Problems/Comments
Quarters Building 107 formerly utilized a 1,000-gallon UST that supplied fuel oil to the residents. UST 28-G-9 was decommissioned in FY96, and approximately 100 cubic yards of DRO-contaminated soil were excavated. The high DRO levels at the site and the porous nature of the gravel beneath the tank merited additional investigation. A FY99 RI confirmed that soil and groundwater from the UST excavation site contained high DRO levels that exceeded ADEC cleanup standards. 2010 SI found DRO 22000 mg/kg, 17' bgs. Groundwater at source area contained DRO at 7.76 mg/l.

| 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 |
