Abstract Water quality is one of the most important health indicators in a freshwater ecosystem. The present study concerns the variation of the seasonal water quality index of water bodies in Yangon. The purpose of the present study is to evaluate the quality of surface water in five locations in Yangon (Twente Canal, Hlaing River, Yangon River, Pazundaung Creek, and Bago River) using water quality index (WQI). To assess the water quality of five water bodies, the physico-chemical characteristics and microbiological parameters of selected water samples were determined. The obtained analytical data were compared with surface water quality guidelines published by the EPA (2017). Moreover, the measured results of all water samples are also compared seasonally. The Weight Arithmetic Water Quality Index method was used to compute the values of WQI for five study locations. Using data on physical, chemical and microbiological parameters, the water quality index of the water sample was calculated. The calculated values of WQI were found to be from 33.93 to 44.95 in the rainy season, from 33.53 to 41.50 in the cold season, and from 45.54 to 72.95 in the hot season for five water sources. Based on the WQI values and water quality gradings, the water quality of water bodies in Yangon is good (or grading B) in the rainy and cold seasons. In the hot season, it is still good for locations 1 and 2, but it is poor (or grading C) for locations 3, 4, and 5. |
