ERT

FEG conducted Electrical Resistivity Tomography (ERT) geophysical investigations to evaluate subsurface conditions, identify geological variations, and map potential groundwater zones and buried features. The survey was carried out using electrical resistivity measurements collected through an array of surface electrodes, followed by data processing, inversion, and interpretation to develop subsurface resistivity profiles.

Scope of work included:

Survey planning and selection of suitable ERT survey lines based on site conditions and investigation objectives.

Deployment and configuration of electrodes along designated survey profiles.

Acquisition of electrical resistivity data using controlled current injection and voltage measurements.

Measurement of subsurface resistivity variations across the investigated area.

Data quality control, processing, and inversion to generate two-dimensional resistivity sections.

Interpretation of geological layers, subsurface anomalies, weathered zones, and potential groundwater-bearing formations.
