Abstract : The back water of river Potpoto is a prime source of water for Kanke Dam, located in Kanke of Ranchi district, have been studied to project the characteristics of water with respect to different pollution sensitive parameters i.e. organic pollutants- BOD, DO, COD, Inorganic pollutants – Electrical Conductivity, Turbidity, pH, total alkalinity, Chloride, Total hardness etc. The pH (7.68), total alkalinity (180.5 mg/l), Chloride (133.12 mg/l), Total hardness(139.83 mg/l), Calcium (60.26 mg/l) and Magnesium hardness (19.38 mg/l) were found well within the prescribed standard for drinking water (BIS10500:1991) during the study period i.e. December 2017- January 2020. The study inferred that the water quality of Kanke Dam is still free from the any kind of pollutants, must be due to its higher assimilative capacity. It also indicates the higher potential for pisciculture and drinking water sources (after disinfection) for the nearby villages which may ultimately improve the economic condition of the surrounding habitation.
