Arsenic in Chiang Rai's Sai River halts Mae Sai tap water
Tap water production in Mae Sai, Chiang Rai was briefly suspended after raw water from the Sai River showed arsenic at 0.30mg per litre, far above the 0.01mg standard, along with extreme turbidity. Normal supply has resumed, but about 60 households in higher parts of Ban Pha Daek were still without tap water and are being supplied by truck. A Mae Fah Luang University lecturer is urging Thailand and Myanmar to act on mining-related contamination in the Kok, Sai, Ruak and Mekong rivers.
