This report presents the findings of a geophysical investigation conducted at a landfill site to detect potential leakage pathways. Utilizing advanced resistivity and induced polarization (IP) methods, we aimed to identify subsurface anomalies indicative of leachate leakage.
High-Density Resistivity Survey:
We employed a high-density resistivity system to map variations in subsurface resistivity, identifying low-resistivity zones that may indicate leachate presence.
Induced Polarization (IP) Method:
IP measurements helped detect conductive fluids and delineate potential contaminant plumes.
Data Processing and Analysis:
Using inversion software, we processed the geophysical data to generate 2D and 3D models of the subsurface structure. These models highlighted potential leakage zones and pathways.
2D Profile Analysis:
Our analysis identified several anomalous zones with significantly lower resistivity, suggesting potential leachate accumulation and migration. Correlation with borehole data confirmed the presence of contaminated areas.
3D Model Insights:
The geophysical survey effectively mapped subsurface leakage pathways, providing critical data for landfill management and remediation planning. This approach demonstrated the importance of integrating geophysical techniques in environmental monitoring.
