Document Title: USACE Decision Document, Gambell Formerly Used Defense Site, St. Lawrence Island, Alaska
Agency/Organization: USACE

Document Summary:
This USACE Decision Document finds two discrete areas of contaminated soil that are present at Sites 7 and 12 of the Gambell Formerly Used Defnese Site. The selected remedy at Site 7 is excavation and off-Island disposal of an estimated 4 tons of soil containing greater than the cleanup level of 11 mg/kg arsenic. The selected remedy at Site 12 is excavation of off-Island disposal of an estimated 4 tons of soil containing greater than the cleanup levels of 400 mg/kg lead and 26 mg/kg chromium. According to the assessment, "the debris poses a clear danger to local residents due to the shapr and jagged edges which protrude above the ground surface and large piles which create a navigation hazard during the winter when partially covered by snow."
