Groundwater exploitation is generally considered as the only realistic option for meeting dispersed rural population water demand. Availability of potable groundwater has been a major problem in Uromi, Esan North East of Edo State. Evaluation of geophysical and chemical characteristics is essential for the development of groundwater resources in the area.

To study groundwater potential in the area, Schlumberger Electrode Configuration and the IP2WIN method of interpretation was adopted. The SAS300B ABEM Terrameter was utilised for the acquisition of data and the global positioning system (GPS) was used to map out various vertical electrical sounding stations in the area. Geochemically, 5 samples of groundwater were taken and subjected to physical and chemical analysis using WHO drinking water standard method. The results from the field and laboratory analysis revealed evidence of pollution from both physical and chemical sources. Five Vertical Electrical Sounding data were acquired in order to evaluate groundwater geophysically within the locations in Uromi. Expectantly, water bearing formations (aquifers) were found in some of the locations such as St. Theresa Catholic Church, Ukoni and Esan Model Boys Grammar School Ubierumum-Oke, with GPS Co-ordinates N060 43.019’ E0060 21.470’ and N060 40.997’ E0060 17.354’ at depths of 32.43 meters and 69.90 meters below the earth surface respectively. This study therefore reveals the following: that the selected hand dug wells in Uromi is not safe for consumption because of high nitrite which was above the permissible limits recommended by WHO for drinking water. It was further established that the wells were polluted in areas nearer to farm lands than areas further away from them.
