ABSTRACT
2D electrical resistivity using Wenner configuration was carried out in Kurfi Fadama of Sokoto State Nigeria. The study area lies
between latitudes 13°03ʹ13ʺN and 13°08ʹ21.47ʺN and longitudes 5°06ʹ36ʺ E and 5°17ʹ25.31ʺE with an estimated area of 9.0 km2
.
Six profiles were covered with each length 200m and spaced 50m apart using imaging technique which involves the use of Ohmega
resistivity meter and its accessories. The acquired data were analyzed, processed and interpreted using RES2DINV64 and SURFER
version 13 which instinctual gave an interpretation of the measured apparent resistivity data. The result from the data interpretation
revealed concealed features of the area such as lithological boundaries and water bearing formations. These characterized the area
as having five lithologies namely, Clay, sandy-silt, alluvial sand, shale/sandstone and clay/limestone/gravel. The identified regions
of P1, P2, P3, P4, P5 and P6 having lowed resistivity values ranging from 0 to 50Ωm were classified as saline due to clay layer has
the potential for water retention (aquiclude) and water accumulations (aquifer) that maybe as a result of excess application of
fertilizers and water lodging. These regions of lowed resistivities may impact the environment and Agricultural practices that
commonly apparent the crop productivity. However, high resistivity zones (700Ωm and above) were also identified as gravels
which usually has the highest tendency of water accumulation due to high porosity and permeability.
