Problems/Comments

Site in and near village was used by the Army, Air Force and Navy from 1948 and abandoned in 1950s. The majority of contaminants were petroleum in soils. There were also low level PCBsand dioxins. Buried debris which occasionally surfaces from erosion or new construction has been a problem in the community. Unexploded ordnance reportedly buried near or in Troutman Lake. The investigation did not locate any ammo caches. See the Gambell Facility Wide site for a complete action list Site 5 is the former tramway site located on the west face of Sevuokuk Mountain adjacent to the current drinking water supply. Geophysical investigations were done in 1994, 1996 and 1998. Two intert debris anomalies were excavated. No soil contamination was evident. A subsurface soil investigation did detected POL contamination above cleanup levels in one boring. Groundwater wells were installed and sampled in the area in 1994 adn 1998. Diesel Range Organics slightly over screening levles were noted in a monitoring well (MW31) crossgradient from the aquifer. Follow up investigation in 1998 showed no impacts to the water supply well. Another sampling event of area monitoring wells is scheduled for 2005 and 2006. The village water supply is tested every year. The Gambell site extends west from North Beach to West Beach, south to Nayvaghaq Lake, and east to include portions of Sevuokuk Mountain. The site encompasses the Village of Gambell. Last staff assigned were Noland, Ortelee, Kalu, Stephens, Rutkowski and Brownlee. (rpltr6)

6/27/2005 Record of Decision A decision document was signed for Formerly Used Defense Sites at Gambell. Thirty four of thirty eight sites have been characterized, cleaned up and closed; soil cleanup methods and levels were formalized for two sites; debris cleanup will be conducted at a third site; one site was withheld from the decision document due to data gaps the Corps determined it needed to address before signing a decision on it. Jeff Brownlee
1/25/2007 Meeting or Teleconference Held Contaminated Sites staff participated in a Restoration Advisory Board (RAB) meeting for the Formerly Used Defense Sites (FUDS) on Saint Lawrence Island. Participants at the meeting included Alaska Community Action on Toxins (ACAT), the RAB Technical Assistance Program representative, the COE Alaska District, the native corporation attorney, RAB members and DEC. Agenda items included discussion of the remedial actions that took place in Gambell during the summer season included a summary of the Native American Lands Environmental Mitigation Program (NALEMP) work. The Gambell NALEMP project is the largest in the nation with 290,000 pounds of buried debris removed in 2006. There was discussion on the groundwater sampling event at Site 5 which is several monitoring wells surrounding the village water supply well. There were detected levels of DRO and metals (lead, nickel, barium) in a couple wells, but well below the cleanup levels. We also discussed the Feasibility Study for Northeast Cape and the upcoming final of that document Jeff Brownlee
3/22/2007 Site Characterization Report Approved CS staff reviewed a groundwater monitoring report for the Site 5 Formerly Used Defense Site in Gambell on Saint Lawrence Island. Site 5 is a groundwater monitoring array that surrounds the main intake well for the village drinking water source. All results were well below Table C cleanup levels Jeff Brownlee
