Abstract

 An integrated electromagnetic and geo-electric study was carried out in some parts of Kusa Mountain, Ijero Ekiti, Southwest
Nigeria. Very Low Frequency Electromagnetic (VLF-EM) profiling was measured along eight traverses from which
conductive (fractured) zones were established. This enabled the location of 10 points at prominent fractured zones where
vertical electrical sounding (VES) were conducted to further reveal the geo-electric parameters. The electromagnetic and
geo-electric parameters were analysed, processed and modeled with relevant software in order to obtain the spatial
distribution of the groundwater. From the groundwater potential map, the study area was rated as low, moderate and high
groundwater potential. This study showed that central to eastern region fell within high groundwater zone. The region
around VES 8 and 9 (northeastern flank) was rated as moderate while the remaining part is rated as having low groundwater
potential. It is recommended that future exploration and exploitation work for groundwater resources should be concentrated
around region rated as having high groundwater potential
