Abstract
The concept that the electrical properties of a subsurface can be affected by the leakage of contaminants might be applicable for a leakage detection system for petroleum hydrocarbons and landfill leachate. Detection systems using electrical conductivity measurement are advantageous since they are fast and efficient methods which require little data processing in order to obtain accurate and repeatable results. A grid-net electrical conductivity measuring method had been developed as a means of two-dimensional monitoring of leaking contaminants in a target area. In this study, the optimum electrode spacings of a two-electrode sensor were found for leachate and diesel fuel. Then laboratory model tests were performed to evaluate the direct application of a grid-net electrical conduc
