ABSTRACT
This study focuses on evaluating the groundwater potential in Pompo Village, Gidan Kwano, Minna, through the
application of Vertical Electrical Resistivity Sounding (VERS) technique. Groundwater availability and accessibility are
vital for sustaining rural communities, and the VERS method offers a non-invasive approach to understanding
subsurface geological structures. By analyzing the electrical resistivity variations in the subsurface, this study aims to
delineate potential aquifer zones, depth to water table, and lithological variations. The findings provide essential
information for informed water resource management and sustainable development in the study area.

The VERS technique involves measuring the electrical
resistivity of the subsurface materials at varying
depths. It provides valuable insights into the
lithological composition, water table depth, and the
presence of subsurface structures that may influence
groundwater occurrence. By utilizing this technique,
the study aims to delineate areas with promising
groundwater potential in Pompo Village, contributing
to sustainable water resource management and
community development.

hydrogeological
considerations.
Ensure a representative distribution of survey points
across the study area.
VERS Data Acquisition:
Utilize a resistivity meter and electrodes to measure
the apparent resistivity of the subsurface materials.

RESULTS
The assessment of groundwater potential in Pompo
Village, Gidan Kwano, Minna, using the Vertical
Electrical Resistivity Sounding (VERS) technique has
yielded significant insights into the subsurface
geological structures and aquifer zones.
Subsurface Resistivity Models: The VERS data
processing and inversion have generated subsurface
resistivity models that depict variations in electrical
properties with depth. These models reveal the
presence of distinct geological layers, including
potentially porous and permeable aquifer formations.
Aquifer Delineation: Analysis of the resistivity models
has led to the identification of areas with lower
resistivity values, indicating the potential presence of
aquifer zones. These regions are characterized by
enhanced water-bearing properties, suggesting the
likelihood of groundwater occurrence.
Water Table Depth: By correlating resistivity changes
with borehole data and hydrogeological information,
the depth to the water table has been estimated. This
information is crucial for understanding the
accessibility and sustainability of groundwater
resources in the study area.
DISCUSSION
The results indicate promising groundwater potential
in specific zones of Pompo Village. The observed
variations in resistivity are indicative of subsurface
lithological changes that could influence groundwater
availability. The identified aquifer zones align with
existing geological information, validating the VERS
technique's ability to provide accurate subsurface
insights.
Furthermore, the estimated water table depth
provides valuable information for well design and
borehole placement, optimizing water extraction
strategies for community use.
CONCLUSION
In conclusion, the application of the Vertical Electrical
Resistivity Sounding (VERS) technique has proven to
be an effective approach for assessing groundwater
potential in Pompo Village, Gidan Kwano, Minna. The
results highlight specific areas with favorable
conditions for groundwater occurrence, thereby aiding
in informed decision-making for sustainable water
resource management.
The insights gained from this study contribute to the
broader understanding of hydrogeological conditions
in the study area, enabling better planning and
allocation of water resources for community
development. The successful utilization of the VERS
technique underscores its value as a non-invasive and
cost-effective tool for groundwater exploration and
assessment.
