Bangkok: Thailand is facing a severe environmental crisis as its major rivers have become contaminated with toxic substances originating from mining activities in neighboring countries. Mr. Patarapong Leelaphat, a Member of Parliament for Chiang Mai Constituency 8 from the People's Party, highlighted this pressing issue during a speech on World Environment Day. He urged the government to tackle the root causes of this pollution, which is impacting the health and livelihoods of Thai citizens.

According to Thai News Agency, the rivers affected include the Kok, Sai, Ruak, Mekong, Salween, and Kraburi rivers. These water bodies are contaminated with dangerous levels of chemicals and heavy metals, posing significant risks to people dependent on them for drinking water and agriculture. Contaminated rice, vegetables, fish, and shrimp are leading to an accumulation of toxins in the population. The pollution has forced the relocation of water treatment plants and the closure of businesses reliant on these water sources. Despite these alarming conditions, Mr. Patarapong expressed disappointment over the absence of government officials at a World Environment Day event in Chiang Rai, where civil society groups sought to voice their concerns.

The issue of transboundary water pollution has persisted through three successive governments, with little progress made in addressing it. Only two negotiations have taken place, with the most recent one occurring with Myanmar on August 20, 2025. However, no discussions have been held with Laos and China, two key players in the mining supply chain. A statement from the Chinese Embassy further challenged claims of heavy metal contamination, highlighting the Thai government's lack of action on the international stage.

Mr. Phatarapong proposed several measures to combat the crisis, including enacting legislation under Section 104 of the Mineral Act to prevent Thailand from becoming a transit route for polluting minerals. He suggested that Thailand should require import permits for important minerals and verify the environmental management practices of mines through a joint committee of Thailand, Myanmar, Laos, and China. This committee would develop an action plan for multilateral negotiations, ensuring that imported minerals do not harm the environment or pollute rivers.

He emphasized the urgency of the situation, stating that the government must decide whether to prioritize the well-being of its people or the interests of countries involved in mining activities. Despite the current government's inaction, the People's Party is committed to collaborating with civil society to address the issue. They plan to utilize the Sub-Committee on Transboundary Water Pollution and the Committee on Prevention and Mitigation of Natural Disasters and Public Calamities to safeguard public health and interests.
