Current Status of Pollution in Sagar Lake Using Geoinformatics

Water Pollution is the presence of harmful and objectionable material in water to make it unfit for use. In recent time, quantity of fresh water is reducing day by day and there has been increasing awareness and concern about water pollution all over the world and new approaches towards achieving sustainable water resources have been developed globally. In general, problems affecting water quality and aquatic ecosystems are untreated domestic sewage, uncontrolled industrial discharges, deforestation and poor agricultural practices that result in soil erosion and leaching of excess nutrients and pesticides, ultimately polluting the water sources that we drink from. Similar is the case in the Sagar Lake, here the waste-water from all around is polluting the water day by day. In the past, it was fresh water natural lake but now it has been polluted. In order to understand the current status of pollution, author(s) have attempted to compare the result of chemical analysis spreads of pollutants in lake water observed on satellite images and finally identified four major spots. Further, spots on the basis of these studies planning can be made to abate this serious problem.
