COMPARATIVE EVALUATION OF WATER BODIES OF RANCHI WITH REFERENCE TO ALGAL DIVERSITY

Four water bodies of Ranchi (Jharkhand) viz. Ranchi lake, Line tank, West Jail road tank, and Hatania tank have been studied with a view to monitor for physico-chemical status on the monthly basis for one year. These water bodies receive mainly domestic and municipal wastes and are situated in the populated areas. Algal flora have been identified and prevalence of species diversity of characteristic algal flora is understood in relation to physico-chemical parameters. Water Quality Index is obtained in response to certain important physic-chemical factors. These analyses provided converging lines of evidences for assessment of pollution.
This has been reemphasized that biologists and planners must make serious attempts to revitalize fresh water bodies to become more usable in order to withstand the ever rising population load.
