Farmers Warn as Arsenic Levels Spike in Mae Sai River
Farmers in Mae Sai, Chiang Rai, are alarmed after arsenic levels in the Sai River were found 28 times above safety limits, threatening their rice crops and health. With no alternative water source, they can only limit exposure and urge authorities to address the pollution source in Myanmar. Officials say tap water remains safe after treatment, and recent tests show arsenic levels have dropped back to normal.
Farmers in Mae Sai district, Chiang Rai province, expressed concern after arsenic in the Sai River was found to be 28 times above the standard and lead more than five times over the limit. They said they have no alternative water source for their rice paddies and can only minimize contact with the contaminated water. They called on the government to tackle the pollution at its source in Myanmar, warning that without action the contamination could endanger health, livelihoods, and fish, which are already developing skin sores. A team of reporters visited the regional waterworks facility in Mae Sai and confirmed that water from the river is still being used to produce tap water under normal conditions. The facility manager said the water is treated to meet standards and tested twice monthly, with recent tests showing arsenic levels have returned to normal, ensuring the tap water is clean and safe.
