Polluted groundwater systems are very difficult to clean up. In his Perspective, Lovley charts recent advances towards in situ bioremediation of such systems using anaerobic organisms. Such organisms, which naturally exist in soils, may assist in cleaning up hydrocarbons, chlorinated pollutants, and metals. The author concludes that anaerobic strategies are promising but that substantial research remains to be done before any of them can be adopted for routine application.
