study was carried out to investigate the groundwater potential and aquifer
characteristics of locations in Igun, Eku and Oria in Delta State, Nigeria.
Nine vertical electrical soundings using the Schlumberger configuration were
conducted to assess the geoelectric properties of the subsurface, while
down-hole loggings and pumping test were employed to evaluate the aquifer characteristics
of the area. The geoelectric data were interpreted by partial curve matching
and computer iteration techniques to determine the resistivity, thickness and
depth of the subsurface formations. The result revealed the presence of four
geoelectric layers comprising of lateritic/loamy topsoil, clay, fine-medium
grain sand, and coarse sand. Analysis of the geoelectric interpretation
indicates that the third and fourth layers are water bearing horizons. Result
further indicates that the fourth layer with a resistivity range of 2212 to
7148 Ωm and depth range of 24.7 to 31.9 m is more prolific than the third layer
aquifer. The result of hydrogeological investigation showed that the electrical
conductivity of the groundwater aquifer in Igun, Eku and Oria are 0.028, 0.032
and 0.024 mS/m respectively, while their corresponding total dissolved solid are
91.08, 95.92 and 79.53 mg/m3. The result also showed that the
transmissivity of the groundwater in Igun, Eku and Oria are 0.0728, 0.0873 and
0.0679 m2/min respectively while their corresponding storativity
were obtained as 3.21
× 10-4, 4.71 × 10-4, and 2.87 × 10-4. These
results obtained from the three locations have shown that the groundwater
aquifer is reliable in terms of quality and yield as they conform to international
