Abstract

The provision of portable water has for sometime been a serious problem in the Main Campus of Ahmadu Bello University (ABU), Zaria. A geo-electric investigation employing vertical electrical soundings (VES) using the Ajayi Makinde Two Electrode array was carried out in the Main Campus to determine the groundwater potentials of the area. Results of the VES interpretation reveal that the depth to basement in the Main Campus is variable with values ranging from 10.5 to 42.0 m while the aquifer thickness varied from 4.0 to 32.0 m. The aquifer is thicker at the upper northwestern part of the Main Campus and thinner around the west central part of the Main Campus. Also, the Ajayi Makinde Two electrode which is a new array has proved to be effective and can therefore be used as a geo electric method of prospecting.
