Abstract

• Analysis of water sample is one of the major issues during water quality monitoring of either surface or ground water sources. The objective of this study was to determine elemental concentration, some properties of ground water of hand-dug wells in one village of Mawlamyine district and two villages of Thaton district at Mon State, Myanmar and also their possible effects on the health of the inhabitants. Apparently, ground water in most countries is contaminated by the large number of chemical fertilizer used in our daily life and disposal of massive industrial effluents and mining activities. These wastes have negative effects on human health. Different waste products have different affects depending on their locations and kinds. It is essential to examine the water quality to avoid its hazard on local people. In this paper, ground water samples were analyzed using atomic absorption spectroscopy (AAS) to determine the concentration of some dissolved elements. The metal analysis is done to detect (i) arsenic (ii) lead (iii) cadmium (iv) iron (v) magnesium (vi) copper (vii) zinc using AAS method and some water parameters such as (i) pH (ii) electrical conductivity, (iii) temperature. The results obtained are compared with guidelines for drinking water quality World Health Organization (WHO) (2011). All the observed values except Cd are within the safe limitations (WHO). The observation from this job revealed that the measured pH values were in the range of 7.1 to 7.5, the values of electrical conductivity were found 43 to 625 μS/cm. The achieved turbidity values of all ground water samples are less than 5.
