Developing groundwater resource is the best option for safe, reliable, and cost-efficient water supplies to these dis- persed communities. In this study, nine 2D ERI profiles were carried out with the Schlumberger array in eight communities underlain by the crystalline basement rocks in the Bole District of the Savannah Region of Ghana. The aim was to delineate the aquifer zones and select points for groundwater ex- traction. Nine boreholes were drilled from the selected points. The yield was found to vary from 12 to 180 l/min with a depth range of 50 to 70 m. The weathered and fractured zones together with the bedrock topography were clearly marked. It is evident that the 2D electrical resistivity technique is use- ful tool in determining the availability of groundwater in weathered and fractured crystalline environment.

Introduction The demand for water for domestic, industrial, and agricultural use the world over continues to increase due to increase in population size. In most developing countries including Ghana, accessing potable water for domestic use for instance is a major challenge, particularly, to rural dwellers and in some instances cities as well. As a result of this challenge, most people source water from streams, How to cite this paper: Aning, A. A., Sarfo, C. K., Mainoo, P. A., & Noye, R. M.
