Abstract: A geophysical study comprising vertical electrical soundings was carried out in four (4) locations (Udi 1, Udi 2, Udi 3 and Udi 4) in Udi L.G.A. to assess groundwater potentials. The method involves the use of resistivity equipment (ABEM Terrameter), the field data were obtained utilizing Schlumberger configuration. The WINRESIST software was utilized in the data processing. According to the study’s findings, the geological formations present in these locations contain five to seven layers. Layers 1 has resistivity values ranging from 158.1 – 418.1 m at depths of 0.6 – 1.6 m, layer 2 has resistivity values ranging from 1103.9 – 41387.3 m at depths of 0.8 – 8.9 m, layer 3 has resistivity values ranging from 313.0 – 4782.9 m at depths of 6.9 – 28.2 m, layer 4 has resistivity values ranging from 1847.9 – 6956.8 m at depths of 11.8 – 154.6 m, layer 5 has resistivity values ranging from 115.0 – 2838.4 m at depths of 101.2 – 219.2 m, layer 6 has resistivity values ranging from 51.1 – 261.7 m at a depth 190.6 m, and layer 7 have a resistivity value of 47.1 m at an unknown depth. Layer 4 from all locations shows a prolific aquifer where enormous groundwater can be explored due to its high resistivity values, depth and thickness. The aquifer is estimated to be at the depths of 90.0 – 120.0 m. The results of this geophysical examination revealed that the studied region has good groundwater potential, which if properly utilized, will go a long way toward alleviating the effects of water insufficiency in Udi L.G.A.
