Abstract

Geoelectricity is one of geophysical methods performed by injecting electric current into the earths. This research objected to map aquifers using geoelectric with Schlumberger electrode configuration consisting of 4 sounding points. The results are then processed with IP2WIN software which yields a real resistivity map as a function of depth. The correlation of sounding points produces three-dimensional real resistivity maps. The results of this study located at a housing estate, Mataram, West Nusa Tenggara, consists of 4 sounding points show that the aquifer is have huge amount of fresh water The aquifer layer in this area is a free aquifer. At point PA1 the depth of the aquifer starts from a depth of 81.4 – 125 meters; PA2 point at a depth of 80 – 124 meters; PA3 point at a depth of 91.8 – 118 meters; and Point PA4 at a depth of 47.4 – 113 meters
