(Augmented In Situ Subsurface Bioremediation Process)
The Bio-Rem, Inc., Augmented In Situ Subsurface Bioremediation Process uses a proprietary blend (H-10) of microaerophilic bacteria and micronutrients for subsurface bioremediation of hydrocarbon contamination in soil and water (see figure below). The insertion methodology is adaptable to site-specific situations. The bacteria are hardy and can treat contaminants in a wide temperature range. The process does not require additional oxygen or oxygen-producing compounds, such as hydrogen peroxide. Degradation products include carbon dioxide and water.
The bioremediation process consists of four steps: (1) defining and characterizing the contamination plume; (2) selecting a site-specific application methodology; (3) initiating and propagating the bacterial culture; and (4) monitoring and reporting cleanup.
This technology treats soil and water contaminated with hydrocarbons, including halogenated hydrocarbons.
This technology was accepted into the SITE Demonstration Program in winter 1991. The technology was demonstrated at Williams Air Force Base in Phoenix, Arizona from May 1992 through June 1993. The Demonstration Bulletin (EPA/540/MR-93/527) is available from EPA. Bio-Rem, Inc., has remediated sites in Illinois, Michigan, Indiana, Texas, Kentucky, Ohio, Arizona, Connecticut, Florida, Georgia, Vermont, Oklahoma, Virginia, Nevada, California, Missouri, and Washington.
