ABSTRACT 

This study utilizes 2D Electrical Resistivity Tomography (ERT) to analyze subsurface lithology and characterize aquifers in the University of Benin block of flats area. Through a comprehensive geophysical survey, lithological boundaries and structural features crucial for groundwater exploration are identified. Findings reveal distinct layers with varying resistivity values, indicating potential aquifer formations comprising alluvial deposits, laterite, sandstone, and shale. The research highlights the importance of employing geophysical techniques for groundwater resource assessment, offering valuable insights for effective resource management and exploration strategies.

The results provide significant insights into the subsurface lithology and hydrogeological characteristics of the surveyed region. Moderate to high resistivity values in upper layers suggest potential groundwater storage and movement, while deeper layers with higher resistivities may act as barriers to groundwater flow. Additionally, the study emphasizes the importance of 2D imaging in mapping variations in subsurface lithology and geological formations, facilitating geophysical analysis and interpretation. These findings contribute to a better understanding of groundwater resources and support informed decision-making for sustainable water management practices.
