Assessment Of The Aquifers In Some Selected Villages In Chikun Local Government Area, Kaduna State, Nigeria.

Aboh H. O.


The Vertical Electrical Sounding (VES) technique was used to investigate the sub-surface layering in some selected villages in Chikun LGA of Kaduna State with the aim of determining the configuration of the aquifer underlying the region. The result of the interpreted VES data suggests that the area is underlain by three to five layers. The geologic sections derived from the analyzed geoelectric section suggest that the alluvial deposits of sand, silt and sandy clay as well as the weathered and fractured basement rocks constitute the aquifer in the areas. The average thickness of the aquifer was found to be 25m. The geoelectric section generated also suggest that the resistively values of the aquifer components range from 100 Ωm to 250 Ωm for the alluvial deposits to an average of 50 Ωm to 350 Ωm for the weathered/fractured basement formations. Results obtained for the pumping tests and transmissivity values of  boreholes drilled shows that the area’s aquifer are capable of producing at least 0.75l/s i.e. 2.7m3/hr of portable water.
