Problems/Comments

The former Tar and Asphalt Disposal Area (TAADA) consists of 10 to 20 acres on the west side of the Allen Army Airfield (AAAF) and was historically used for aircraft parking and as a disposal area for asphalt drums and tar. In 1992, a preliminary visual assessment identified pools of asphalt tar, timber cribs filled with tar, and debris including drums, cables, pipes, and chunks of graveled asphalt at the site. Investigations at the site have found four asphalt disposal areas and one drum/asphalt burial area. Environmental investigations from 1994 to 2007 found no analytical exceedances of any contaminants of concern (COC). The monitoring well (TAADA) was originally used as an industrial supply well, but is now currently used for groundwater monitoring. Groundwater monitoring occurs twice a year, annually, and is analyzed for gasoline range organics (GRO), diesel range organics (DRO), benzene, toluene, ethylbenzene, xylenes (BTEX). The TAADA well has not had any exceedances since 2010. Since this site still has buried material present and is not suitable for unrestricted use, groundwater monitoring of the TAADA well is expected to continue. The corresponding U.S. Army HQAES site number is: 02341.1027. This site does not have a Base Realignment and Closure (BRAC) number.

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.
