GEOELECTRICAL MAPPING AND ITS HYDROGEOLOGICAL IMPLICATION- A CASE STUDY OF AJANOMI COMMUNITY IN ETHIOPE EAST L.G.A

CHAPTER ONE

INTRODUCTION

1.1 Background of the study

It is fact that water level in some part of Ethiope east local government area of Delta state such as Otorho, Aragba, Umutu and using Ajanomi community as a case study at Abraka are not equally distributed when compared to other Southern part of the state like Warri and it’s environ, where all the water level in these zone (Warri South-South and Warri North local government area) are sometimes on the same depth. Thus this is due to the geological structure of each environment and the nature of the hydro-geological behaviour of the region.

       The hydro-geological behaviour of such a region as described by some hydro-geologist (e.g. Uliana, 2012) is the movement distribution of water and the nature of aquifer (type of soil) in that region.

       In this project with the aid of geo-electrical mapping using the Schlumberger arrangement (a vertical electrical sounding) and other computerise analytical procedure had made it possible to know the hydro-geological behaviour of the above name village (Ajanomi–Abraka) in Ethiope east local government area of Delta state Nigeria and its implication.

       These above characteristic of hydrogeology, not only affect the availability of the water in some part of the region but also the quality of water and access to it
