Abstract
Water bodies are the natural resources that behave as groundwater rechargers, flood disaster prevention agents, and economic resources for piscators. Urban surface water bodies in the currently prevailing situation act as drain storage, pollution barriers, and encroachments on built-up areas. This study provides the water quality of water bodies in map view using open source data published by the Telangana Pollution Control Board (TSPCB). Water quality parameters are classified on the basis of the categorization provided by the Central Pollution Control Board (CPCB), India.. Study area Hyderabad is well known as the City of Pearls and Lakes, as it owns numerous water bodies that once served as drinking, cultivation, and flood disaster preventers. Hyderabad city is enlarging its population and spatial extent, but its drinking water source is still dependent on two lakes, the longest distance, and three high-elevated rivers. Once, it had thousands of lakes, which now shrink to 185, out of which no lake is permitted as a drinking water source. The present study focuses on the water quality mapping of the study area to show how the water bodies are polluted. Toposheets from the 1970 Survey of India were used as a base map to delineate full tank levels. The two hundred and thirty-one water bodies were digitised using various temporal toposheets and the TSPCB, which provided one hundred and eighty-five lakes with water quality data. The result shows the huge impact on health diversity of the study area, as no water bodies are used as drinking water sources and only thirteen water bodies are used for outdoor bathing. Only eight water bodies were used as drinking water sources after conventional treatment. Other water bodies are classified as disappearing, dried, and other classes.
