Groundwater investigations: experiences in parts of South Eastern Nigeria

Abstract

comAbstractTo serve as the basis for a preliminary estimate of aquifer potential in an area where there has been no successful water borehole, Vertical Electrical Soundings (VES) were carried out in conjunction with hydrogeological study in Okija. The study area is on the Ameki Formation. The interpretation of the resistivity sounding data indicates a depth of 59-81m to the aquifer. Interpretation of the field curves outlines the resistivity values (8955-9964 Ù-m) and the depths (59-81m) to the sand (aquifer) of thicknesses (65-73m) within the silt/sand intercalation of the Ameki Formation. The results also indicate generally the types and thickness of soil materials above the aquifer.

Keywords:Aquifer potential, vertical electrical soundings, Ameki formation, Okija.
