Report of results of the vapor vacuum extraction test at the Radioactive Waste Management Complex (RWMC) on the Idaho National Engineering Laboratory (INEL) in the state of Idaho

A test-scale vapor vacuum extraction (VVE) system was installed and operated at the Radioactive Waste Management Complex (RWMC) on the Idaho National Engineering Laboratory (INEL), which is west of Idaho Falls, Idaho and is managed by the US Department of Energy Idaho Field Office. The system was constructed for the purpose of demonstrating the feasibility of VVE or vapor venting technology to abate a volatile organic compound (VOC) plume located in the vadose zone below the subsurface disposal area at the complex. To date, the system has been operated for two periods, a two-week test and a four-month test. The purpose of the two-week test was to determine what would be extracted from the borehole and to verify the design of the system to handle what would be extracted.
