ASSESSMENT OF DRINKING WATER QUALITY OF BHAVANIRIVER IN TAMIL NADU, INDIAK. Ramah, R. Premchand, K. Sivakumar and M. TilakAbstract Fresh water bodies, particularly rivers are getting polluted, thus decreasing the potability of water. A primaryreason for this is that all three major sources of pollution viz., industry, agriculture and domestic, which areconcentrated along the rivers. A study conducted to assess the physico-chemical properties of the Bhavaniriver water at three locations viz., Avalanche, Mettupalayam and Kooduthurai revealed that two parametersviz., dissolved oxygen and chemical oxygen demand at Mettupalayam and five parameters viz., EC, totaldissolved solids, dissolved oxygen, biochemical oxygen demand and chemical oxygen demand atKooduthurai were beyond desirable limit. In these locations, water has to be treated with treatments suchas distillation, reverse osmosis and deionization to make it potable. The river is highly polluted due todischarge of domestic and industrial waste particularly dyeing, textile industries through several drains. |
