【 摘 要 】

Linear Schlumberger configuration was employed to delineate the formation strata and groundwater distribution in Ifon Edo State, Nigeria with a view to identifying suitable sites for sitting viable boreholes for long term supply of potable water in the town and nearby communities. Ten vertical electrical soundings (VES) were made using Schlumberger array. Six soundings were made along Orin-Oyih river road and four around the quarry. The obtained field data were subjected to analysis and interpretation by conventional curve matching and computer iteration techniques, “the Resist” The results reveal that stations exhibit A, H and KH curve types mainly. Also sites along the river road have their fifth and sixth layers consisting of medium to coarse grain and gravely sand which is indicative of high water bearing media (aquifer) within 30 - 25 m while sites around the quarry consist of rocks that are far depth with no distinct aquifer. Moreover, while most sites along Orin-Oyih river road have formations of relatively high resistivities, the formations of sites very close to the river and around the quarry exhibit low resistivities.
