Abstract

The rivers of Bangladesh have a vital role as a valuable natural resource that sustains an economy focused on agriculture. It is very important to make sure the water is safe for many uses, like drinking, cooking, growing, and keeping marine life alive. The rivers Moyur, Bhairab, and Rupsha are very important to the people who live in Khulna City. The water bodies are getting worse because of things like fertilizers, oil, garbage that hasn't been cleaned, and industry waste. For ten months, from August 2022 to May 2023, researchers kept an eye on how polluted the river was. Every month, 18 samples of water were taken from six different places in the three rivers. Each sample was taken one foot below the water's surface. The data showed that during the rainy season, the BOD, TDS, salt, DO, and pH levels in the Bhairab and Rupsha rivers stayed the same. But according to the rules set by ECR (1997) and WHO (2004), the amounts of COD, chloride, total TSS, Total Dissolved Solids (TDS), and turbidity during the dry season were higher than what is good for people and aquatic environments. On the other hand, the Moyur River had chloride, pH, and TDS levels that were within permissible ranges. Problems regarding the water's health arose, however, because DO, BOD, COD, TSS, and turbidity concentrations continuously surpassed clean water limits during the study period.
