ABSTRACT
This study characterized aquifer and
assessed dump sites in Ikot Ekpene, South East Nigeria, located between latitudes 5010’N
and 5014’N and longitudes 7040’E and 7045’E.
The study delineated the groundwater potential of the study area using
geophysical techniques. The survey procedure adopted for field data acquisition
is the Vertical Electrical Sounding (VES) and the Electrical Resistivity
Tomography (ERT) imaging with the aid of a signal stacking resistivity meter (SSR-MP-ATS).
The Schlumberger configuration was used to acquire VES data at nine (9) points
and 3 sets of ERT images were obtained using Wenner configuration. The VES results show that the topsoil had resistivity values
ranging from 22.5
to 51.3Ωm and
layer thickness that also range from 0.6
to 1.3m. The range of the resistivity of the second
and third layer is 11.3 to 1001.8Ωm with a thickness of 0.6 to 8.2m. The third
to fifth geoelectric layers were delineated. The last layer in the VES
indicates sand of resistivity between 725.6 - 2408.7Ωm. It was concluded that
an elongated leachate contaminant from the dump sites may constitute future
environmental threats.
