Detection of groundwater sources in Lembor village using geoelectrical resistivity method schlumberger configuration

Abstract Drought is one of the problems faced by people Lembor Village, Lamongan Regency, this problem will be slightly resolved if area has reserves groundwater sources. Therefore, study aims to determine existence potential sources around Village. The method used geoelectrical resistivity schlumberger configuration. Data acquisition was carried out for 10 measuring points Vertical Electrical Sounding (VES) with a track length 310 meters, and distance between electrodes meters. measurement results are then correlated VES produce 2-dimensional cross-section. showed that measured value 0.03 Ωm 81.1 Ωm. structure subsurface layer dominated clay limestone. indications presence found at depth 25 35 meters 45 170 180 270 280 values 0.32 need investigated in wider area, distribution direction flow.
