UVB (Vacuum Vaporization Well) System for Treatment of VOC-Contaminated Soils (1.92Mb)
Abstract This report summarizes the findings of an evaluation of the Unterdruck-Verdampfer-Brunnen
(UVB) technology developed by IEG Technologies (IEG) and licensed in the eastern
U.S. by Environmental Laboratories Inc. (ELI) and SBP Technologies (SBP). This
evaluation was conducted under the U.S. Environmental Protection Agency (EPA)
Superfund Innovative Technology Evaluation (SITE) Program. The UVB technology
was demonstrated over a period of 14 months from July 1994 through October 1995
at the Sweden-3 Chapman Landfill in Sweden, NY. A modified microbial system
employing an in-well biofilter was demonstrated, along with the ENSR/Larsen
Biovault technology and the R.E. Wright Environmental, Inc. In Situ Bioventing
System, as part of a multivendor bioremediation demonstration. The primary objective
of the demonstration was to determine the effectiveness of the UVB process in
reducing the concentrations of six target VOCs in the vadose zone to below New
York State Department of Environmental Conservation Soil Cleanup Criteria (NYSDEC).
The VOCs and criteria are: acetone 0.2 ppm; methyl ethyl ketone 0.6 ppm; 4-methyl-2-pentanone
2 ppm; cis-1,2-dichloroethene 0.6 ppm; trichloroethene 1.5 ppm; and tetrachloroethene
2.5 ppm. After 5.5 months, 65% of the approximately 50 soil samples from both
the vadose zone and saturated zones met the NYSDEC criteria. Seventy percent
met the criteria after 14 months.
