Abstract:
The hydrogeological studies of Bingham University Karu Campus to ascertain
qualitative and quantitative groundwater potentials through the interpretation of 32
Vertical Electrical Soundings (VES) data of the geophysical investigation with
complementary ADMT isoline maps has revealed three to five subsurface
geoelectric layers and geologic sections, namely: topsoil, clay/silty followed by wet
weathered basement, fractured and fresh basement rocks. The aquifer units in the
study area consist of the weathered basement and fractured layers. The study area's
predominant layer of a weathered basement, which ranges in resistivity from 17
Ω𝑚 to 710 Ω𝑚, was selected as a viable aquifer zone target for groundwater
exploitation. Given the thickness of the underlying aquifers, the indicated zones
have a higher storage capacity and are well-suited to accommodate any potential
future water demand within the university community. The prominent zones found
for groundwater development are VES points A1 – A4, B2, B3, B5, C7, C8 and D5
with depth zones ranging from 15.1m to 130m. Six points failed productivity
evaluation due to the shallow depth and resistive nature of the aquifers in the
regions and discouraged groundwater development.
