WATER QUALITY ASSESSMENT OF DALVOY LAKE WATER, MYSORE, KARNATAKA, INDIA (original) (raw)

Healthy lakes indicate healthy and eco friendly life style of the people in its neighbourhood. Lakes play a pivotal role in maintaining the ecological balance. Lake water is generally used for drinking, domestic and irrigation purposes. Therefore, it should be free from the pollutants and Dalvoy Lake water is no exception as it is life line for the people of nearby four villages around it. Although, the lake is situated at the outskirts of the city of Mysore, but its water is getting mixed with urban runoff, underground drainage and sewage water from the city. This made authors curious to study its Water Quality Index (WQI) with an objective to assess the quality of water for human consumption. Thus the water quality parameters like Mg 2+ and C 2+ ions, pH, Total alkalinity, Total Dissolved Solids, Electrical Conductivity, hardness, etc of the lake water were studied using standard methods and WQI was calculated on the basis of Weighted Arithmetic Index.
