Delination of Fault Assisted Aquifer Using Tripotential Wenner Array-technique Around Ita-oniyan Industrial Layout , Akure, Nigeria

Abstract

Concealed fault assisted aquifer has been located by the tripotential resistivity survey with Wenner electrode configuration. The interpretations of data acquired were made in terms of comparison of the filtered and unfiltered Wenner alpha-apparent resistivity space sections, ratio profiles and computer aided qualitative interpretation of the alpha-apparent resistivity curves. The results of the study demonstrated that in order to be able to site borehole for underground water supply for both domestic and industrial uses in the study area, the well will have to be located along observed bedrock depression of high degree of fracturing, jointing and fissuring which will provide secondary porosity and permeability of the underlying crystalline bedrock. Although, high resistivity contrast of resistivity values at large electrode spacing seems to make the interpretation of the space sections and ratio sections difficult, filtered data however ensure a reasonable data integrity.
