Geophysical investigation of subsurface lithology and aquifer distribution was done using Schlumberger array in Edjekota, Ughelli North LGA of Delta State This community is prone to annual flooding resulting in massive deposition of materials over many years thereby creating problem of potable water. This problem of potable water has increased in recent time due to increase in population density, petroleum exploration activities and spillages along the creeks. Thus, ten Vertical Electrical Soundings (VES) were made using Schlumberger array in Edjekota
Delta State to obtain geophysical field data in order to investigate the occurrence of groundwater in relation to the depth and thickness of viable aquifer. The field data measured from SAS 1000 terrameter were plotted in a bi-log graph to obtain sounding curves. The curves were analyzed and iterated. The qualitative results showed that Edjekota has homogeneous subsurface stratification with AAK, KHAA, AKHA and KQHQ curve types. The generated geoelectric sections have five to six sub-layers to a depth of over 70 m with hugh loose sand deposits
beneath in Edjekota. Although water seems to be everywhere in Edjekota, prolific aquifer is within 30 – 50 metres.
