ABSTRACT
The impact of brewery effluent on the water quality of Ikpoba river was investigated from March to May 2010. Physicochemical parameters of the sample stations were analyzed for compliance to the environmental protection agency (EPA) limit for industrial effluents discharge into water bodies. Total microbial colonies counts were determined for each station. Bacteria and Fungi isolated were identified and characterized. Nine bacteria genera were characterized and they include Vibro, Salmonella, Klebsiella, Staphylococcus, Bacillus, Pseudomonas, Escherichia, Proteus, Micrococcus. The fungal isolates include members of genera Aspergillus, Penicillium, Helminthosporium, Fusarium and Geotrichium. Comparison of the physico chemical properties showed higher mean values in station 1, 2 than station 3 and 4. Electrical conductivity, Colour, Total Dissolved Solids (TDS), Biological oxygen demand (BOD5) and exchangeable bases like carbonates and other anions were high at station 1, point of brewery effluents discharged into Ikpoba river. The brewery effluent negatively impacted on the water quality of the river, thus the need for the proper effluent treatment before disposal into the water bodies.
