abstract
Water samples were collected from three sites namely Nimtala Ghat, Jelepara and Banshtala Ghat of Kalnagini Creek at Kakdwip, West Bengal for six months (January to June, 2019). The pH, conductivity, TDS, salinity, temperature, and turbidity were measured using deluxe water analysis kit. Dissolved oxygen, alkalinity, and free CO2 were estimated using standard method. The analysis of physico-chemical characterization of water of the Kalnagini creek demonstrated that during the monsoon season (May to June) the water quality was deteriorated leading to the great concern of that particular area. Water quality of the Kalnagini creek was better in winter season (January & February, 2019). The result showed availability of highest dissolved oxygen during winter season due to its low water temperature.
