Abstract

Petroleum operations are potential sources of environmental pollution capable of contaminating rivers which pass through the industrial areas and consequently affect human health. Hence there is need for bioremediation interventions. The aim of this study was to provide data on the physical and chemical characteristics of surface water and effluent in the study area which could be used for bioremediation strategy in the area. Surface water and effluent samples were analysed for physicochemical parameters using standard methods. The surface water and effluent were acidic. Temperature was found to be within the range favourable for bioremediation.                The dissolved oxygen (DO) is not limiting for bioremediation. Electrical conductivity and chloride were high. Low levels of nitrate nitrogen (0.30 – 2.42mg/L) observed are limiting for bioremediation. The effluent and Romi River downstream had BOD greater than the allowable limit (10mg/L). Biostimulation is recommended as bioremediation strategy in the site.
