Site Characterization Report Approved |
Approved the 2011 Site Characterization Report for the NPS Gulkana Airport site. In 1998 three underground storage tanks (USTs), one containing Jet B fuel and two containing Avgas, and associated piping were removed, however, contaminated soil was left in place. Additional site characterization activities in 2011 show that contaminated soil and suprapermafrost groundwater remain at this site, but does not appear to be migrating and remains limited to the area surrounding the original release. Clay and frozen soils restrict migration, and previous work at this site suggests that the suprapermafrost groundwater is discontinuous. The area is now covered with an asphalt tarmac. |
