This research developed the pollution detection technique of the landfill leachate by electorical resistivity monitoring from the viewpoint of the leachate have high electric conductivity. We installed eleven electorical resistivity survey lines in the place where the leachate leaked out below the landfill, and electorical resistivity was measured periodically. The electorical resistivity inversion analyses of two and three-dimensional was carried out using resistivity data of eleven survey lines, and also the electorical resistivity change ratio was obtained by using measured value of resistivity repeatedly. As the result, it was able to accurately grasp the spatial diffusion range of the leachate by obtaining electorical resistivity change ratio of three-dimensional after and before of the rainy season, and it was proven to be an effective method for the pollution monitoring.
