Chemical, biological assessment and water quality index of Lower Manair Dam

Author(s): L. Srinivas, Y.Seeta, P.Manikya Reddy
Abstract: The present study was carried out to assess the quality of water in the Lower Manair Dam, Karimnagar district. To study the quality of water by evaluating physico-chemical parameters, biological parameters and water quality index for a period of two years. It is the main source of drinking water for Karimnagar, surrounding villages, Warangal, agriculture and supports fish culture. The surface water samples were collected and analysed various physico-chemical parameters. All the physico-chemical parameters were well below the permissible limits. Mainly four groups of planktonic algae were recorded in Lower Manair Dam. They were Bacillariophyceae, Chlorophyceae, Cyanophyceae and Euglenophyceae. Bacillariophyceae dominating during the entire study period. The water quality index (WQI) values of the study area were calculated. pH, total alkalinity, chlorides, total hardness, calcium, magnesium, nitrates, sulphates, total dissolved solids and dissolved oxygen were the parameters considered for the calculation of Water quality index. The water quality index levels of the lake and all the three stations were clearly shows that, the status of the water body is oligotrophic and it is suitable for the human consumption.
