Abstract
This study applied Direct Current Resistivity, Induced Polarization (IP), and Self-Potential
(SP) geophysical methods to evaluate the aquifer characteristics in Hotoro Kudu,
Nassarawa Local Government Area, Kano, Nigeria. The study area covers approximately 5
km² and lies between latitudes 11.96001°N and 11.98005°N, and longitudes 8.57002°E and
8.59000°E. The acquired geophysical datasets were subjected to reduction, processing, and
interpretation, which enabled the delineation of prospective zones for groundwater
exploration.The identified groundwater targets are situated between latitudes 11.96700°N
and 11.97000°N with longitudes 8.58600°E to 8.58820°E, as well as latitude 11.97100°N
and longitude 8.58850°E. The estimated aquifer depth within these zones ranges from 100
m to 130 m. The very low IP values suggest the presence of unconsolidated sediments
characterized by appreciable porosity and permeability, indicating a high recharge potential
and, therefore, a sustainable groundwater resource. Furthermore, the observed range of SP
values reflects variations in groundwater flow, indicating upward and downward movement
through porous and/or fractured formations.Subsurface characterization revealed six distinct
lithological units: Sandy Soil with Clay, Clayey Sandy Soil, Clay, Weathered Basement,
Fractured Basement, and Fresh Basement Complex rocks. Based on the integrated
geophysical interpretation, a drilling depth of approximately 140 m is recommended for
groundwater development within the delineated zones.
