Groundwater Prospect in a Typical Precambrian Basement Complex Using Karous-Hjelt and Fraser Filtering Techniques

Abstract

Electromagnetic survey was carried out at Ibodi, village, Ilesa in Atakunmosa West Local government area with a view to determining the probable locations for groundwater exploration in the study area. Ibodi falls within latitude 70 35′ 35.21″ North and longitude 40 40′ 48.28″ East. The development and increase in immigrants at Ibodi has necessitated this study. A total of five profiles from North to South directions were occupied. It was discovered that distances (100.0-140.0) m, 40.0 m, 80.0 m and 35.0 m on profiles 1, 3, 4 and 5 respectively revealed fractured zones which are suspected to be the best locations for groundwater prospects in the study area.
