The water quality and pollution sources assessment of Surma river, Bangladesh using, hydrochemical, multivariate statistical and water quality index methods

Currently, the water pollution is an important issue in Bangladesh as well as in the world. The Sylhet city in Bangladesh is suffering from lack of structured sewerage and drainage systems with somehow improper management of solid wastes. Consequently, such wastes are discharged into the nearby Surma river through different sources responsible for degrading the quality of water. Thus, this study focuses on exploring the present water quality of Surma river applying the hydrochemical, multivariate statistical methods, and also with the help of the Water Quality Index (WQI) analysis. Also, recognize the potential pollution sources of water in the study area. The outcomes show that the average values of some components such as pH, Dissolved Oxygen (DO), Iron, Total Dissolved…
