Problems/Comments

2421 Flightline Avenue, also known as Former Building 1138/Eastern Area, is one of five CITS sites. There is a municipal drinking water well less than 1 mile upgradient of the site and Garrison Slough is less than 0.25 miles cross-gradient from the site. Approximately 25 cubic yards of soil were removed and thermally treated in 2001. 2002 soil sampling identified DRO up to 14,000 mg/kg and benzene up to 0.0434 mg/kg. Groundwater sampling that same year identified DRO up to 25.4 mg/L and RRO up to 1.38 mg/L. Sampling for PAHs and other potential contaminants of concern (based on current and former site usage) has not been done. A 2006 email from ADEC to Eielson requested consideration of possible remedial actions at this site and noted that the direction of groundwater flow needs to be identified based on site-specific, not base-wide, information.

Action Date Action Description DEC Staff
9/7/2001 Site Added to Database Petroleum contamination. Bruce Wanstall
9/7/2001 Site Ranked Using the AHRM Preliminary ranking. Municipal DW well is within one mile of the site and located hydrologicaly up-gradient from the site. Garrison Slough is less than 1/4 mile away and cross-gradient from the site. Bruce Wanstall
12/26/2001 GIS Position Updated Worked with Heather Goldman obtaining GIS latitude and longitude from 1:63,300 topographic map. Heather Goldman
8/18/2004 Site Characterization Workplan Approved work plan described work for contamination discovered during installation of the COmbat Information Training System (CITS) fiber optic cable. Monitoring wells will be installed and soil and groundwater will be tested for fuel components. Sharon Richmond
3/1/2005 Meeting or Teleconference Held ADEC met with Eielson AFB and contractor to review the Draft Site Characterization report for the CITS sites. QA/QC issues were discussed and there is a need for further data validation before the report can be approved. Contaminants of conern in the soil are DRO and remaining contamination exceeds ADEC cleanup levels. PAH sampling did not occur at Bldg. 1138. DRO exists in the ground water above cleanup levels. DRO exists in the soil above the maximum allowables and benzene was exceeded in one soil sample. Emily Youcha
4/22/2008 Exposure Tracking Model Ranking Initial ranking with ETM completed. Deborah Williams
1/21/2011 Update or Other Action This entry contains only site-specific information. An informational site has been added to the database for actions that pertain to Eielson Air Force Base in its entirety.

6/13/2014 Update or Other Action On April 23, 2014, the Alaska Department of Environmental Conservation and the United States Air Force reached agreement on the State-Eielson Air Force Base Petroleum Site Restoration Agreement (Two-party Agreement). This agreement was established to perform any necessary assessment, monitoring, remediation and cleanup determinations for petroleum contaminated sites at Eielson Air Force Base. This site was identified as a petroleum contaminated site requiring a response action and its cleanup will continue under Alaska regulations, following the procedures established in the agreement. Monte Garroutte
11/5/2014 Exposure Tracking Model Ranking A new updated ranking with ETM has been completed for source area 74664 Building 1138. Restrictions are currently in place to prevent contaminant exposures. Approval is required for any activity on site that can result in access or movement of groundwater or soil. The installation or use of drinking water wells is restricted, and all monitoring wells are secured with locks to prevent unauthorized access to groundwater. Additionally, a 200-foot buffer boundary is on the site until better delineation can be defined. Anna Iverson
