Abstract: Groundwater is the water that exists in pore spaces and fractures in rocks and sediments beneath the water table. The need for groundwater has increased tremendously due to the unavailability and the contamination of surface water bodies by the intrusion of saline water and human activities. The geo-electric soundings were carried out in Eleme Port Harcourt, capital of Rivers state in order to delineate the subsurface geo-electric layers and the depth to the aquifer unit for groundwater development. Ten the schlumberger electrode configuration. The Pasi Earth Resistivity Meter used. The sounding curves were classified into five and QQ curves. The quantitative interpretation of the geo-sounding curves by partial curve matching and computer iteration revealed 5 geo-electric layers based on characteristic resistivity ranges. The layers are; topsoil, lateritic sand, sand, coarse sand and clay. The major aquifer units in the area are the sand and the coarse sand formations. Virtually all the VES points are good for groundwater development, because of the dominant sand and coarse sand formations, which is the major aquifer unit in the study area
Description: For the purpose of this research, ten within the study area. These stations were taken at different locations within the study area. The schlumberger array was employed. Current was passed into the ground through a pair of current electrode and the resultant resistance were obtained through pair of potential electrode and then recorded on the resistivity recording sheets. The study was carried out by usingPasi Earth Resistivity meter, measuring tapes, current and potential electrode, crocodile clips and hammers
