Investigation of Aquifer by Electrical Resistivity Method

Water present below the Earth surface is called as ground water, which has rainfall as its main source. Ground water that accumulates between rock layers is termed as aquifer. Depth of aquifer can be found by using various geophysical methods. Electrical resistivity method is prominently used for finding out depth of aquifer of which Schlumberger Electrical Resistivity was used in Naigaon village of Tal-Purndhar in Pune district. In this paper the author has presented and interpreted ground water condition, depth of aquifer in summer season, subsurface geology. Field survey was carried out to study different rock forms in vicinity and collected information related to lithology. After the thorough investigation by ERM confined aquifer was found to be present at depth of 45m to 75m.
