dc.description.abstractThe type of method adopted for this research was the 1D electrical resistivity, using the GEOPULSE SAS 300. A Schlumberger configuration was carried out to map the Geological feature of the earth subsurface. Five profiles were carried out in the study area. The layout geometry for the electrical resistivity was symmetrical Schlumberger arrays. The maximum current electrode separation (AB) was 140m, that is, AB/2=70m. The data obtained using Geopulse resistivity Meter SAS 300 were processed using computer software (IPI2Win). 30 vertical electrical soundings have been carried out that is each profile consists of six(6) vertical electrical soundings. Based on the electrical resistivity value obtained in the study area, the following deductions were made. The average depth to the fresh basement is about 29.8m. The study area has revealed the presence of two distinct layers, the top soil and weathered basement; the top soil is composed of laterite and brownish clay sand with an average thickness of 2.9m with resistivity ranges of 20-557 ohm-m. The weathered basement underlies the top soil with an average thickness of 26.6m; resistivity ranges between 100-978ohm-m and composed of laterite and clay. This (the weathered and top soil) layers constitute the overburden with an average thickness of 29.5m revealed by the geoelectric section. This weathered basement is a good aquifer in the study area. The depth of probing which is 29.8m is above the depth to the fresh basementen_US
