Problems/Comments

Dioxin and metals detected in soil during base realignment and closure investigation. Refuse burn pit is used to burn combustible garbage prior to disposal in the landfill. Paint, oily sludge from oil-water separators, contaminated soils and sorbents, and aerosol cans have reportedly been burned here. An incinerator will replace the burn pit upon completion, probably in 2005. This site is investigated under the BRAC process for Fort Greely. The site is known Parcel 89. Site was transferred to the Space Defense Missile Defense Command (SMDC) in October 2002. SMDC has assumed cleanup responsibility. 2009 Corretive Action activities included excavation and off-site disposal of 350 tons of soil. An asphalt cap with a gravel apron was constructed over the impacted area.

12/26/2000 Site Added to Database Pesticides and metals. Bruce Wanstall
12/26/2000 Site Ranked Using the AHRM Prelimiary ranking. Bruce Wanstall
1/3/2001 Update or Other Action Site is investigated under BRAC. It is expected that the Army will propose Method III ACLs. A proposed plan is expected early 2001. Greg Light
11/7/2002 Update or Other Action Proposed Plan from SMDC pending. Greg Light
10/1/2004 Institutional Control Record Established In the October 2004 Draft Decision Document Fact Sheets, administrative controls (ACs)were established in order to minimize risk to human health and the environment. The site is included in the post’s Geographic Information System (GIS), a tool used in the Dig Permit process for notifying contractors, workers, and base personnel of the potential for contamination to exist at this site. The Dig Permit process is used to prevent installation of water production well(s) through the contaminated area, and prevent removal of contaminated material from the site to off-base locations or to environmentally sensitive areas. If future land disturbance activities at the site encounter contamination, the contaminated material encountered will be properly remediated or disposed of in accordance with applicable regulations. The site will be included in 5-year reviews to periodically verify compliance with the ACs. If Fort Greely is transferred to another agency or party, formal ICs will be implemented at the site due to cumulative risk under the residentiall exposure scenario exceed ADEC threshold. The ICs will provide notification of restrictions for industrial/commercial exposure and will take the form of deed restrictions or similarly stringent site requirements under official post land documentation. The purpose of the IC will be to maintain industrial/commercial usage of the site and prevent future developement of the site for residential purposes. The site is currently fenced with a secured gate allowing access only by authorized personnel. Emily Youcha
12/14/2004 Update or Other Action Lead and dioxin/furan remain as contaminants of potential concern. Background sampling and evaluation of metals was conducted in 1999 and the elevated detections of arsenic, cadmium, and chromium from the 1997 sampling were resolved as background. Emily Youcha
12/14/2004 Update or Other Action Staff received "memorandum for record" factsheet from SMDC and administrative controls have been established for the site. Further investigation was recommended by ADEC into PCBs and pesticides for this site. Emily Youcha
12/20/2004 Update or Other Action ADEC reviewed a report titled "Comprehensive evaluation of groundwater monitoring program Fort Greely, Alaska". The report discussed the existing monitoring network at Fort Greely and the parameters evaluated in ground-water sampling events. ADEC recommended additional investigation into infiltration and vertical hydraulic gradients. ADEC also recommended additional monitoring wells in the Old Post area and more ground-water monitoring at certain specific sites. Emily Youcha
4/11/2005 Site Characterization Workplan Approved Previous work from 1997-1999 detected lead, dioxins and furans at depths less than 7 ft below ground surface. In 2005, the investigation will focus on an area where soil data was previously collected in a surface depression. Samples will be analyzed for pesticides, PCBs, dioxins/furans, and lead. Two borings will be drilled in a depression area on the east side and will be advanced to 10 ft. One boring will be drilled on the east side. Samples will be collected at 5 and 7 ft below ground surface. Emily Youcha
5/25/2005 Meeting or Teleconference Held Staff conducted a site visit of Fort Greely.

12/28/2007 Update or Other Action ADEC provided comments to the Draft 2006 RI for Fort Greely. According to the 2006 RI, 26 shallow (6' bgs) borings were installed to delineate the lateral and vertical extent of soil contamination. Twenty-five primary samples from varying depths at 21 locations were analyzed for dioxins/furans and lead. Three borings exceeded risk-based soil cleanup levels for dioxins/furans (as 2,3,7,8 TCDD) for residential land use in Alaska. Five borings contained total lead concentrations in excess of ADEC Method Two cleanup levels for residential use. The consultant recommends excavating the area where the lead levels exceed industrial cleanup levels. The area is estimated to a depth of six feet (approx. 30 CY). The consultant recommends that the remaining area be capped with asphalt and left in place as remediation. (An area of approximately 70 feet by 75 feet will have three feet of fill with a soild cap of asphalt. Deborah Williams
