520			_aWater quality of Bhagirathi-Hooghly River is measured by the West Bengal Pollution Control Board (WBPCB) and the river is one of the significant drinking water sources for Kolkata Metropolitan Area (KMA). This paper made an attempt to investigate water quality of the river. Water quality data Collected from WBPCB for 2015-16 and 2018-19 across eight monitoring stations and analyzed in this study. Study reveals that pollutant loads from urban local bodies have shown stronger impact on the water environment. Water Quality Index (WQI) indicates that pollution of the Hooghly River increases during monsoon and post monsoon period while at summer it remains relatively low. BOD and total coliform count shows a strong correlation apart from pH and dissolved oxygen. The average pH of the river water ranges from 8 to 9 throughout the year. Total Dissolves Solids (TDS) and electrical conductivity also shows significant correlation. Principal Component Analysis (PCA) reveals that BOD, total coliform and turbidity varies together which is result of unregulated discharge of sewage water from urban local bodies (ULB) in the river.
