenes 0.517 mg/kg Selenium 1.9 mg/kg Naphthalene 3.5 mg/kg Molybdenum 5.0 mg/kg Arsenic 10.0 mg/kg Cobalt 31.0 mg/kg Vanadium and compounds 49.0 mg/kg Nickel (soluble salts) 69.0 mg/kg Chromium 70.0 mg/kg Copper and compounds 110.0 mg/kg Lead 210.0 mg/kg Zinc 220.0 mg/kg Barium and compounds 330.0 mg/kg

Update (Dec. 5, 2017): We have changed the source of the installation cost data after being notified by the Department of Defense that they erroneously reported their own cost figures on the DERP website. We are now displaying the costs the department says are the most accurate available, from the Pentagon’s DERP database that we received in a FOIA request.
