SUBSURFACE CHARACTERIZATION AND AQUIFER VULNERABILITY IMPLICATIONS IN A TYPICAL KARST ENVIRONMENT OF OGUN STATE, SOUTH-WEST NIGERIA USING INTEGRATED GEOPHYSICAL TECHNIQUES

Abstract

The aim of this work is to characterize and assess the subsurface leachate infiltration in  Papalanto District, South-West Nigeria using Integrated Geophysical Techniques; Vertical Electrical Sounding (VES) and 2D Electrical Resistivity Tomography (2D-ERT) using AGI super-string resistivity meter were adopted for qualitative assessment field investigation.
