Abstract: The study aims at to compare the water quality of lakes of Bangalore and Hyderabad cities. Balladur Lake and Osmansgar Lake were selected from Bangalore, Karnataka and Hyderabad, Telangana state respectively. The secondary data of water quality of the lakes was collected and analyzed. pH, Turbidity, Total Alkalinity, TDS, Calcium, Magnesium, Chloride, Sulphates, Nitrates, DO, BOD, COD were taken to study. The result of both Lakes polluted and it could be due to many activities such as saltation, infringement and eutrophication. Development of human population in last century was witnessed a comparable extension of city and urban lakes were converted as sinks for pollutants. Dense population was observed in metropolitan cities like Bangalore, Hyderabad, Mumbai etc. The effect of developed urban areas is the main factor degradation and loss of lakes in Bangalore and as result, in the city only 17 good lakes exist as against of 51 healthy lakes in 1985.Where as in Hyderabad, most of urban lakes were artificially created to cater to the domestic and irrigation needs. Later increased in human density, city culture demands and industrial growth effect significantly on the catchment areas and many were disappeared. Therefore, proper treatment and conservation strategies are to be adopted before discharge. Keywords: Bellandur Lake, Osmansagar Lake, Water Quality, Physico-chemical parameters, Comparison of Lakes.
I. INTRODUCTION Water is an essentialcomponent in designingof land and controlling of climate as well as that can affect on life. Further, it is regarded as important role in sustenance of life on the earth. Live is not possible without water. About 2/3 mass of our body is water and 70 % surface of the earth covered by water. Where above 95% of water presence in gigantic oceans. About 0.00015% is exist in rivers and lakes have 0.01% of water on the earth. in 21 st century one of the problems is supply of safe water and safe water-supplies and environmental cleanliness which are vigorous for protection of environment, improving health safety and decreasing indigence. As per World Water Assessment Programme published by UN, the available water per person is decrease up to one-third over next 20 years and so about 2.7 billion people will have experience of acute water scarcity by 2025. And arrival for clean and closer drinking water is still a remote dream for about one-sixth of human in this planet (Harvey, et al, 2002 and Smedley and Kinniburgh, 2002).The prophesy has shown that this increase in scarcity of water, and conteston water in first half of 21st century, may change the importance and use of water (Mroczek, 2005).Water is mainly provided by the rivers, lakes, ponds, ground water, rain water etc.Where the rivers, lakes, ponds. Streams, oceans and other surface water bodies are work as rich aquatic ecosystem on the earth and contain various physico-chemical and biological parameters which are having interaction with each other to sustain the ecosystem. Surface water bodies not only have the value of providing habitat or ecosystem for living organisms, they are also after proper treatment used as a source of drinking water in most of the regions.
