The remediation of polychlorinated biphenyls (PCBs) in soils and sediments remains a particularly difficult problem to solve. The possibility of in situ degradation by microorganisms has been pursued for many years since this approach has the potential to provide a cost-effective and environmentally sustainable alternative to dredging for treatment of PCB impacted sites. Being hydrophobic, PCBs partition into organic material and accumulate in anoxic environments well poised to support anaerobic dechlorination of highly chlorinated congeners; products of which are susceptible to complete aerobic degradation. Laboratory research over the past 25 years is now leading to new microbial technologies that could soon be tested for treatment of PCB impacted sediments in the field.
