A series of environmental technology field tests, including in situ bioremediation, are being conducted at the Savannah River Integrated Demonstration (SRID) site near Aiken, South Carolina. This site is part of a larger area that was used to process fuel and target elements for use in reactors. Degreasing operations were included at several stages of the operations. Degreasers such as TCE and PCE were discharged to a seepage basin via a process sewer pipeline. In the early 1980s, inspections revealed that the process sewer line had extensive cracks, allowing solvents to leak into the subsurface environment. An in situ remediation technology designed to address this linear source term was tested in 1990. This technology involved air injection below the water table and vacuum extraction in the vadose zone using two horizontal wells [Looney et al., 1991]. Bioremediation experiments using these same horizontal wells were begun in 1992 [Hazen, 1992a]. This reports describes the experiment, which is based on the expectation that the injected air and methane will stimulate the growth of naturally occurring methanotrophs at the site and these bacteria will co-metabolize the chlorinated solvents.
