This paper describes the uater quality of Niluala Ganga river in Southern Sri Lanka in terms of variations of the following parameters with seasons and length of river: Acidity, Chloride, Ammonia, Nitrite, Biological Oxygen Demand, Dissolved Oxygen, and Conductivity. The influence of rainy season and agricultural activity in the catchment area of Niluala is clearly demonstrated. The need for systematic monitoring and waste water treatment of waters of tropical rivers is evident, in particular where impacts from industrial-agricultural projects are to be expected.
