The concept that the electrical properties of subsurface material can be affected by the introduction of contaminants might be applicable fur developing the leakage detection system for petroleum hydrocarbons of underground storage tanks and leachate coming from landfill. Investigations were conducted with diesel, NaCl solution, and leachate by laboratory tests. Simulation test was performed leaking at a certain point in the field. The measured resistance was exponentially decreased as the water content of uncontaminated unsaturated sand was increased. The resistance of soil was increased by diesel but decreased by NaCl solution or leachate. The optimum electrode spacings were found for NaCl solution, leachate and diesel. Electrolytic solutions were better detected by wider spacing than non electrolytic solution.
