ABSTRACT

This study was carried out to identify shallow aquifers in a number of villages in Southern Ughelli North and the Patani Local Government Area of Delta State, in Southern Nigeria, using vertical electrical sounding (VES) with the Schlumberger electrode configuration. A total of 12 VES surveys were performed, employing the Schlumberger configuration with a maximum electrode spacing of 150 meters. Deductions from the following aquifer resistivity, aquifer depth, transverse resistance, aquifer thickness, longitudinal conductance (S), transmissivity, and hydraulic conductivity were measured using primary geo-electric parameters. The values of the aforementioned parameters range from 500 to 700 Ωm, 13 to 25 m, 500 Ω·m² to 9000 Ω·m², 10 to 20 m, 0.001 to 0.2, 0.77 to 60.675 m2/day, and 0.077 m/day to 5.04 m/day respectively. Aquifer across the study area was categorized based on varying degrees of polluted source susceptibility using the principal geo-electric characteristics and the geographical distribution of S. Aquifer vulnerability was investigated using the longitudinal conductance values, and the research region was classified as moderate, weak, and poor based on the aquifer protective capacity assessment.
