ABSTRACT

Electromagnetic and electrical resistivity geophysical methods, were used to map out potential groundwater sites for boreholes drilling in the Adoe community in the Sunyani west district of Ghana. The electromagnetic data was taken with the Geonics EM-34 conductivity meter while the electrical resistivity data was taken with the ABEM SAS 1000 C Terrameter using the Schlumberger electrode configuration. Results from the measurements revealed four subsurface geological layers of the following resistivity and thickness ranges: quartzitic sandstone with clay (42-118 Ωm, 1-2.2 m); sandy clay with silt (27-487 Ωm, 9-12 m); lateritic sandstone (13-728 Ωm, 6-14 m); and clayey shale (20-29 Ωm, 6-14 m), The overburden ranged in thickness from 14 m to 24 m. Sites selected for borehole drilling had a groundwater yield range of 0.94 -12 m3/h.
