Problems/Comments

This site is generally known as the Firefighter Training Area, and is investigated under the Base Realignment and Closure (BRAC) program as Parcel 133. BRAC Site 133 was used as a firefighter training area from 1975 to 1985. This site contains a grass field, a concrete fill area, and a forested area. The site previously contained a drum storage area and an unlined 6-foot deep pit approximately 20 by 30 feet in size. The burn pit was used to burn waste fuels, oils, solvents, pesticides, paints, and other liquids generated by aircraft and motor maintenance activities. The estimated quantities of waste oil/hydraulic oil and waste fuels burned at the site amount to 19,180 and 2,610 gallons, respectively. Estimated quantities of paints, solvents, and miscellaneous liquids burned amount to 158,400 gallons. Prior to burning, the liquids were stored on site in an unlined and unbermed 55-gallon drum storage area. During initial soil investigations conducted in 1991, contaminants of concern (COCs) identified in the soil were; diesel range organics (DRO), tetrachloroethene (TCE), methylene chloride and antimony. In 1994 and 1997, an in-situ landfarm was constructed and operated to treat soils from the surface to 5 feet below ground surface (bgs). Trenches were excavated, irrigated, turned, and backfilled for two years. In 2010 a soil investigation was conducted to characterize the extent of contamination around the landfarm perimeter berm, and to determine the vertical extent inside the landfarm. DRO and dichlorodiphenyldichloroethane (DDD) were detected in the top two feet of soil above cleanup levels. Soil contamination remains at this site. From 2003 to 2011, groundwater monitoring wells were installed and sampled. TCE was detected above groundwater cleanup levels in Monitoring Well (MW)-2 from 2003-2007. In 2016 Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic acid (PFOA) were added to the groundwater monitoring program. PFOS and PFOA have been detected below the project action level of 0.4 µg/L but above the EPA Health Advisory level of 0.07 µg/L. Groundwater monitoring is expected to continue at this site. The U.S. Army HQAES site number is: 02341.1006. Associated sites; Fort Greely Former Fire Training Area BRAC 85N (Hazard ID: 4245) and Fort Greely Former Fire Training Area BRAC 85S (Hazard ID: 1429).

12/2/2002	Update or Other Action	Please note that this site was turned over from BRAC to SMDC. A fact sheet was developed summarizing the activities at this site. The upper 5 ft of impacted soil in the former fire training pit area was landfarmed by trenching, irrigating, turning, and backfilling the contaminated soil. Soil samples were collected during the process to monitor remediation progress. Additional sampling was conducted in 1998 under BRAC. DDT exceeded migration to groundwater and the ingestion cleanup levels. Cumulative risk standards were exceeded.	Emily Youcha
10/1/2004	Update or Other Action	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.	Emily Youcha
12/14/2004	Update or Other Action	A risk assessment was submitted to ADEC in 2002 for sites 85N, 85S, 133, and 112, however it was not approved by ADEC. Soil was placed over the contaminated areas in summer 2002 as a site control measure.	Emily Youcha
12/14/2004	Update or Other Action	ADEC received a "memorandum for record" factsheet on site 85N, 85S, and 133. SMDC proposes administrative controls are established at the site, 5-yr reviews, a soil cap, and Further investigation may be needed into 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
5/24/2005	Site Characterization Workplan Approved	A workplan for Summer 2004 and Summer 2005 was approved. The summer 2004 work consisted of soil gas monitoring at site BRAC 85, BRAC 133, and the rest of the Old Post area. This site was suspected to be the source of recent detections of TCE in the groundwater, however, other areas of the Old Post are also suspect. The summer 2005 workplan involves further soil gas surveys, drilling deep boreholes to characterize the vertical extent of contamination, and decommisioning the bioventing system at BRAC 85.	Emily Youcha
5/25/2005	Meeting or Teleconference Held	Staff conducted a site visit of Fort Greely. Summer fieldwork is underway and includes soil gas surveys, drilling and sampling several deep boreholes, and installation of at least two new monitoring wells.

9/30/2005	Update or Other Action	Staff particpiated in a Restoration Advisory Board Meeting for Fort Greely on September 28.	Emily Youcha
11/29/2005	Update or Other Action	The Army requested that ADEC review the 2002 Risk Assessment and Soil Evaluation. The ADEC risk assessor reviewed the risk assessment for site 85N (revision 1, dated Dec 6, 2002) and found that the exposure assumptions were not protective and so further work on the risk assessment is required for 85N. Method Three calculations were made for sites 85S, 112, and 133 for an industrial scenario. Some contamination still exceeded the migration to ground water Method Three cleanup levels. At site 133, some contamination exceeded the Method Three migration to ground water cleanup level. ADEC is requesting the Army review the conceptual site model (CSM) for each fire training site to ensure the CSM hasn't changed during the conversion from BRAC to SMDC. ADEC and SMDC will review leachibility modeling and current field results to evaluate the migration to ground water pathway.	Emily Youcha
12/7/2005	Site Ranked Using the AHRM	Changed the ranking for ground water exposure index from 0 to 1.0 because of recently detected ground-water contamination found at downgradient monitoring wells, thought to be associated with this site. Ranking remains medium priority.	Emily Youcha

Update or Other Action

Please note that this site was turned over from BRAC to SMDC. A fact sheet was developed summarizing the activities at this site. The upper 5 ft of impacted soil in the former fire training pit area was landfarmed by trenching, irrigating, turning, and backfilling the contaminated soil. Soil samples were collected during the process to monitor remediation progress. Additional sampling was conducted in 1998 under BRAC. DDT exceeded migration to groundwater and the ingestion cleanup levels. Cumulative risk standards were exceeded.

Emily Youcha

10/1/2004

Update or Other Action

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.

12/14/2004

Update or Other Action

A risk assessment was submitted to ADEC in 2002 for sites 85N, 85S, 133, and 112, however it was not approved by ADEC. Soil was placed over the contaminated areas in summer 2002 as a site control measure.

Emily Youcha

12/14/2004

Update or Other Action

ADEC received a "memorandum for record" factsheet on site 85N, 85S, and 133. SMDC proposes administrative controls are established at the site, 5-yr reviews, a soil cap, and Further investigation may be needed into this site.

Emily Youcha

Site Characterization Workplan Approved

A workplan for Summer 2004 and Summer 2005 was approved. The summer 2004 work consisted of soil gas monitoring at site BRAC 85, BRAC 133, and the rest of the Old Post area. This site was suspected to be the source of recent detections of TCE in the groundwater, however, other areas of the Old Post are also suspect. The summer 2005 workplan involves further soil gas surveys, drilling deep boreholes to characterize the vertical extent of contamination, and decommisioning the bioventing system at BRAC 85.

11/29/2005

Update or Other Action

The Army requested that ADEC review the 2002 Risk Assessment and Soil Evaluation. The ADEC risk assessor reviewed the risk assessment for site 85N (revision 1, dated Dec 6, 2002) and found that the exposure assumptions were not protective and so further work on the risk assessment is required for 85N. Method Three calculations were made for sites 85S, 112, and 133 for an industrial scenario. Some contamination still exceeded the migration to ground water Method Three cleanup levels. At site 133, some contamination exceeded the Method Three migration to ground water cleanup level. ADEC is requesting the Army review the conceptual site model (CSM) for each fire training site to ensure the CSM hasn't changed during the conversion from BRAC to SMDC. ADEC and SMDC will review leachibility modeling and current field results to evaluate the migration to ground water pathway.

Update or Other Action

The Alaska Department of Environmental Conservation (ADEC) received the Groundwater Monitoring and Data Analysis Work Plan Fort Greely, Alaska on April 27, 2007. This work plan abides by the 2005 Final Work Plan with modifications to the wells and analytical parameters to be monitored particularly the addition of polycyclic aromatic hydrocarbon analysis at monitoring wells MW-12, MW-13, and MW-14. Additionally, the pump type used in sampling the monitoring wells will be changed by replacing the Grundfos Ready Flow pump with a QED Sample Pro 1.75 inch bladder pump and QED MP10 controller, or equivalent. All other sampling methodology will remain the same as the 2005 Final Plan. The final modification to the 2007 Work Plan is the addition of Volatile Organic Analysis/1,2-dibromoethane monitoring at drinking water wells ECP2 and ISFAC at the missile field. An updated list of wells to be monitored, and the parameter for analysis from each well, for upcoming sampling events has been provided to replace Table 5 of the 2005 Final Work Plan. ADEC has completed its review of this document and has found that the Groundwater Monitoring and Data Analysis Work Plan Fort Greely, Alaska for 2007 adequately meets the requirements set forth in 18AAC75.355, and with the addition of the previously agreed upon amendment, this work plan is approved.
