Evaluation of Physicochemical and Biological Parameters on the Water Quality of ShilabatiRiver, West Bengal, India

Anthropogenic activities affect the rivers and entire basin in different dimensions. All river basins including Ganga Damodar are polluted from unplanned anthropogenic activities. This study is an attempt to access quality of Shilabati River by computing water pollution index using eleven parameters pH, COD, BOD, DO, TDS, Total Hardness, Alkalinity, Phosphate, Chloride, Nitrate, Turbidity measured at eighteen sites. The BOD TC counts found be 2.45 mg/l 9334 MPN/100 ml; which reveal that falls under moderately category Central Pollution Control Board. high phosphate concentration suggests a heavy load industrial wastes contributes rise COD BOD. concentrations also account for eutrophic water. physicochemical fall mostly E Water Quality Index, Comprehensive Eutrophication values show poor seriously indicating not suitable drinking, domestic purpose, healthy survival aquatic life needs urgent management.
