BANGKOK, Thailand – The government is stepping up efforts to address pollution in Chiang Rai’s Kok River, ordering further testing to assess potential risks to public health and the environment. Prime Minister Anutin Charnvirakul has instructed relevant agencies to test river water for contaminants, test aquatic animals for safety for consumption, and assess soil quality in rice-growing areas. The findings will help public health authorities evaluate possible exposure risks and advise affected communities.
Deputy Government Spokesperson Lalida Persvivatana announced on November 10 that the Pollution Control Department has established approximately seven water quality monitoring stations and is preparing equipment to speed up on-site testing. The department will conduct additional inspections when the river becomes unusually turbid to determine whether the water remains suitable for tap water production. If testing finds the water unsuitable, the Provincial Waterworks Authority will be required to secure alternative sources to maintain public supplies.
Natural Resources and Environment Minister Suchart Chomklin also detailed plans to work with authorities in Myanmar and Shan State to address cross-border pollution. The proposed cooperation includes joint water-quality monitoring, heavy-metal testing, and possibly installing upstream monitoring stations. Discussions are underway to improve coordination and identify potential contamination sources, though no formal agreement has been reached.
Meanwhile, the government is reassessing the proposed Wang Tanot Reservoir in Chanthaburi, which would provide additional water for agricultural communities. The Royal Irrigation Department must review the reservoir’s size, layout, and potential environmental impacts, and make changes if the current proposal threatens protected areas. (NNT)
