DEDUCTION OF GROUNDWATER POTENTIAL FROM GEO-ELECTRIC DATA IN SARDAUNA MEMORIAL COLLEGE KADUNA, NORTH-WESTERN NIGERIA

Abstract

Vertical Electrical Sounding (VES) employing the Schlumberger Electrode configuration was used to provide 
information about the subsurface lithology with the aim of evaluating its groundwater potential through deductions 
from Geo-electric data.  A total of 25 VES points ware sounded along the five profiles with five sounding station per 
profile, covering a total area of about 10000M2. The VES data acquired were used to produce the VES curves, the 
coefficient of reflection and longitudinal conductance map. The VES curves were interpreted using ipi2win 
resistivity computer software and the iso-maps of the coefficient of reflection and longitudinal conductance ware 
produced using surfer11 software. The results of the investigation revealed that the survey area is dominated by a 
maximum of four layers, namely; top soil which is mainly dominated by lateritic soil, the weathered basement, the 
fractured basement and the fresh basement. The water bearing zone (aquifer) was captured within the fractured 
zones of the study area and the excellent locations were identified to be located at south-west zone of the study area 
because of the positive correlation between the two maps produced. This area was having a high promising potential 
for borehole citing
