The present study was conducted for a period of one year i.e., from March 2015 to February 2016 to assess the impact of Serlui-B Hydel Project on the water quality of Serlui river, as river water is directly used for drinking and various other domestic purposes by the local people settled in vicinity. Altogether, three sampling sites were selected for detailed investigation along the river from upstream to downstream along the hydel project. The water samples were collected at monthly interval for analysis of various parameters namely, Temperature (22.2˚C-34.3˚C), pH (6.1-7.7), Electrical Conductivity (81µS-154µS), -1 -1 -1 Dissolved Oxygen (5.7-8.1mgL ), Biological Oxygen Demand (0.6-2.2mgL ), Acidity (31-68 mgL CaCO3), Total Alkalinity -1 -1 -1 -1 (18-70mgL CaCO3), Chloride (21-145.67mgL CaCO3), Phosphate-P (0.017-0.210mgL ) and Nitrate-N (0.14-0.60mgL ).
