dc.description.abstract Groundwater exploration and extraction in challenging hard rock formations with inherent heterogeneity is addressed comprehensively in this study through geological, hydrogeological, and geophysical investigations. Hydrogeological studies assess existing borehole recharge rates and provide an overarching groundwater potential assessment. A 1D Vertical Electrical Sounding (VES) survey, employing the Schlumberger method, acquires sounding data analyzed with WINRESIST software to extract groundwater controlling parameters, revealing distinct geoelectric layers and illuminating groundwater and aquifer system structural control. Geological mapping, employing detailed topographical data, revealed the prevalence of granitic rocks exhibiting quartz vein and joint intrusions, primarily oriented in the NE-SW direction. These geoelectric layers encompassed the topsoil, weathered/fractured granite, and fresh granite, each characterized by apparent resistivity values ranging from 14 Ωm to 572 Ωm, 10.0 Ωm to 408 Ωm, and 1468 Ωm to 19,031 Ωm, accompanied by varying thicknesses. Further insights were gained from isopach and resistivity maps at depths of 10 m and 30 m, identifying areas with low apparent resistivity values and substantial overburden. These findings pinpointed zones with potentially high groundwater potential, particularly in the northeastern and southeastern regions. Additionally, the results from the weathered layer analysis aligned with the isopach and resistivity outcomes. Hydraulic conductivity measurements, falling within the range of 7.00 × 10–5 m/s to 4.31 × 10–4 m/s, confirmed the subsurface materials' capacity to transmit water. Moisture content ranged from 12% to 20%, while infiltration rates varied from 2.675 × 10–4 L/s to 1.259 × 10–5 L/s. Yield test results from three borehole locations yielded production rates ranging from 56.52 m3/day to 364.26 m3/day, although other boreholes returned indeterminate results. Based on the groundwater potential classification, 25% of the area demonstrated high potential, 45% moderate potential, and 30% low potential. Accordingly, the recommendation is to prioritize well or borehole drilling in high-potential areas to ensure optimal water supply management. © 2023 The Authors en_US
