Oil will form a thin film on the surface of the water. Some oil which are volatile will give rise to odors and hence will reduce the aesthetic value of the river (Aesthetic issues). The presence of oil layer on the surface will cause some aquatic organisms to die because they cannot get adequate amount of oxygen. Detergents in river water can cause huge problems to aquatic organisms. Detergents can destroy mucus layers that protect fish from bacteria and parasites, and can damage the gills of the fish (Detergents occurring in freshwater, n.d.). Detergents also will reduce the breeding ability of the aquatic organisms in the river. Besides, detergents will reduce surface tension of water and increases the probability of organic chemicals to be absorbed by the aquatic organisms (Detergents occurring in freshwater,
