Chalkyitsik Site Characterization Project Report, submitted by Oasis, with this date. Areas potentially contaminated by fuel at the existing tank farm and various other fuel storage and transfer tanks in the village were targeted for assessment. The goal was to access the amount of fuel contamination present in site soils and groundwater, develop a preliminary evaluation of the risk posed by the contamination, and to develop recommendations regarding how to remediate the sites. Two types of sites were investigated: primary sites including the existing tank farm and secondary sites such as small fuel storage tanks and/or potential spill sites. Multiple sites were found throughout Chalkyitsik with contamination above ADEC cleanup levels. |
