In this research, brackish water samples in Dawei river of Talaingya village, Yephyu Township and Thinbawseik quarter, Dawei Township, Tanintharyi region were collected in September, 2017. Location of the brackish water samples Talaingya village, Yephyu Township and Thinbawseik quarter, Dawei Township, Tanintharyi region were 14°17'52.58"(N) 98°11'27.33" (E) and 14° 04' 18.99" (N) and 98° 11' 4.02"(E). Determination of water quality parameters; pH values by pH meter, dissolved oxygen by DO meter, temperature by temperature sensor built-in probe in DO meter, total dissolved solids by gravimetric method, total suspended solids by filtration method, chemical oxygen demand (COD), alkalinity, total hardness, salinity, chlorinity by titrations method were carried out. Mineral contents of brackish water sample were determined by atomic absorption spectrophotometric (AAS) method.
