dc.description.abstractThe impact of municipal and industrial waste discharges into Asa river in Ilorin, Kwara State, Nigeri was investigated. Section of the river along its course within the metropolis were studied by collecting water samples from five different points; Asa Dam, Unity Bridge, Station Bridge, Amilengbe Bridge and Kangile Village. Sample analyses were carried out at monthly interval (April 2008 to March 2009) for a period of twelve months covering both the rainy and dry seasons. Concentrations of ammonia-nitrogen (NH3 - N), carbon dioxide (CO2), dissolved oxygen (DO) and biochemical oxygen demand (BOD5) were determined at each sampling point as measure of organic pollution in the river. The results indicate that the quality of Asa river water was acceptable before entering and after leaving the town but pollution sets in as the river flows through the town indication that the river receives significant inputs of wastes from both domestic and industrial sources. Also, the level of pollution was found to be season dependent. Key: Pollution, river, waste, domestic, industrialen_US
