Lithological Examination and Resistivity Trend Pattern Investigation of Groundwater Research in Philipa Idogho Campus Auchi Polytechnic, Auchi

Abstract

The ground water research venturing is very vital for creating and providing artificial surface water availability based on the scientific method of drilling. The paper examined the empirical trend analysis of VES (Vertical Electrical Sounding) of Auchi Polytechnic Ground Water Project 2011 to establish the variation and existence in the ground water, based on lithology, resistivity and the chemical components present. The pattern of the VES resistivity showed that the apparent resistivity value for the saturated layers is fairly low indicating good aquifers. In addition, a suitable drilling rig that can effectively drill to the required specifications and depth should be mobilized to the site for the project. The entire (On-the-site) drilling process should be supervised and documented by a competent and professional geologist and/or hydro-geologist who should also determine the final and terminal depth of the borehole at the site. Total drilled depth of 197m (650ft) is recommended.
