Abstract: | Ajebo Foursquare Camp was surveyed to locate sites for water supply tube-wells and to adduce reason(s) for failure of most boreholes drilled there. Results from twenty four (24) VES points show 3–4 geoelectric layers, which are weathered/Fractured rocks of resistivity range from 68–394Ω m with thickness range of 3.4–14.8m. Only two VES stations have aquifer thickness above 14m. However, results of eight (8) 2D resistivity imaging in the areas show about two points where productive boreholes could be sited. These points were not covered during VES survey. Thus, tomography/2D resistivity imaging gives a better lateral view of the subsurface layers than geoelectric section from 1D because of its ability to give a continuous record of subsurface image. |
