Assessing Water Quality of Kala Talao by Adopting Pollution Remedies

Now a days conservation of natural and artificial sources of water is of great importance due to water shortage. Natural and artificial lakes are important sources for ground water recharging. It is therefore absolutely necessary to conserve lakes for betterment of sustainable development. This project concerns with the study of water quality of Kala Talao, Kalyan. Kala Talao is located in the Kalyan city and has its sides lined throughout with broken basalt masonry. The physico -chemical study of the water body is being conducted to assess the present status of water quality and to suggest the conservation strategies based on the findings. The parameters taken to calculate Trophic State Index (TSI) are Temperature, Secchi depth, pH, Suspended Solids (SS), Dissolved Oxygen (DO), Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), Total Phosphate, Nitrate Nitrogen, Chlorophyll-a, M. P. N. In present study, Trophic State Index is calculated for the June 2014 to May 2015 comprising of three seasons, summer, winter and rainy season. The Trophic State Index (TSI) calculations can be useful in conservation of Lakes. Trophic State Index (TSI) for Kala Talao has been calculated for September 2014 and February 2015 and May 2015 is 85, 75 and 53.96 respectively. This proves that Kala Talao was in Hyper-Eutrophy stage (as value is greater than70) in rainy season. Physical and chemical parameters of the Kala Talao water are analyzed after completion constructive work for pollution prevention in May 2015.
