| Affiliation: | Scott B. Wilson is director of Bioreclamation Services for Groundwater Technology Inc. (4080 Pike Ln., Suite B, Concord, CA 94520). He is responsible for overseeing the design and operation of bioreclamation systems for the decontamination of water and soils and directs the operations at the Groundwater Technology Inc. Bioreclamation Laboratories located in Chadds Ford, Pennsylvania, and Concord, California. He received his bachelor's degree from the University of San Diego and his master's degree from the University of Texas at El Paso where he studied applied microbiology and geology.;Richard A. Brown is technical manager for Ground-water Technology Inc.'s Bioreclamation Services (220 Norwood Park S., Norwood, MA 02062) in the northeast and mid-Atlantic United States. During the last 10 years he has been involved in the development of methods using hydrogen peroxide as a source of oxygen in ground water and soils to stimulate indigenous bacterial degradation of petroleum hydrocarbons. He holds a B.A. in chemistry from Harvard University and a Ph.D. in inorganic chemistry from Cornell University. |
| Abstract: | In situ bioreclamation is a proven technology that cost-effectively treats organic contamination in subsurface environments. As a remediation strategy, it reduces both the contamination dissolved in ground water, as well as residual soil-bound contamination. To maximize biodegradation, the technology is applied after conducting laboratory studies. Application of the technology involves infiltrating necessary nutrients to the contaminated subsurface. Results of a specific case study indicate excellent performance with rapid cleanup of petroleum hydrocarbon contamination from soils and ground water. Costs associated with in situ bioreclamation technology showed a savings of approximately 50 percent over simple pump-and-treat technology. Time frame for cleanup was shown to be approximately 30 percent of the projected time frame of simple pump-and-treat technology. |
