B. Mishra Lecturer, Government Polytechnic, Koderma Dept. of science and technology, Nepal House, Ranchi ABSTRACT The groundwater scenario of residential areas is very critical due to imbalances between recharge and exploitation. Built-up pattern of residential areas restrict rain water to percolate into sub-surface for recharging of groundwater. A large amount of rain water is lost through run off in dense populated areas due to absence of rain water harvesting structures at appropriate locations. Two dimension Electrical Resistivity imaging of sub-surface has emerged as a useful tool for various applications. Electrical Resistivity Imaging (ERI) of shallow sub surface has been carried out along southern and eastern margin of a commercial apartment (under construction) near Krishi Bazar Samatee in dense built up areas of Jhumari Telaiya town for identification of appropriate site of rain water harvesting structure. The ERI of both sites indicates that of fractured and weathered zones are present in sub-surface. The ERI reveals that resistivity of hard and compact rocks are more than 300 ohm-meter. Weathered or fractured rocks have resistivity lower than 300 ohm- meter. Geologically, quartzite occurs in and around study area. Eastern Margin is highly fractured and weathered in comparison to southern margin. Therefore, weathered and fractured part in ERI has been selected as ideal site for construction of recharge well to divert roof top rain water into sub surface for artificial recharge of groundwater.
