Abstract

• The research area, Bago is situated on the Eastern Part of the Bago Yoma. The topography of the research area is slight moderate plain and its gently slope towards the east. This area is about 228.712 square kilometer. The sources of water supply are water from tube well and reservoir. The main aquifer in western part is Irrawaddy Formation and in the eastern part it is Alluvial Aquifer. The yield of Irrawaddy is 500 to 2000 gallons per hour. pH falls between 6.5 to 7.7. TDS falls in 50-340 ppm. Total salinity is low and electrical conductivity (E.C) is always not more than 530 μ mho/cm. Iron content is rising up to 3 ppm. The results analyzed by KURLOV’S METHOD, SSP% method, SAR method MAR method, RSBC method, TDS and PIPER method can be classified the water types, drinking water, domestic use and Irrigation water. According to the above these methods and WHO Drinking Water Standard, the groundwater of the research area is suitable for the drinking water, domestic uses and Irrigation water.
