A geophysical investigation involving the vertical electrical sounding (VES) electrical resistivity methods was carried out around Pydibhimavaram Industrial area Srikakulam district Andhra Pradesh. Vertical Electrical Sounding (VES) using Schlumberger array was conducted at thirteen (13) VES stations. The study was carried out with a view to determine the subsurface layer parameters (resistivity's and thicknesses) and use same to categorize the ground-water potential of the study area. The

The interpretation of results showed that major portion of the study area was three layer formations. A vast range of resistivities and their corresponding thicknesses were obtained. Pseudo sections and Geo-electric Sections were generated using Surfer software. The pseudo-sections revealed that the North West (NW) and South West (SW) regions are comparatively more weathered than the other parts.
