Zusammenfassung:	Treatment of halogenated hydrocarbon contaminants in groundwater is accompli shed by passing the water through a bed of granular iron (43). An electrical circuit (47) is promoted for providing electrons fo r reducing the contaminant. The circuit may be made usin g a DC supply, by configuring an electrolytic circuit, or by providing a layer of a second metal such as zinc placed next to the iron bed, thereby creating a galvenic circuit.
