Abstract

• The study area, Mahlaing Township is located in the central dry zone of Myanmar. Historically this area has been hydrogeologically renowned for its high salinity, low groundwater yielding aquifers and low success rate in locating potable water suitable for irrigation and human consumption. Although this is the case in some of the fractured marine shale and fine sandstone aquifer of the Obogon and Kyaukkok Formations of Lower to Middle Miocene age. The study area is classified into two types of aquifer. There are Irrawaddian aquifer and Peguan aquifer. The recovery test shows that the transmissivity of the Irrawaddian aquifer is (89.47 m2/day) in 4” diameter tube well and (2.8 m2/day) in 6” diameter tube well of Peguan aquifer.
