【 摘 要 】

A study of 10 vertical electrical soundings from different quarters of Emu kingdom using Schlumberger array were undertaken. This is an attempt to obtain useful information on the aquifer distribution within the area and hence delineate possible site boreholes could be drilled for potable and sustainable water supply. Based on the geoelectric section which is in agreement with the driller’s log, the best environments for sustainable water supply were identified. This coincides with the third layer of the aquifer in Emu kingdom and consists of medium-grained sand formation. The average depth to this aquifer is 45 m whose thickness is not defined at Obiogo since it is the last layer, but in other parts of Emu-Kingdom, the thickness ranges from 45.00 m in Ikosa quarter to 95.00 m in Etevie quarter. The resistivities of these layers vary from 1000.00 - 3000.00 ohm-m. The aquifer system of Emu Kingdom has an overlying confining bed without an underlying confining layer, hence it is leaky or semi-confined. The thickness of this confining upper bed is greater at Ebendo and Obodoeti, hence in the event of pollution, groundwater at Obiogo, Ikosa and Etevie quarters in Emu-Uno are highly contaminated.
