Abstract:
An apparatus for treating an in situ flow of ground water containing contaminants, the apparatus comprising:first and second permeable metal electrodes, wherein one of said first and second permeable electrodes is a positive electrode and the other is a negative electrode; and a power supply coupled to each of the first and second permeable electrodes to create an electrical potential therebetween, the first and second permeable electrodes being disposed in situ within the flow of ground water containing contaminants with the first permeable electrode upstream from the second permeable electrode and the water containing contaminants flowing through and between the permeable electrodes, the permeable electrodes being spaced a select distance to promote an electric current in the water containing contaminants between the electrodes sufficient to sustain oxidation or reduction of The contaminants in the vicinity of the electrodes, whereby oxidation of the contaminates occurs in the vicinity of the positive electrode and reduction of the contaminants occurs in the vicinity of the negative electrode; wherein said flow of water is equal to a rate of flow of the groundwater.
