Abstract

• Bago City is situated on the Bago River. Some parts of this cityis frequently being flooded in rainy season. The comparative studies on the quality of water body sites in the flooded and non-flooded areas of Bago City, during the time frame (2014-2016) have been studied. Flooding causes changes of water quality. The physicochemical properties (pH, temperature, DO, COD, BOD, total alkalinity, total hardness, total dissolved solid, nitrate nitrogen, phosphate, chlorinity, salinity and turbidity were determined on a quarterly basis throughout each year. Microbiological properties (total coliform and E. coli) of the water samples were also determined. Atomic absorption spectrophotometric method was used to determine the toxic elements (As, Pb, Hg, and Cd). The qualities of water resources from flooded and non-flooded areas in Bago City and its vicinity have been assessed.
