Assessment of Water Quality of River Salandi by using Modified Canadian Council of Ministers of the Environmental Water Quality Index Method in Bhadrak, Odisha, India


By utilising the Modified Canadian Council of Ministers of the Environment Water Quality Index Method in Bhadrak, Odisha, India, the current study highlights the water quality of the River Salandi. In order to fulfil the purpose and goal of this investigation, nine sampling stations were chosen along the river’s bank on the basis of the presence of more anticipated pollutants. In order to evaluate the sixteen physico-chemical parameters, water samples from nine different locations during the summer, wet, post-rainy, and winter seasons of the years 2015 and 2016 were analysed. APHA-2012, from which the mean and standard deviations (SD) of twelve parameters have been computed and derived to investigate the Water Quality Index (WQI) using a modified version of the Canadian Council of Ministers of Environment (CCME) approach for the years 2015 and 2016. According to the report, the water quality in both years is just fair and falls into class-D. Additionally, it is determined that the larger amplitude is the cause of the relatively lower water quality in 2016 compared to 2015 (F3). In addition, study of physico-chemical characteristics shows that the river Salandi is contaminated with harmful bacteria, Cr(VI), iron, chloride, and fluoride, with the severity of the pollution being greater during wet seasons. post-rainy than the summer and winter seasons and pollution follows a decreasing trend from upstream to downstream. In addition to using contemporary techniques like electrodialysis, disinfection, and reduction of Cr (VI) with SO2 in acidic medium followed by lime treatment to turn Cr (VI) into Cr(III) as chromium hydroxide, along with phytoremediation and bioremediation for the treatment of toxic substances and pathogenic bacteria, and concurrently increasing DO value through photosynthesis.
