Groundwater Exploration in Granitic Rock Formation Using Electrical Resistivity and Induced Polarization Techniques

Abstract

Electrical resistivity and induced polarization surveys have been conducted for groundwater exploration at granitic formation. This study discusses the earth materials resistivity and chargeability of granitic for groundwater exploration at IIUM campus. In this study Terrameter model LS2, cables, electrodes, cable connectors, battery and remote cable were used as the tools for measurement. The spacing between electrodes is 5 m and maximum length of spread line is 400 m by using Pole-Dipole protocol. By comparing the resistivity values and the chargeability values, it would be able to provide better interpretation for ground water exploration for granitic rock. The result also shows the important of chargeability to verify the resistivity value for locating the groundwater position.
