Geophysical investigation involving the use of electrical resistivity was carried out at LASU, Ojo with a view to mapping out its unconfined aquiferous zone. A total of eight vertical electrical soundings (VES) were taken and the H and K curves were used in matching the graphs. The results acquired from the survey were subjected to iteration software (win Resist) which delineated four geo-electric layers namely: topsoil, sand, sandy clay and clay. The results observed in VES1-4(AA) and VES 5-8(AA`) establish that unconfined aquifer is between the thickness of 0.5m-2.9m with resistivity ranging from 102.1-322.9 (Wm) in both geo-electric sections.
