Subsurface volatilization and ventilation system (SVVS) (trade name): Innovative technology evaluation report
Technical Report
·
OSTI ID:187120
This report summarizes the findings of a Demonstration Test of Brown and Root Environmental`s Subsurface Volatilization and Ventilation System (SVVS) process. Under the SITE program, the technology was evaluated to determine its effectiveness in reducing volatile organic contamination in the vadose zone of the former `dry well area` of the Electro-Voice facility after one year of treatment. The SVVS process is an integrated technology that utilizes the benefits of soil vapor extraction/air sparging and in-situ bioremediation for the treatment of subsurface organic contamination in soil and groundwater. Demonstration results showed that the SVVS achieved an overall 80.6% reduction in the sum of the seven critical VOCs in the vadose zone, exceeding the vendors claims. Reductions of 81.5% were achieved in the `sludge` layer, and between 97.8% and 99.8% for the other vadose zone layers.
