Humans now strongly influence every major aquatic ecosystem by their unpleasant activities which has resulted in alterations in the normal characteristics and the self-purification ability of water. The excess load of nutrients into the water bodies has resulted in various adverse effects of which eutrophication remains the most prominent of all. It has even lead to various diseases in human beings as the freshwater ecosystems are also getting affected by the wrath of eutrophication. People consume the water and infected organisms of those water bodies which results in various dreadful diseases. This report examines the water quality parameters of 2 of the most prominent water bodies of the capital city of Jharkhand, namely The Ranchi Lake and The Kanke Dam. Study of the physico-chemical characteristics of these water bodies were done for a certain period of time from November 2018 to March 2019. The parameters discussed in this report are – pH, Conductivity, Total Dissolved Solids (TDS), Dissolved Oxygen and Biochemical Oxygen Demand (BOD). The analysis of the parameters done in this report are the most recent ones. Most of the parameters were not found in the desirable range for drinking water and hence appropriate measures were suggested to improve the water quality. Eutrophication causes a tremendous increase in the algal growth on the surface of the water body, which has been reported world-wide, especially for freshwater ecosystems. The excessive algal growth does not allow photosynthesis to take place properly and thus a Hypoxic zone gets created underneath the mat which proves to be lethal for the aquatic community. This report also contains a brief description of the types of eutrophication, the factors getting disturbed due to eutrophication and the management and control measures to be taken for controlling the adverse impacts of eutrophication.
