Hydrogeological and Geoelectrical Propecting for Groundwater Within parts of Northeastern Bosso, Minna, North-Central Nigeria Region

Abstract

This work employed static water elevation data to delineate areas where hand-dug wells are seasonally productive from areas where they are continually productive in parts of northeastern Bosso, Minna. It also integrated low resistivity anomaly with data on electrical anisotropy, longitudinal unit conductance and transverse unit resistance to identify areas with deep water bearing fractures. A large number of boreholes have been completed in the shallow fractures, and this has resulted in seasonal production from the shallow aquifers. Hand-dug wells within the groundwater convergence zone established in this work were found to produce water continually. while those located around the established groundwater level ridges are seasonally productive. The groundwater convergence was found to exist within the central portion of the study area, where the work revealed high surface fracture density values (2.4 to 3.0m) and surface fracture permeability values (0.0003 to 0.00046m²). Deep fractures with optimum attributes for water production were found in the north-western and north-eastern portions of the study area, within latitudes N9.645 to N9.665.
