Institutional Control Record Established |
In the October 2004 Draft Decision Document Fact Sheets, administrative controls (ACs)were estblished 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. |

Update or Other Action |
200 cubic yards of contaminated soil was excavated during the tank removal and the soil was placed back into the excavation. Excavation samples were analyzed for DRO and results ranged from 2,544 mg/kg and 3,669 mg/kg. A release investigation in 1996 showed DRO levels up to 6,230 mg/kg, with highest concentrations 10-32 feet below ground surface. |

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. |

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.

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. |

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. |

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. |

Document, Report, or Work plan Review - other |
Approved the final soil stockpile characterization report documenting sampling of petroleum impacted soils contained in long-term stockpiles and supersacks staged near the landfarm area. The stockpiled soil was generated during remedial actions conducted from 2010 to 2012 at multiple sites at Fort Greely, including BRAC 98. Based on the information presented in the report, and in consultation with the solid waste program, the stockpiled soil is suitable for use as daily cover at the Fort Greely landfill. |

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. |

Document, Report, or Work plan Review - other |
DEC reviewed the Draft Environmental Summary Report (ESR) for FGLY-043 Bldg 159, which details the history of site activities and the current contaminant levels known at the site to support a recommendation for closure with institutional controls. The site has incomplete vertical delineation of exceedances of the migration to groundwater cleanup levels described in 18 AAC 75.341, Tables B1 and B2 in soil, and potential impacts to groundwater, shown by exceedances of groundwater cleanup levels described in 18 AAC 75.345, Table C in downgradient monitoring well MW-15. It is currently unknown if groundwater contamination is due to the contamination associated with Building 159 or a release from further upgradient. As such, DEC does not agree with the recommendation for closure with institutional controls, and recommends instead that further delineation of soil contamination be conducted to verify the release does not impact groundwater at the site. |

Cleanup Complete Determination Issued |
Based on the information provided to date, it has been determined that the contaminant concentrations remaining on site do not pose an unacceptable risk to human health or the environment and no further remedial action will be required unless information becomes available that indicates residual contaminants may pose an unacceptable risk. No exceedances of the soil human health cleanup levels described in 18 AAC 75.341, Tables B1 and B2 remain at the site. Monitoring wells were never installed for sampling at the Building 159 site specifically, however a nearby monitoring well (MW-15) was sampled and showed an exceedance of the groundwater cleanup level described in 18 AAC 75.345, Table C for one contaminant, naphthalene, in 2021. Due to the complete vertical delineation at the site, and the known naphthalene plume from an upgradient site (Fort Greely Building 163, BRAC 94), the Army has demonstrated the contamination is not due to the release at this site. |
