【 摘 要 】

Vertical electrical sounding data were acquired from 12 locations evenly distributed around Obiaruku town and her environs. This is an attempt to obtain useful information on the aquifer distribution within the area and hence delineate possible depths boreholes could be drilled for portable and sustainable water supply. Based on the geoelectric section which is in agreement with the driller’s log, two near surface aquifers have been identified. The first aquifer consist fine-grained sand formation at a depth between 10.00 – 30.00 m and thickness between 10.00 and 25.00 m. The second aquifer consist medium-grained sand formation and occurs at a depth, between 20.00 – 45.00 m. The study revealed Obiaruku town and her environs as an extensive sandy unit; hence, the aquifer is not confined. Prospective groundwater exploration is therefore recommended in the second aquifer at a depth, between 20.00 – 45.00 m to enhance sustainable and portable water supply in Obiaruku town and her environs.
