Parcel G Design Basis Report Fact Sheet

Fact Sheet: Review of Parcel G Design Basis Report, Hunters Point Naval Shipyard

March 17, 2010

Prepared for a Community Meeting of the India Basin Neighborhood Association

The Navy has circulated a report that provides the design for cleanup of contaminated soil at Parcel G, a 40 acre tract that was part of an area used for shipping, ship repair, office and commercial activities. The February 10, 2010 report, entitled “Design Basis Report, Parcel G” has been prepared to implement the Record of Decision issued prepared by the Navy on February 18, 2009.

The cleanup will involve excavation of two truckloads of soil that is contaminated with lead and benzo(a)pyrene. Lead is a probable carcinogen and affects blood and the nervous system and impairs reproduction and development. Benzo(a)pyrene is a probable carcinogen. The cleanup will also involve the removal of 20 truckloads of material from soil stockpiles. The origin of the soil stockpiles is unknown and the stockpiles have not been sampled for contamination.

After excavation, Parcel G will be paved with asphalt to prevent exposure to underlying soil. The soil excavation and asphalt pavement will achieve goals for protecting the health of the public and will reduce the risks of getting cancer to a level that is less than one in a million for a person with lifetime exposure to contaminants at the site. Vapors in soil beneath Parcel G will also be tested to ensure that any occupants of buildings will not be exposed to contaminants. Groundwater underlying Parcel G is not addressed by the Design Basis Report. Groundwater was cleaned up in 2008.

Comments are due to the Navy on March 29, 2010.
