Geoelectric and Hydroelectric Parameters of Aquifers in Southern Parts of Akwa Ibom State

A Vertical Electrical resistivity Sounding (VES) survey was carried out, to study the geoelectric and hydroelectric parameters of aquifer in some locations in Part of Akwa Ibom State. A total of six (6) geoelectric soundings were acquired. The lithology of the aquifer layer can be said to compose of fine to gravelly sand, with sand and clay intercalation. The low resistivity values across most of the geoelectric layers can be attributed to conductive argillaceous geomaterials. Underlying aquiferous layer is likely unprotected from the surface contamination flow due to the fact that the protective capacity of most part of the study area is good as shown by this study. Contour maps generated using the results from the study shows bulk aquifer resistivity and water resistivity values, the formation factor calculated ranges from 2.3-50.45. Porosity ranges from 8.68-48.27% and hydraulic conductivity ranges from 0.671 m/day 2 from estimates. Porosity values obtained confirms that aquifer in the study area consist mainly of sandstone. It is also revealed that, areas with low resistivity have high porosity and the storativity as observed in the extreme south and central parts of the study area.
