ABSTRACT
The
study was carried out to investigate the aquifer potentials and subsurface
lithology in Akwa Ibom State Polytechnic Campus Ikot Osurua. The Study area
lies between latitude 5ᴼ091
and 5ᴼ401N and longitude 7ᴼ181 and 7º201E. It is underlaid by
sedimentary formation of late tertiary and holocence ages. A total of twelve
(12) vertical electrical soundings (VES) were conducted using the integrated
Geo-instrument Service (IGIS) resistivity meter to generate the field data. The
schlumberger sounding was carried out with current electrode spacing (AB)
ranging from 1-300 m. The distance used for the potential electrode spacing
(MN) ranged from 0.25 -10 m. The field data obtained were subjected to
interpretation by partial curve marching and then by computer iteration using
IP12WIN software. The interpreted results were constrained by lithologic log to
produce the geo-electric sections of the subsurface. The geoelectric section
showed three(3) to five (5) layered subsurface
of top soil, Lateritic sand,
Consolidated Sand, Clay sand and aquifer layer with different curve types which
were Q, KA, K, KK and HQ. Aquifer characterization of the area showed the
aquifer resistivity and depths ranging from 30.6 to 6489 Ωm and 50 to 100 m respectively
although it varies in some location, this is an indication of the presence of
fresh groundwater.
