Problems/Comments

This site is generally known as Firefighter Training Area South, and is investigated under the Base Realignment and Closure (BRAC) program known as Parcel 85 South (85S). The site consisted of a depression with a rectangular pit in the center of the training area, and a drum storage area on the western edge of the pit. This site is located southeast of the southeast corner of the Allen Army Airfeld (AAAF). Several environmental investigations have occurred over the years at this site. During an initial soil investigation in 1991, benzene, diesel range organics (DRO), bunker C fuel oil, dichlorodiphenyldichloroethane (DDD), dichlorodiphenyltrichloroethane (DDT) and dichlorodiphenyltrichloroethane (DDE) were identified. From 1995 to 1997, in situ bioremediation (land farming) was used to treat surface soil, and bioventing was used to treat subsurface soil. This remediation effort went on for two years. Additional investigations to delineate the contaminated soil after the remediation efforts occurred in 1998, 2005, 2007 and 2008. In 2007, multiple soil borings were drilled to 60 feet below ground surface (bgs), and only gasoline range organics (GRO) was identified in the soil at varied concentrations. 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.

3/26/1997	Update or Other Action	Site updated by Shannon and Wilson, based on the Army Defense Site Environmental Restoration Tracking System Worksheet dated 11/8/96. The worksheet indicates soil contamination by lead at 120 ppm, DDT at 0.23 ppm, and 2,3,7,8-TCDD at 4 ppm (Fort Wainwright checking to see if this number is accurate), and states that soil could leach into groundwater.	S&W
1/3/2001	Update or Other Action	Site is under investigation under the BRAC process for Fort Greely. A proposed plan is expected from the Army early in 2001.	Greg Light
3/2/2001	Update or Other Action	Changed the DoD Rank to Medium from High per “Army Defense Site Environmental Restoration Tracking System Worksheet dated 11/8/96” as listed in the Comments field for this site.	Former Staff
11/7/2002	Update or Other Action	Site is now owned by SMDC. Methd three evaluation completed at site 133, and risk assessment at 85. Proposed Plan pending.	Greg Light
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. Four biovent wells with integral blowers were installed and operated. Respirometry was conducted during operations. Soil samples were collected during the process to monitor remediation progress. The biovent system was turned off in 1997 due to diminishing returns. Additional sampling was conducted in 1998 under BRAC. Benzo(a)Pyrene exceeded migration to groundwater and the ingestion cleanup levels. Cumulative risk standards were exceeded.	Emily Youcha
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. Groundwater monitoring will be conducted at a reduced scope of sampling that will be determined and agreed to between ADEC, EPA, and SMDC. 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.	Emily Youcha
12/14/2004	Update or Other Action	A risk assessment for 85N was submitted to ADEC in 2002. A method 3 ACL was calculated for sites 85S, 133, and 112, however it was not approved by ADEC.	Emily Youcha
12/14/2004	Update or Other Action	ADEC received a "memorandum for record" factsheet on site 85N, 85S, and 133. SMDC proposes bioventing system be decommissioned due to diminishing returns, administrative controls are established at the site, 5-yr reviews, a soil cap will be placed on the site, 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
5/24/2005	Update or Other Action	Results of the 2004 site characterization soil gas results indicate low-level PCE detections and no TCE detections. TPH was detected at BRAC parcel 85S. Further investigation into the elevated soil gas results will occur with deeper boreholes at 85S this summer. The old bioventing wells will be decommissioned.	Emily Youcha

Greg Light

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. Four biovent wells with integral blowers were installed and operated. Respirometry was conducted during operations. Soil samples were collected during the process to monitor remediation progress. The biovent system was turned off in 1997 due to diminishing returns. Additional sampling was conducted in 1998 under BRAC. Benzo(a)Pyrene exceeded migration to groundwater and the ingestion cleanup levels. Cumulative risk standards were exceeded.

Emily Youcha

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. Groundwater monitoring will be conducted at a reduced scope of sampling that will be determined and agreed to between ADEC, EPA, and SMDC. 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.

SMDC proposes bioventing system be decommissioned due to diminishing returns, administrative controls are established at the site, 5-yr reviews, a soil cap will be placed on the site, 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

5/24/2005

Update or Other Action

Results of the 2004 site characterization soil gas results indicate low-level PCE detections and no TCE detections. TPH was detected at BRAC parcel 85S. Further investigation into the elevated soil gas results will occur with deeper boreholes at 85S this summer. The old bioventing wells will be decommissioned.
