Abstract
This study addresses the pressing issue of dumpsite plumes in Umunede aquifers, employing a mixed-methods approach combining Very Low Frequency (VLF) geophysical techniques with traditional groundwater sampling. The research strategy involves systematic geophysical surveys and groundwater sampling across different locations within Umunede. VLF measurements reveal fluctuations in subsurface conductivity, with a notable peak around 35 meters depth, indicating potential contamination zones. Groundwater analysis identifies spatial heterogeneity in pH levels, heavy metal concentrations, and microbial content, suggesting localized sources of contamination. Aquifer characteristics, including permeability and porosity, are also assessed, revealing spatial variability crucial for understanding water movement and storage. The study concludes by providing comprehensive insights into dumpsite plume dynamics, offering valuable data for targeted remediation efforts and sustainable water resource management in the Umunede area.
