Abstract

Purpose This paper aims to examine the quality of the surface waters of the bitumen deposit area of Nigeria and also to establish the relationship between the deposit and the waters.Designmethodologyapproach Physicochemical parameters were measured using standard analytical procedures, while the elemental contents were determined using total reflection Xray fluorescence spectroscopy. Data acquired were interpreted using statistical techniques charts, ttest, pollution index PI and crossplot analysis.Findings A river located close to the bitumen well contained the highest concentrations of metals that are known to be associated with hydrocarbon formation. Comparison of the levels of the analyzed parameters in the waters with their standard permissible limits showed that the levels of Cl, SO42, total alkalinity and Cr, Mn, Fe, Ni, Cu, Zn and Pb in the river very close to the capped bitumen well and big rivers were high and low in the small streams. This was corroborated by their pollution index values.
