Understanding the water quality for drinking and agricultural uses is important. The main sources for the water contamination in the rivers are industries, agriculture and domestic sources. Most of the industries and cities are located along the river basin which is a convenient place to discharge waste materials. Chemical waste products from the industries, like paper mills, leather industries and dyeing industries sometimes accidentally discharge harmful chemicals into rivers in high concentrations that affect all living beings. In order to assess the water quality in the Cauvery river, samples were collected and analyzed for turbidity, pH, chloride, total hardness, total dissolved solids, chemical oxygen demand, dissolved oxygen, biochemical oxygen demand, etc. Qualitative ratings classified the river waterfalls into the category very poor according to the water quality index. The water quality ranges from 112.27-348.5. The overall quality of the waterfalls under the very poor category. The Cauvery river water gets polluted by the discharge of untreated wastewater from the industrial sectors.
