This volume includes articles that describe advanced technologies for promoting and monitoring bioremediation of media, including wastewater, landfill leachates, and low-permeability soils. Among the bioremediation technologies described are bioslurry and vapor phase reactors and the application of alternative electron acceptors. Molecular monitoring, environmental statistics and modeling, and bioavailability assessment are discussed as means of designing and tracking remediation projects. Case histories of bioremediation projects and bench-scale to full-scale interpretations are provided.
