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. |

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. |
