摘要: Polluted groundwater systems are very difficult to clean up. In his Perspective, [Lovley][1] charts recent advances towards in situ bioremediation of such using anaerobic organisms. Such organisms, which naturally exist soils, may assist cleaning up hydrocarbons, chlorinated pollutants, and metals. The author concludes that strategies promising but substantial research remains be done before any them can adopted for routine application.
