A geophysical survey of the University of Benin was carried out using the resistivity method for groundwater investigation. Five (5) vertical electrical sounding (VES) points were taken to ascertain the groundwater availability and depth to groundwater in the area. Areas recording low resistivities had a likelihood of being water bearing and so data collected was interpreted. The VES data indicated that between 5 to 7 layers of soil were encountered ranging from the topsoil to the aquiferous layer. The depths ranged between 106ft to 209ft. The flow direction and depth to water table models generated indicate a lower elevation around the central area and points located around this area would have a higher possibility of a high water yield.
