SITE demonstration of the SVVS technology
- Environmental Protection Agency, Cincinnati, OH (United States)
The Subsurface Volatilization and Ventilation System is an integrated technology used for attacking all phases of volatile organic compound (VOC) contamination in soil and groundwater. The SVVS technology promotes in-situ remediation of soil and groundwater contaminated with organic compounds through the injection of air into the saturated and unsaturated zones, and extraction of vapors from the vadose zone. Through this process, volatile and semivolatile organic compounds are stripped from the soil and groundwater. The subsurface circulation of air also increases dissolved oxygen concentrations in the saturated zone, capillary fringe, and vadose zone, thereby promoting aerobic microbiological processes. The contaminated air extracted from the wells can be treated at the surface before being discharged to the environment. The SVVS process was evaluated under the SITE program at the Electro-Voice, Inc. (EV) facility in Buchanan, Michigan. The soils were contaminated with aromatic hydrocarbons, and halogenated and nonhalogenated volatile and semivolatile organic compounds (SVOCs) through discharge into a dry well. Baseline data indicated that approximately 1,000 kg of VOC and SVOC contamination was present in the dry well area soils, principally in a subsurface sludge layer. The developer claimed that their technology would reduce the sum of seven target VOCs by 30% over a one year period.
