Geophysical Site Investigation for Groundwater Prospecting in the Permanent Site of Federal University, Dutsin-Ma, Nigeria

Geophysical investigation of the permanent site of Federal University, Dutsin-Ma located in Katsina State site was carried out with the objective of investigating the subsoil conditions based on geophysical site exploration methodology in order to take precise engineering decisions on the best locations for different utilities and ground water profile establishment. The major instruments used in carrying out the fieldwork include: SAS 300, Reels of cables, sets of electrode, hammer, tapes and sealed battery. Six survey profiles were used with 200m length each. Dedicated geophysical software was used for the data processing. Results show that the thickness of the overburden which ranges between 2 m to 35 m is more in the southern part of the survey area than the northern part that has thin overburden thickness. This suggests that the thickness of the underground water aquifer will be more in the southern part of the survey area. Best locations of boreholes were recommended and alternative source of water was suggested based on observation.Keywords: Fresh basement, Geophysics, Resistivity imaging, Site investigation, Subsoil exploration, Aquife
