Abstract: A Bioenhancement Process for Rapid Remediation of Multiphase Subsurface Contamination
Timothy J. Mayotte
The presence of petroleum hydrocarbons, distillates, and chlorinated solvents in subsurface environments frequently occurs from inadvertent discharges or unlawful release, and can pose a serious threat to human health and the environment. Due to strict environmental regulations, many industries are faced with significant financial and, potentially, criminal penalties associated with releases of these chemicals. In recent years, responsible industries have intensified efforts to remediate subsurface contamination. However, the excessive cost and lack of timely success of traditional remedial options have diminished many industries' willingness to proactively engage in necessary cleanup efforts because the expense of doing so may be prohibitive to the sustained economic health of the in ustry. A new technology that addresses each aspect of subsurface contamination by volatile organic compounds (VOCs) has been developed to minimize the duration and cost of remedial efforts. The Subsurface Volatilization and Ventilation
SystemTM (SVVS) promotes in-situ destruction of contamination by biodegradation, and air circulation to enhance volatilization and vapor capture to reduce VOC mass present in the subsurface as bulk product, aqueous phase and sorbed contamination, and vapors. Because all phases of VOC contamination are addressed simultaneously, the remediation process is greatly accelerated. In addition, because SVVS is simplistic in design and construction, remediation costs are typically well below those associated with more traditional treatment options.
