Abstract: The study area, Kyeemyindaing Township, is situated in the western part of Shwedagon-Mingaladon anticlinal ridge. The topography of the study area is flood plain and low land flat area. The major drainage is Yangon River which flows along the western part of area from north to south. Tidal flat and channel are found along Yangon River. Therefore, this area may be intruded by salt water from the river. At present, there are two reservoirs and some tube wells are provided as the existing main sources of water for the study area. The daily estimated total amount of water supply from these tube wells is approximately 3 mg/d. According to the data of pumping test, the discharge rate Q is 309.4215 m³/d and transmissivity KD is 435.6377 m²/d. Fifteen groundwater data are classified by Piper methods. According to the Ghyben-Herzberg relation method, the saltwater interface rises up to higher level when pumping the well. If the pumping is continued for a long time, the saline water interface will gradually rise up to higher level and eventually, it will reach the well. So, it is necessary to control the excessive pumping of well to prevent the saltwater intrusion in the future.
