Interim Removal Action Approved |
Approximately 350 cubic yards of POL contaminated soils was excavated during the removal of Fort Greely Underground Storage Tanks (UST) numbers 440 and 441. The POL contaminated soils will be transported to FMW LLC, which is an ADEC approved soil treatment facility. Further cleanup is needed at site. |

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 |
ADEC recieved a site characterization summary report dated Feb 2005. The report presents results of further site characterization efforts at the Fort Greely Fuel Facility. Borehole data indicate the presence of contamination at a depth of 111-131 feet below ground surface. Sampling of a well approximately 200 feet downgradient from the valve pit indicates low-level ground-water contamination at the well, but levels are below ADEC cleanup levels. The report is adequate, but ADEC does not consider it a complete site characterization according to 18 AAC 75.335 because the conceptual site model, proposed cleanup levels, and/or proposed cleanup techniques are not included. |

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.

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. |
