Abstract: Nitrate migration to ground and surface waters is a serious U.S. contamination threat. Electro-osmosis may be a more effective means for soil reclamation than leaching or chemical treatment. A field lysimeter was constructed to evaluate use of electro-osmosis to concentrate nitrates in and remove nitrates from soils. Tests are being conducted using different electrode materials and electrical voltages.
