Photos in this gallery show a few examples of environmental cleanup that the Navy has carried out at Alameda Point. The featured photos are from the last four years. Although some environmental cleanup and limited groundwater testing occurred when Alameda Point was an active military base, cleanup didn't get serious until the base closed in 1997.

By 1999, the Navy had either removed, or cleaned and sealed with concrete, 13 miles of underground fuel lines. Cleanup was expected to be completed for transfer to the city by 2000. However, more testing of soil and groundwater led, instead, to Alameda Point entering the EPA's Superfund cleanup program in 2000.

Most of the cleanup work is carried out under the Superfund program, also known as CERCLA (Comprehensive Environmental Response Compensation and Liability Act). Contamination that is strictly petroleum-related is handled under the Petroleum Program. Radiological contamination inside of buildings in which radium-226 was used is handled by a special radiological affairs program. All cleanup work is paid for by the Navy. As of 2013, over $500 million has been spent or allocated.

The majority of the active cleanup operations will be completed by 2014, with a few areas taking until 2019.
