This report provides an overview of in situ bioremediation to remediate chlorinated solvents in contaminated soil and groundwater. It describes degradation mechanisms for chlorinated solvents, enhancements of these mechanisms by the addition of various materials and chemicals, design approaches, and factors to consider when selecting and using the technology. A summary of treatment vendors and nine case studies of field applications are also included.
