GEO-ELECTRICAL INVESTIGATION OF AQUIFER PROTECTIVE CAPACITY IN KUBWA BASEMENT COMPLEX AREA, ABUJA...

Increased water demand has prompted the exploration of subsurface water resources. As a result, tools for investigating groundwater occurrence and transport have developed. The availability of safe and potable water in a given location is a veritable indicator of a significant contribution to a society's development and growth. The vertical electrical sounding (VES) method is being used to find and delineate subsurface water structures, aquifer protective capacity, and hence estimate the groundwater potential of Kubwa Village, Phase one (1) and Phase two (2) in Bwari local council, FCT Abuja, Nigeria. In total, 18 VES were conducted using the Schlumberger Configuration in various areas of the study region. Ipi2win software was used to analyse and interpret the field data. The curves revealed that there are three to four classes of geoelectric layers in the area. Topsoil layer thickness and resistivity values range from 1.01-2.81 m and 262-1330 ohms, partially/weathered layer thickness and resistivity values range from 1.19–5.01 m and 49.4-154 ohms, partially/fractured layer thickness and resistivity values range from 27.7–128 m and 308-966 ohms, and the fresh basement layer thickness and resistivity values range from infinity and 495-61296 The results of the interpretation have led to the conclusion that the studied region has moderate groundwater potential.
