Abstract

Research of the groundwater in Pakel, Bandung and BesukiSubdistricts, Tulungagung District has been implemented. The research area is located in the rice field area, previously an area of annual flooding inundation during the rainy season. This situation troubles the community and local government of Tulungagung District. During the dry season, the mud cracks, making it difficult as agricultural land. The research was done using Geoelectrical Resistivity Schlumberger configuration method. The measurement point is located in the three Subdistricts with a total of 19 measurement points. The study location is at 111.75988880EL; -8.2264166670 SL to111.84541670 EL; 8.1309166660 SL or covers an area of 101km2. The length of the track used is a maximum of 600 meters. Based on the results of the geoelectrical resistivity data, it was found two types of aquifers, which are open aquifers in depth ranging from 6 m to 21 m and a confined aquifer in depth ranging from 90 to 115 m. In addition to the geoelectrical information data, drilling was done at an accessible point by heavy equipment in the Gempolan Village, PakelSubdistrict. At the drilling point, artesian wells were obtained at a depth of 108 meters and can rise to 2 meters above the soil surface. The discovery of artesian wells is then used by residents to meet the needs of clean water considering that in this area most wells are smell and iron contain.
