Problems/Comments

The Old Power Generation Building, or Building 323, is also known as Base Realignment and Closure (BRAC) 116. The 30 foot by 75 foot concrete foundation of the former Building 323 was discovered during a site investigation in 1996. The building is believed to have been a former steam generation facility and had rectangular pits/vaults along two sides of the foundation that contained apparent tank cradles. Soil staining and petroleum contaminated soils were identified during a 1998 investigation. Additional investigation and removal actions occurred in 1999, 2000, 2010, and 2011. Confirmation sample results from the removal actions show diesel range organics (DRO) contamination remaining in the subsurface soils (top 15 feet) above the ADEC migration to groundwater cleanup levels. Confirmation sidewall samples from the 2011 southeast and northwest excavation have DRO concentrations above the ADEC migration to groundwater cleanup level at depths 8 to 15 feet below ground surface. Additional site characterization work is needed to delineate the remaining contamination before this site can be closed. The corresponding Army HQAES site number is: 02341.1052.

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.
