Abstract:
A geophysical investigation of the earth's interior involves taking measurements at or near the earth's surface that are influenced by internal distribution of its properties whose measurements can reveal how the physical properties of the earth's interior which may vary vertically in the sub- surface. The observations at Ode-Remo, a town in Remo North Local Government Authority in Ogun State that water needs in the area is becoming unbearable despite the increasing population of the town hence prompted the study to examine the quantity and quality of the ground water. Ground water is protected from surface pollutants as the earth's media composing of different sub-surface layers act as natural filter to infiltrate water. The geophysical investigation involved carrying out Vertical Electrical Sounding (VES) techniques applying Schlumberger configuration on the locations. Data collected were analysed using both Quantitative and Qualitative interpretation to produce the geoelectric sections. The analysed data revealed that p1< p2 < p3 < p4< p5< p6 with the topsoil comprising of clay/sand/laterite, sandy clay, clayey sand, coarse sand and hardpan. The information reveals that the subsurface is representing a typical example of a sedimentary environment and the aquifer units.
