The presence of Polycyclic Aromatic Hydrocarbons (PAHs) in territorial water is of great concern due to the carcinogenicity. In this study, monthly collection of surface water from four artisanal petroleum marketing points was made from November 2019 - October 2020 using standard methods. Hydrocarbon utilizing (Hydrocarbonoclastic) bacteria were isolated by vapour phase transfer method using mineral salts medium, isolates were identified based on cultural, morphological and biochemical characteristics. The mean HUB count was 1.2 x 104 cfuml-1. The HUB isolates were Pseudomonas, 12.4%; Chromobacterium, 1.8%; Serratia, 5.3%; Corynebacterium, 6.25%; Escherichia, 12.1%; Bacillus, 12.4%; Staphylococcus, 10.6%; Micrococcus, 3.5%; Citrobacter, 7.1%; Enterobacter, 3.5%; Acinetobacter, 3.5%; Alcaligens, 4.4%; Nocardia, 3.5%; Streptococcus, 6.2%; and Shigella. 6.2%. The PAHs level in the surface water samples were determined used Gas Chromatography - Flame Ionization Detector, GC-FID. The PAHs level observed was a mean of 0.004mgl-1 which is below the EU permissible limit of 0.007mgl-1; which can be attributed to activities of the polycyclic aromatic hydrocarbon mineralizing bacteria present as a natural consortium in the ecosystem. If the presence of these strains of bacteria continues in the ecosystem, the continual stability of the ecosystem can be ensured. This study reveals a natural bacterial consortium that can degrade PAH in the surface water within a short time.
