The site is adjacent to Camp Parks. The sewage lagoon area south of Highway 580 is currently owned by the Dublin San Ramon Services District and operated as a sewage treatment facility. A land swap between the Bay Area Regional Transit (BART), the County of Alameda, the East Bay Parks District, and the U.S. Government has been proposed and is currently pending Department of Defense (DoD) approval. Camp Parks would surrender a 35-acre tract to BART in exchange for a 445-acre tract owned by the East Bay Parks District, located northeast of the site. The 445-acre tract is currently used as a park; however, dump site/burn pit located in the southeastern portion of the site was reportedly used by the Navy hospital. Camp Parks has initiated an investigation of the site in anticipation of the land transfers. The Santa Rita County Jail was operated on the former site of the Naval disciplinary barracks until 1989. The entire site was beneficially used by the County of Alameda. Of the nine underground storage tanks (USTs) located on the site, five were removed in 1990. Two 20,000-gallon USTs were abondoned in place in 1985. The northern third of the parcel has been recently developed with the addition of the new Santa Rita County Jail, a Highway Patrol building, and a Sherriff's Department facility. The Sherriff's Department utilizes an old DoD rifle range on the northern border of the property. (Source: U.S. Army Corps of Engineers) « see less

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.

Note: The risk level of a site refers to a relative risk assessment made by the DOD to prioritize the cleanup of sites.
