Problems/Comments

Building 612 (BRAC 135) is located at the northwest corner of East Fifth Avenue and Arctic Avenue, within the administrative and industrial area of Fort Greely (FGA). A dry well was installed in 1953 at a location southeast of Building 612. Reportedly the dry well was suspected to have been once connected to a floor drain inside the former battery room of the building. This dry well is no longer in use. Investigative sampling efforts to determine whether the site was impacted by contamination occurred in 1997 and 2007 by various contractors. No contaminants of potential concern (COPCs) were detected in the soils above 18 AAC 75.341 Table B1 and Table B2 cleanup levels. Depth to groundwater at this site is 185 feet below ground surface. In 2008, an additional soil sample was collected and analyzed for metals. Arsenic was detected above the DEC cleanup level, however the result was within background concentrations for Fort Greely. The dry well was decommissioned and closed in place 2009. The Army number for this site is HQAES#: 02341.1030. BRAC is defined as Base Realignment and Closure.

11/17/2000 Update or Other Action Investigated under the BRAC process, Army has proposed NFA for this site. Greg Light
12/14/2004 Update or Other Action A geophysical survey was conducted in 1997 to identify the location of the drywell. One soil boring was drilled at the drywell location and all analyte detections were below ADEC Method Two cleanup levels. However, investigation samples were not analyzed for GRO, DRO, RRO, PAH, pesticides, or PCBs. SMDC has established administrative controls on this site and the drywell will be closed out in accordance with EPAs UIC program. No Further Remedial Action Planned is proposed for this site by SMDC. Decision document is pending. 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

5/23/2007 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. Zachary Richter
7/2/2007 Update or Other Action The Alaska Department of Environmental Conservation (ADEC) has completed its assessment of the environmental laboratory data and quality assurance requirements as set forth in ADEC Technical Memorandum 06-002 for the Groundwater Monitoring 2006 Analytical Data Report Fort Greely, Alaska, February 2007. The report adequately addresses the requirements set forth by ADEC for both laboratory data packages and Quality Assurance (QA) Summaries, therefore the report is approved. Zachary Richter

11/5/2008 Meeting or Teleconference Held ADEC staff participated in the Restoration Advisory Board meeting for Fort Greely in Delta Junction. During the meeting, Glen Shonkwiler with the United States Army Space and Missile Defense Command presented the fieldwork that was completed during the 2008 field season at Fort Greely. The 2008 fieldwork included remediating the soil in the biocell at the South Tank Farm (STF); conducting further delineation of the subsurface soils at the STF; installing four groundwater monitoring wells in the Old Post area and downgradient of the STF; completing the investigation at the MOGAS fuel line in the Old Post area; conducting additional survey of the Jarvis Creek Munitions Burial site; and conducting additional investigation of the Building 675 vault. He also presented the work that was planned to be completed during 2009. Deborah Williams
10/21/2009 Document, Report, or Work plan Review - other ADEC staff reviewed the document titled Draft 2008 Groundwater Monitoring and Data Analysis Report, Fort Greely, Alaska, dated March 2009. The Fort Greely groundwater monitoring program consists of monitoring wells that were installed during investigation activities on FGA from 1997 to the present. DEC approved a comprehensive groundwater monitoring approach in the 2005 Work Plan. Yearly modifications to the 2005 workplan are incorporated as needed to address environmental program objectives. Monitoring well locations and sampling frequency have been chosen to provide site specific monitoring where necessary, and comprehensive coverage for the old post and main cantonment areas of Fort Greely. Currently, a total of 30 wells are included in the groundwater monitoring program: 11 of these are sampled during the spring and fall on even numbered years, two drinking water wells are sampled quarterly, and 17 monitoring wells are sampled semi–annually. This report summarizes the 2008 groundwater monitoring efforts. A letter detailing staff comments has been provided to the Army. Tana Robert

Analytical results from four monitoring wells at the BRAC 94 site were above cleanup levels for diesel range organics, gasoline range organics, and/or benzene. Results from one monitoring well at the South Tank Farm site were above the cleanup level for ethylene dibromide. All other results were either non-detect or below the cleanup level, including all supply well results. Melody Debenham
9/27/2019 Update or Other Action DEC evaluated this site for closure. Because this site has no contaminants of concern above DEC cleanup levels, the site status has been changed from 'Active' to 'Non-Qualifying.' Erica Blake
