The subsurface environment is one important part of human life. People need the clean water from subsurface to fulfill their life. Therefore one needs to know the subsurface area that is free of contaminants to find sources of clean water. Geo electric is one geophysical method can be used to detect the clean water sources. Geo electric investigation done on the basis of the physical property of rock to electrical current. If the flow of direct current into the earth through the electrode currents A and B, then the measured potential difference caused by the current on 2 pieces of electrode potential on M and N, it will obtain the value of resistivity pseudo types. Electrode configuration used in the form of Schlumberger configuration to determine the subsurface clean water aquiver. Interpretation of the results of the formation resistivity shows four layers of formation, which consists of layer 1 with the resistivity of 117-1978 ohm meter (conglomerate), layer 2 with the resistivity of 23-93 ohmmeter (sandstone 2), layer 3 with the resistivity of 1-10 ohmmeter (clay), and layer 4 with the resistivity 17-65 ohm meter (sandstone 1). The possibility of formation that could serve as clean water reservoirs are sandstone1 and sandstone2.
