Hydrogeological Investigation of Thagaya-Myohla area, Yedashe Township, Bago Region Kyi Hlaing Nwe Nwe San The study area is located in the Thagaya-Myohla Townships, Taungoo District, Bago Region. It is between North Latitude 19•16′4.8″ N to 19•25′40.8″ N and East logitude 96•12′57.6″ E to 96•24′7.8″ E and refers to one-inch topographic map of this area is No.94A/3 and 94A/7. It has tropical monsoon climate with average monthly rainfall of about 167mm (6.64 inches) which may reach as high as 471mm (18.56 inches) during rainy season. The major sources of employment include agriculture, horticulture and animal husbandry, almost 80% of the workforce. On the basis of geological conditions and stratigraphic position, three types of aquifers are found, younger alluvial aquifer and two older alluvial aquifers. In accordance with their morphological characteristics and occurrence, younger alluvial aquifer (Sittaung River valley deposit), older alluvial aquifer can be sub-divided into older alluvial aquifer unit I (Fan deposit from Bago Yoma) and older alluvial aquifer unit II (Fan deposit from Eastern Highland). The groundwater flow direction of the area is from west to east in the western part of the study area towards the Sittaung River and from east to west in the eastern part of the study area towards the Sittaung River.The water samples are collected from 15 wells and were subjected to analysis for chemical characteristics. Some water samples were found to be within in WHO guideline value. The iron values in the study area exceed the standard limit and other ions values fall under the permissible limits. The suitability of groundwater for irrigation was assessed from (TDS, EC, SAR, MAR, Na% or RSC). Most of the groundwater samples in this area fall in the suitable range for irrigation purpose. 2025-03-03 https://meral.edu.mm/records/12746
