| Abstract |
This Explanation of Significant Differences (ESD) is for a change to the remedy selected in the Record of Decision for Parcel B, Hunters Point Shipyard dated October 7, 1997 (PB98-964501). In the Parcel B ROD< the Navy's selected remedy for contaminated soils located on Parcel B was excavation to the groundwater table followed by offsite disposal. The depth to groundwater below Parcel B was believed to typically occur at 10 feet below ground surface (bgs). However, in early 998, fieldwork on the Site indicated that the depth to groundwater beneath Parcel B could be as shallow as 2.3 feet bgs. This ESD revises the selected remedy of the Parcel B ROD to require cleanup of contaminated soils to a cleanup level of 10 to the -6th power cancer risk (residential) or to a maximum depth of 10 feet bgs instead of the groundwater table to ensure that the Parcel B remedy is protective of human health and the environment. |
