Problems/Comments
Quarters Building 101 formerly utilized a 1,200-gallon UST that supplied heating oil for the building furnace. UST 28-G-1 was decommissioned in FY98, and approximately 40 cubic yards of contaminated soil were excavated and stockpiled at the RTR/DF Building. A FY99 RI detected DRO, GRO, and BTEX above ADEC cleanup standards in soil samples in the vicinity of the UST excavation. Groundwater was sampled east-northeast of Building 101, which is hydraulically downgradient of the decommissioned UST. Groundwater was found to contain benzene, GRO, and DRO in excess of ADEC cleanup standards. 2010 SI found groundwater with GRO at 7.4 mg/l, DRO 1.95 mg/l. Soil GRO 940 mg/kg, DRO 21,000 mg/kg, benzene 0.074 mg/kg and ethylbenzene 8.9 mg/kg. Smear zone area estimated at 140 x 80 feet.

| 12/10/2015 | Meeting or Teleconference Held | DEC staff attended a meeting with FAA PM Raymore to discuss the current status and path forward at the FAA Cold Bay Station sites. Planned work includes an evaluation of remediation technologies for the contamination detected in soil and groundwater. | Monte Garroutte |
| 2/4/2016 | Document, Report, or Work plan Review - other | The Alaska Department of Environmental Conservation (DEC) approved the Groundwater Sampling Report, Cold Bay Groundwater Sampling and Feasibility Study, Cold Bay, Alaska. This report summarizes the 2015 groundwater sampling activities which were conducted at the FAA Cold Bay sites. This included the investigation of the following six areas of concern (AOCs): 1. Building 101 – Former Living Quarters 2. Building 102 – Former Living Quarters 3. Building 104 – Former Living Quarters 4. Building 107 – Former Living Quarters 5. Building 207 – Former Water Treatment Plant 6. Building 208 – Former Gasoline Shed DRO exceeds the groundwater cleanup level in at least one well at each AOC. Free product is present in well MW-12H, which is in the Building 207 AOC. Recommendations for each AOC will be addressed in the upcoming feasibility study for the site. | Monte Garroutte |
| 1/14/2019 | Document, Report, or Work plan Review - other | DEC approved the In-Situ Remediation Pilot Study and Product Bail-Down Testing Final Report, Cold Bay Alaska (Dated December 2018). The report describes field activities and results from an in-situ remediation pilot study and product bail-down test at the Federal Aviation Administration (FAA) section in Cold Bay, Alaska. The purpose of the study was to evaluate in-situ chemical oxidation (ISCO) as a remedial alternative for the site. Bail-down testing was performed to determine whether development of a product recovery system would be a viable option. Recommendations from the report were, the ISCO pilot study test is not recommended for this site, and bail down testing indicated that product was not practically recoverable. Other remedial alternatives may need to be explored for future site cleanup work at the FAA sites. | Erica Blake |
