Problems/Comments
Excavation in 1991 of a 1,000 gallon gasoline USTand a nearby floor drain showed soil contamination from leaks and spills. Samples taken from the limits of excavation (11.5 feet bgs) were non-detect for GRO and BTEX. Groundwater was impacted by benzene. Quarterly monitoring in 1995 showed benzene levels ranging from 3 ppb to 12 ppb. In 2001 20 cubic yards of soil stockpiled from the 1991 excavation were approved for transport to OIT for thermal remediation.

| 6/6/2007 | Exposure Tracking Model Ranking | Updated Ranking Complete for Source Area: 77825 (Autogenerated Action) | |
| 6/8/2007 | Update or Other Action | Received "Monitoring Well Sampling Results, Sophie Plaza Apartments, Fairbanks, AK" from Shannon & Wilson. Assessment of current GW quality shows GRO, benzene, VOC's and PAH's below ADEC Table C Groundwater Cleanup Levels. Residual contaminants were detected (benzene at 1.55 ug/L and trichlorofluoromethane at 23.5 ug/L), but not at levels above ADEC cleanup levels. | Shannon Oelkers |
| 7/16/2007 | Site Closure Approved | The June 2007 groundwater report did not detect contamination above Table C cleanup levels. The monitor well was downgradient from the gasoline tank (and a former floor drain). The tank and impacted soil were removed in 1991. Benzene levels were as high as 19 ppb but now meet cleanup levels. Closure decision issued on July 13, 2007 for tank site and floor drain. | Jim Frechione |
