Abstract

• The research area is underlain by the Recent Pliocene age. It is mainly composed of yellow to red, fine to coarse sand, gravel, yellow to red of lateritic soil and yellowish clay. The main aquifer is Irrawaddy aquifer and Alluvial aquifer. The specific yield of the groundwater is 1000 to 2500 gallons per hour for 4 inches diameter well and the depth of the water-bearing horizon ranges from 40 ft to 350 ft in the aquifer. The concentration of hydrogen ions (pH) is between 6.5 and 7.7. Mostly, the total dissolved solids are 1900 ppm in the research area. Total salinity is low and electrical conductivity (E.C) is 160-2820 μ mho/cm. The concentration of Chloride ions is widely distributed in most of the water of the studied region and the amount present in groundwater is relatively higher than in other anions. The results of chemical data analyzed by the SSP% method, the SAR method and the MAR method show that some tube wells can be assessed as not suitable for use as irrigation water. Kurlov’s Method and PIPER method can be classified the water types, drinking water, domestic use and Irrigation water. If high amount of Iron concentration, it can be reduced of amount with aeration methods and sand filtering methods. According to the KURLOV’s Method and Piper Method, Water Types can be classified into 6 water types. According to the above methods and the WHO Drinking Water Standard, the data can assess whether the groundwater of the research area is suitable for drinking water, domestic use, and irrigation water, except that some tube wells are not suitable.
