A remedy was chosen from many alternatives as the best means of addressing contaminated soil and groundwater at OU-B. The major components of the preferred remedy for OU-B are: high-vacuum extraction (HVE) to remove contaminated vapors and groundwater from the 'hot spot.' The 'hot spot' is defined as the subsurface area containign greater than 1.0 milligrams per liter of 1,1,2,2-tetrachloroethane in groundwater and/or free-phase sovlents; an air strippin system to treat extracted grondwater to meed State of Alaska and federal maximum contaminant levels (MCLs) before being reinjected into the deep aquifer; institutional controls that will include restrictions on groundwater well installations, site access restrictions, and maintenance of fencing until state and federal MCLs for drinking water are met; natural attenuation of groundwater contamination in areas outside the 'hot spot'; and long-term monitoring to assess whether groundwater contamination is approaching Eagle River and to ensure that contamination levels in the groundwater are decreasing through natural attenuation.
