AN APPRAISAL OF SUBSURFACE GEOLOGY AND GROUNDWATER RESOURCES OF OWERRI AND ENVIRONS BASED ON ELECTRICAL RESISTIVITY SURVEY AND BOREHOLE DATA EVALUATION

摘要

The research was aimed at determining the depth to the water table, aquifer thickness and subsurface geology of the study area thus revealing its groundwater distribution as well as its potential as a substitute to the surface water resources. Vertical electrical soundings were carried out in the study area with maximum electrode spread. The Schlumberger electrode configuration technique was adopted. VES data were processed using Shclumberger analysis package.
