Apparently, the above mentioned challenges of Awka and environs have proven the basis to unleash the aquiferous zones and parameters from the analysis of groundwater system for proper knowledge of aquifers in the study area. The use of electrical resistivity method which is the most commonly used geophysical method of groundwater exploration were employed in this study. In this electrical resistivity method, the use of Schlumberger array posed greater importance in delineating the aquifer parameters described by depth, thickness, transmissivity and hydraulic conductivity. Aquifer is described as geological formation capable of yielding economic quantity of water through recharge and discharge via water cycle. VES data of the nine (9) communities of Awka and environs at two locations each were plotted with IPI2WIN software and interpreted geologically and geophysically in subsections, the results revealed 4-6 layers. The nine (9) communities of Awka and environs were subdivided into zone A and zone B to enable easy work flow and pumping test analysis using the two existing borehole VES 4 and VES 14 data.
