Abstract: Integrated geophysical and geochemical investigation was helpful in mapping areas of contamination in subsurface formation. Electrical resistivity surveys were carried out at a site of shallow hydrocarbon contamination and were correlated with geochemical analysis in Ikarama, aimed at investigation contamination plume of the subsoil. Thus, three (3) Electrical profiling were carried out using ABEM SAS 1000 terrameter, and six (6) subsoil samples were collected from the study area; which was analyzed using the Atomic Absorption Spectroscope (AAS) and UV Spectrophotometer and the analyzed result was compared with the World Health Organization Standard. The result revealed high contamination content of lead (Pb) at profile 1, 18 mg/l and profile 2, 8.1302 mg/l, while Mn was 6.6611mg/l and 7.7778mg/l at profile 1 and profile 2 respectively. While for the TPH, we have high (404 mg/l) and (124 mg/l) contamination concentration at profile 1 and profile 2 respectively; both at the unsafe zone and low (25.8mg/l) at profile 3, known as the control zone. The very high contamination concentration values for all subsoil samples which exceeded the WHO permissible standard indicates that aquifer may likely be polluted by intrusion. It is advisable to carry out proper water treatment from source and soil degradation, for potable drinking water and cultivation of agricultural product respectively for social economic development.
