The geophysical survey was conducted at the industrial park of Bure and the surrounding area, West Gojam, Ethiopia using vertical electrical sounding. The study aims to map groundwater potential aquifers and to identify and differentiate different geological structures that play a role in groundwater occurrence and movement. Furthermore, the study aimed in determining the groundwater horizons and identification of potential site selection to know the drilling point by interpreting the integration of geological, geophysical, and borehole data. For these, a total of 12 VES points were distributed on 3 Parallel profile lines. The VES data are processed Ip2win, Winreisit, and Surfer and Auto-CAD softwares. The results of the interpretation show that the study area is composed of two aquifers, shallow and deep aquifers. The shallow aquifer is exposed on the Northeast parts of the area within the gravel and highly fractured basalt rock units at a depth of 25 m. The lowest aquifer is found on the Southwest pars of the study area below a depth of 90 m within highly fractured vesicular and scoriaceous basalt. In the study area, the water table ranges from 10 m to 55 m and good groundwater potential gradually increases as the depth of investigation increases especially in the North West regions of the study area. Geological structure found in the study area that controls the movement and occurrences of groundwater and that trends NE-SW and NW-SE directions.
