Abstract
A geoelectrical survey employing the conventional
Vertical Electrical Sounding (VES) was carried out at 36
stations in the Basement Complex of Romi village, south of
Kaduna town. The survey was carried out to determine the
groundwater potentials of the area.
Results from the interpretation of the data collected
led to the production of some geoelectric and geologic
sections and maps from which conclusions were drawn. The
result of the study indicate a layering of two to three in
the region. The range in resistivities for the first, second
and third layer are 95-2187 ohm-m, 32-558 ohm-m and 585-8810
ohm-m, respectively depending on the lithological formation.
The investigation showed that the aquifer occurs in the
weathered and fractured basement which is characterized by
relatively low resistivity values, 35-160 ohm-m for the
weathered basement.
From the analysis of the maps and other information in
the study, the most promising region for underground water
exploitation in the area was delineated and this was found
to be the region around VES L3/3. The dimension of this
region measures about 1.68 xlO6 nr3 . Furthermore, the
overburden thickness map suggests that the drainage pattern
in the Romi stream is controlled by the basement topography.
