Abstract
Laboratory experiments were performed on carefully prepared soil layers to investigate the sensitivity of the electrical resistivity of cone on water content and different types of contaminants including heavy metal and petroleum hydrocarbon. Theoretical resistivity equation considering the electric current flow in 3-dimensional full-space around the cone was derived to provide a means of computing the geometric factor for diameter of cone and electrode spacings. Laboratory model test results showed that electrical resistivity measured by cone showed high applicability to be used in detecting the heavy metal contamination in the saturated subsurface and the diesel fuel plume floating above the groundwater table, though it might be difficult to detect contamination in the unsaturated layer.
