The study employed direct current electrical method and physicochemical analyses to evaluate the groundwater quality in Sharada industrial area. The study area is located between longitude 8° and 9ºE and latitude 10° and 12°N spanning over 6 The geoelectrical methods used were electrical resistivity, Induced Polarization (IP) and Spontaneous polarization (SP) using Vertical Electrical Sounding (VES) techniques. Forty-three VES were conducted. Six samples of soil and water sample were analyzed. The results reveal that deeper basement zones [notably locations A (11'53''N, 830'20''E), D4(11'41''N, 830'16''E), and S4(11'52''N, 830'14''E)] possess the most favorable and protected aquifer systems, making them suitable for sustainable groundwater extraction. In contrast, shallow basement zones especially those adjacent to industrial activities exhibit increased vulnerability to contamination, as reflected in the degraded water quality of Samples C(11'48''N, 830'42''E), D(11'53''N, 830'49''E), E(11'53''N, 830'20''E), and F(11'53''N, 830'21''E). The geoelectrical and polarization methods proved effective in delineating safe groundwater extraction zones and mapping subsurface flow dynamics. While most physicochemical parameters fall within WHO/FEPA standards, elevated TDS, TSS, and low pH in select samples indicate localized pollution likely linked to industrial activities.
