ABSTRACT
A geophysical investigation involving the electrical resistivity method was carried out at
IkoleEkiti of South Western, Nigeria with the main aim of investigating the area for
groundwater potential of the regolith aquifer.
The objectives are to identify geological structures and aquifers favorable to groundwater
accumulation andalso input geoelectric layers parameters into a software to produce maps of
the subsurface in order todetermine the groundwater potential of the regolith aquifer.
Thirty (30) Vertical Electrical Soundings (VES) using the Schlumberger array with
maximum electrode separation AB/2 of 100m was carried out with ABEM SAS-300
Resistivity Meter. The VES data were presented as sounding curves and interpreted
quantitatively through the method of partial curve matching and 1-D computer assisted
forward modelling. The sounding curves show three layers tofour layers earth models. The
three layer curve are characterized by H and A type which represents altogether about 54%
of the curve types in the study while the four layer models are characterized by KH, KQ,
QH and AH which altogether covers about 46% of the curve type in the study area. The
overburden was assumed to include the topsoil, upper and lower saprolite, saprock, and
weathered basement. The weathered basement is the aquifer type delineated for the area. Groundwater potential
was evaluated from the maps (i.e. overburden thickness, weathered layer thickness,
weathered layer resistivity,and bedrock relief maps) revealing that the Northeastern,
Eastern and Southeastern parts of the study area are the mostpromising region for borehole
development. However, the western region of the study area can also be considered as fair forborehole development.
