Abstract

Nine vertical electrical sounding (VES) points were selected out of cultural interferences in Anghido and Environs part of Jema’a sheet 188 SW, Central Nigeria using the Schlumberger array to ascertain the groundwater potentials of the area. The field data curves were typical of KH, A, Q, H and QH types. These were subjected to quantitative interpretations after curve matching using IXID software. The qualitative interpretations from the quantitative result were undertaken using Golden Surfer 8 Computer software. The result of the quantitative analysis gave five to six geoelectric layers consisting of topsoil being clay/sand 300-1500Qm and 0.14-3.2lm, s; lateritic hard pan 216-1615 Qm and 0.8-5.81m, weathered rcgolith43-51' fractured basement 40-902Qm 8.22-53.46m, partially fractured basement 482-1142 Qm and 5.47-11.69m and fresh basement 1142-2048 Qm and infinite depth as their corresponding resisitivities and thicknesses. The main aquifer formations are the sandylateritic, weathered/fracture basement and partially fractured basement. The qualitative results include geoelectric section, piezometric map, true aquifer resisitivity map, depth to basement map, surface elevation map and Basement resistivities map were produce for Anghido and Environs. The groundwater potential ranges from good, moderate and fair categories. The generally groundwater potential varied from location to location. This work is useful for rural water planning and development at Anghido and Environs.
