A Heuristic Evaluation of the State of Groundwater Using Electromagnetic Method
The Electromagnetic (EM) geophysical method was used to assess the groundwater condition of the Oloruntedo community in Obantoko, Odeda Local Government of Ogun State, to delineate the most prolific aquifer unit within the study area. This study presents a heuristic evaluation of ground water yield. Six (6) EM transverses or profiles were established across the survey area. The survey was run close to existing boreholes and hand-dug wells to vividly imprint the fracture and the weathered zone using PQWT-TC150 geophysical water detector equipment. The hydrogeologic significance of the surveyed area delineates the groundwater architecture within the traverses. The results obtained from this study produced curve graphs and subsurface profile maps of each transverse location. It was observed from the result that EM profile 1, 3, and 6 has a high groundwater potential with varying aquifer depth, while EM profile 4 and 5 imprint a low groundwater potential zone.
