Limited capacity of fresh water in some areas in Indonesia made some regions had drought problem or lack of surface water. One of the solutions was increasing ground water used. This research aimed to identify aquifer and the pattern of ground water flow and also to determine potential of groundwater reserved in Dusun Ngantru. The result would be use to find the right location to be used as groundwater wells. The method used in this research was geoelectric method. This method was used to determine the condition of aquifer and rocks under the soil and to define hydrogeological condition of Dusun Ngantru.The analysis results can be used as a reference of where and what kind of groundwater runs underneath, in order to be optimally utilized. The results of hydrogeological studies and the distribution of aquifer showed that there were unconfined and semi aquifers. The direction of the groundwater flow in the study site varied greatly as the lithologic arrangement varied just as much. In the study locations there were Ledok formation, Mundu formation, and Lidah formation. Groundwater potential ware predicted of 55.33 m3/day or 0.64 lt/s. Based on water quality standard in Indonesia, the water quality of wells were classified as first class quality.
