The success ratio is low in drilling well. In order to reasonably develop groundwater resource, the three electrical exploration lines were arranged in the direction perpendicular to main geology structures based on the hydrogeological investigation in the working site. The apparent resistivity values were observed by means of the resistivity sounding with the symmetric quadrupole along the lines.
