Abstract
The present study was done to assess the water quality of river Kalyani in context of its pollutants load. Water samples were collected from five sampling locations of the river and analysed for physico-chemical water quality parameters such as pH, EC, TDS, BOD, COD, Sodium and Chloride. Among the five sampling locations, Jagatpura and Dhobhighat i.e. 230 mg/l, 1010 mg/l and 260 mg/l, 1012 mg/l respectively. The Sodium and Chloride concentration were also high in location Jagatpura and Dhobhighat i.e. 110 mg/l, 738 mg/l and 114 mg/l, 741 mg/l respectively. These results indicated these locations are the most polluted because of the discharge of domestic waste and untreated or partial treated industrial effluent. The WQI was calculated for all the locations and the results estimated that location Pattharchatta has moderate water quality, location River Crest has poor water quality, and location Jagatpura, Dhobhighat and Khanpur has unsuitable for drinking water quality .Rivers are remain an important source of drinking water for many towns and cities, so it is necessary to protect river system and from pollution. Hence WQI is the best tool to determine water quality status and provides data that can be simply understood by the community. Thus, it facilitates the water management system that need to be implemented to improve the water quality on the basis of its water quality status.
