Description
Urbanization is speedily catching on erstwhile fallow hinterland area of southwest Nigeria. Due to the various
production companies springing up in the location adjoining area are experiencing influx of citizenry and
accommodation and sustenance become a predominant challenge. Portable water is critical to the survival of
man, hence the reason for this study. Electrical resistivity survey were carried out at Jubilee Homes Parkland, to
delineate subsurface layers and determine the ground water potential, so as to make adequate provision of
portable water supply for the settlements springing up within this area. The electrical resistivity method adopted
for this study employed the use of ABEM SAS 1000 terrameter which worked on 16 vertical electrical sounding
(VES) points within the area. A maximum distance of 550m current electrode (AB) spread was adopted for this
purpose. The result shows the presence of four geoelectric layers with the resistivity of the first layer ranging
from 25.54Ωm-619.45Ωm and thickness of 0.14-9.21m representing topsoil. The second geoelectric layer has a
resistivity ranging from 20.94Ωm-706.82Ωm and thickness of 2.58-35.36m representing laterite, while the third
geoelectric layer has a resistivity ranging from 12.29Ωm-598.93Ωm and thickness 3.33-58.06m representing
sandy clay. Finally, the fourth geoelectric layer has a resistivity ranging from 12.10Ωm-1980.52Ωm and
thickness of 11.4-45m representing sand. It can be concluded that the fourth layer is most prolific and attractive
to be explored for groundwater. This thereby affords residents and potential settlers in the area a considerable
confidence level in accessing sufficient groundwater for their various uses. Furthermore, construction purposes
ongoing in the location could make use of this evaluation to satisfy their need of locating water for their
operations
