Industrialization has been expanding rapidly in Uganda particularly in Kampala City Council Authority. Nakawa and Ntinda happen to be among those areas with rapid industrial growth in this city. However, the environment in these industrial zones has not been given due attention with regard to its conservation and sustainability. The existing Kinawataka stream, its tributaries and Kinawataka swamp could be degraded with increasing industrial activity in this area. In this study, levels of heavy metals (zinc, copper, lead, cadmium and nickel), oil and grease, organic loads, oxidized nitrogen, total phosphorus and the physical properties of pH, conductivity and temperature were investigated in Kinawataka stream, its tributaries and Kinawataka swamp. Compared to background levels, results showed no significant quantities of heavy metals. The waste stabilization ponds in the area seemed to have high significant contributions to total phosphorus in the Kinawataka stream. It was concluded that the swamp exhibits an excellent character in moderating the hydrogen ions activity (acidity) of the streams, leading to no significant change in the mean pH values on the entire streams and this could have been due to the presence of the swamp.
