Fort Barry
Fort Barry is a former United States Army installation on the West Coast of the United States, located in the Marin Headlands of Marin County, California, north of San Francisco. Opened in 1908, the fort was part of the Coast Artillery Corps and operated throughout the 20th century, before its closure and eventual transfer to the National Park Service.

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.

Final Cleanup ActionGW 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.

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.
