Water Quality Index of Jalangi River in Nadia District of West Bengal
The river waters of Jalangi got polluted at its downstream stretch at Krishnanagar due to municipal waste discharge as well as mixing of industrial effluent from The Kishan Cooperative Milk Producer Union Ltd even 7-8 years back. Jalangi River water is currently useable for outdoor bathing after drastic sewage treatment by chlorination for disinfection of faecal coliform bacteria as well as using screen and sedimentation tank for the precipitation of different solids remained in the domestic sewage at the outlets of eight drains of Krishnanagar municipality.The water quality rating applying the formula of water quality index shows 60% good and 40% fair conditions of surface water of Jalangi River for the months from January to May 2020 which was almost poor during 2013-14 and 2014-15 respectively. Application of modified standard values for individual parameters for the computation of WQI reveals similarities of WQI values with the data of physicochemical parameters of river waters of Jalangi.
