Sinkholes are a global challenge, and several countries are affected by them. Timely identification of sinkholes and monitoring of subsurface soil conditions are highly important. However, the main challenge for different countries lies in the methods of preventing and mitigating sinkholes. Accordingly, considering the distribution of sinkholes in various countries, this paper addresses the...
This study evaluates groundwater vulnerability and contamination in Osubi and surrounding communities, Delta State, Nigeria, using an integrated geophysical, hydrogeological, and geochemical approach. The investigation combined 1D, 2D, and 3D electrical resistivity surveys (21 Wenner–Schlumberger profiles and 38 VES), ten MASW seismic traverses, hydrogeological data from fifty hand-dug wells,...
Rapid population growth and urbanization have accelerated waste accumulation, pushing the biosphere beyond its natural regenerative capacity under the prevailing linear “take–make–use–dispose” model. Transitioning to a circular economy is essential for mitigating environmental degradation. This study aims to identify environmentally harmful yet abundantly available waste materials that could...
This study employs electrical resistivity methods—Vertical Electrical Sounding (VES) and 2D Electrical Resistivity Imaging (ERT)—to delineate subsurface peat and clay deposits in Orile Whitesand, Orile–Iganmu, Lagos State, Southwestern Nigeria. A total of twenty-four (24) VES and eight (8) 2D resistivity profiles were acquired using a PASI Terrameter (Model 16GL). The Schlumberger array was...
This study presents an integrated geologic, petrographic and hydrogeochemical assessment of groundwater resources in the Waru area of Apo (FCT), Abuja, North-Central Nigeria. The objective was to characterize lithological units, evaluate groundwater chemistry, determine heavy metal concentrations and assess potential environmental and health implications. Field mapping and petrographic...
This study investigates groundwater contamination and aquifer vulnerability in the Ifewara area, Southwestern Nigeria, through an integrated geophysical and hydrochemical approach. Vertical Electrical Sounding (VES) was employed to characterize subsurface stratigraphy, while Atomic Absorption Spectrometry (AAS) analyzed trace metal concentrations in groundwater from five boreholes and five...
