Abstract:

The study investigates aquifer structures in the Agbor region, employing Very Low Frequency (VLF) Electromagnetic data for 3D imaging. The research is prompted by the critical importance of aquifers in maintaining groundwater resources and the environmental repercussions of subsurface conductivity on subsurface conductivity variations, offering valuable insights for effective groundwater management and environmental assessments. The methodology entails designing and executing VLF electromagnetic surveys using a sophisticated VLF receiver along traverses. Rigorous data processing ensures high-quality measurements, including filtering, noise reduction, and signal enhancement. Inversion algorithms convert processed VLF data into resistivity-depth models, forming the basis for 3D representations. Geological data, such as borehole information and surface geology were integrated to refine the imaging process. Results are presented through scatter plots, line plots, and bar charts, showcasing electromagnetic signal variations, refined VLF data, and geological composition. Resistivity-depth models provide nuanced insights into subsurface resistivity variations, enhancing understanding aquifer systems. The findings bear practical implications for sustainable groundwater utilization and environmental studies in the Agbor region, addressing a significant knowledge gap. In conclusion, the materials and methods deployed encompass VLF electromagnetic surveys, rigorous data processing, and integration of geological data. The results offer detailed insights into aquifer structures, supporting recommendations for sustainable groundwater resource management, and environmental assessment in Agbor.
