Abstract

Summary

An investigation of the contaminants of the environment especially groundwater with hydrocarbon leakages from pipelines has remained a major concern globally. The purposes of this study were to map the extent, analyzed the chemical composition of the plumes, and estimate the water quality index of the water samples collected in the study area using geophysical and physicochemical methods. Six traverses were occupied and a total of thirty VES data were collected. The sixth traverse was designated a “control” traverse. Some water samples from hand dug wells and boreholes were collected. For this study, four to five geoelectric layers were delineated indicating topsoil, contaminated sand, sandy clay/clayey sand, sand and clay. The physico-chemical analysis revealed that BH-1 to BH-7 have anomalously high BOD, TDS,and conductivity above the acceptable level. At present, the groundwater in the area is not potable; therefore, concerned agencies or government should embark on remediation to salvage the groundwater aquifer system in the area from a total damage. The electrical responses from the resistivity measurements using both vertical electrical soundings(VES) and 2D electrical profiling were good at imaging the contaminated zones. For this study, the electrical techniques reveals that relatively high resistivity associated with the supposed contaminated zone.
