The San Francisco Bay Naval Shipyard has a rich history that spans over a century. Established in 1891, it was initially used as a repair yard for the US Navy's Pacific Fleet.
The shipyard's strategic location on the San Francisco Bay made it an ideal spot for naval operations. Its proximity to the Pacific Ocean allowed for easy access to the open sea and facilitated the movement of ships in and out of the yard.
The shipyard's early years were marked by rapid growth and expansion, with the addition of new facilities and equipment to support the increasing demand for naval repairs and maintenance. By the early 20th century, the shipyard had become a major hub for naval activity in the Pacific.
One of the shipyard's most notable features is its dry dock, which was completed in 1905 and was one of the largest in the world at the time.

Background Information
The Hunters Point Naval Shipyard was a significant industrial site in southeastern San Francisco that operated from 1939 to 1974. It housed the Naval Radiological Defense Laboratory from 1946 to 1969.
The Navy's activities at the shipyard contaminated the soil and groundwater, as well as surface water and sediment in the San Francisco Bay. The contaminants included petroleum fuels, pesticides, heavy metals, polychlorinated biphenyls (PCBs), volatile organic compounds (VOCs), and radionuclides.
The site also contained naturally occurring asbestos and metals in the native soil. The Navy is responsible for investigating and cleaning up the site, with the US EPA and California state regulatory partners overseeing and enforcing their activities.
The cleanup site does not include Parcel A, which was used for residential and administrative purposes. The Shipyard was added to the National Priorities List (NPL) in 1989, making it eligible for long-term funding under the federal Superfund program.
