Arsenic, Drinking Water and Environmental Health in Myanmar Khin, Phyu Phyu Aye, Min Maw Kyaw, Zin Thant Arsenic, environmental, Schwertmannit, AyeyarwadyDivision The quality of drinking water is a powerful environmental determinant of health. Every stream, lake, river and aquifer can be used as a drinking water source. Protecting these sources from contaminants is a major national priority in protecting public health. Arsenic is one of the most important inorganic contaminants found in drinking water. Drinking water rich in arsenic over a long period leads to arsenic poisoning （arsenicosis）. The most effective preventive measure is supply of drinking water with permissible arsenic concentration. In 2002, from 25 villages in Ayeyarwady Division, 66.6% of well water has high arsenic levels. In 2013, 123,962 drinking water samples in 17 townships were tested for arsenic contamination in Ayeyarwady Division and 6.22 % was 51μg/l-100μg/l and 1.98 % was > 100μg/l. Among a variety of technologies for the treatment of arsenic in water, Schwertmannite is a natural mechanism to remove arsenic. In Aung Thapyay village, Zalun Township, Ayeyarwady Division, water samples from 12 arsenic contaminated tube wells were filtered by Schwertmannite and the concentrations of 89.15 -293.49 ppb were reduced to 12.32 -30.87 ppb. Now the project for promoting environmental health in arsenic contaminated area in Myanmar has been started in Thabaung Township, Ayeyarwady Region and project period is 2015 to 2018.
