Sign #2: Partial View of Current and Former Toxic Sites on Parcels E & F

Naval operations at the Hunters Point Shipyard have seriously polluted the property and surrounding bay. The Shipyard is now on the Superfund list and has been divided into six parcels to make the cleanup easier to manage (see smaller map to the left). You are looking out on a portion of Parcels E and F. Parcel E is roughly 150 acres in size and has numerous toxic and radiologically contaminated areas. The industrial landfill shown in the picture caught fire in 2000 and a large clay and soil covering was placed on top to smother it (# 6 on the picture). This site is now being treated to reduce levels of methane gas.

Parcel F is the underwater portion of the Shipyard. There is incomplete information about the degree of contamination, however serious PCB contamination in South Basin and Yosemite Slough has been found.

The current and former toxic and radiological cleanup sites you can see from this vantage point are numbered in the graphic below and noted below.

1. PCB-Contaminated Sediments
2. 18-acre Radiological Landfill
3. Building 815 – Filesafe - The Former HPS Naval Radiological Defense Laboratory (NRDL) (Radiological clearance by NRC in 1978)
4. PCB-Contaminated Sediments
5. Sheet Pile Wall: Prevent Leaching of Toxins into South Basin
6. 46-acre Industrial Landfill – Site of 2000 Fire
7. Extraction Trench for Methane Gas Treatment
8. Former NRDL Biological Lab Kennels
9. PCB-Contaminated Sediments
10. Building 821 Former X-ray Shield
11. Building 820 Former Cyclotron Facility

This sign was installed January 2004 at the intersections of Earl and LaSalle Streets on Hunters Point Hill ovelooking Yosemite Slough in San Francisco. Sign has been altered for online presentation. The Interpretive Tour Of Hunters Point Shipyard is part of The Community Window on the Shipyard Cleanup, a project of Arc Ecology funded by a grant from San Francisco Department of the Environment.
