Citizens Networks Plan Protest Over River Pollution in Northern Thailand

CHIANG RAI – Local activists and civil society networks in northern Thailand are taking to the streets and waterways to protest a growing ecological crisis. For over a year, illegal mining activities in neighboring Myanmar have dumped heavy metals and toxic chemicals into shared rivers.

This pollution directly affects the health, water supplies, and livelihoods of thousands of Thai families in Northern Thailand.

To demand urgent solutions, the Network for the Protection of the Kok, Ruak, Mekong, Salween, and Kraburi Rivers organized a massive five-day protest march and boat rally timed with World Environment Day.

The movement aims to force the Thai government to take immediate action against cross-border pollution.

A 70-Kilometer Journey for Justice and Environmental Safety

The multi-day protest serves as both a political demonstration and a public education campaign. Organizers designed the route to follow the path of the contamination, highlighting how pollution flows from rural border towns into major urban centers.

The network structured the five-day event with clear geographic milestones:

May 31: The march began in Tha Ton Village in Chiang Mai’s Mae Ai District. Activists marched along the Kok River and held an evening public forum titled “One Year of Cross-Border Contamination in the Kok River.”
June 1: Protesters traveled from Wat Mai Mok Cham to Pha Tai School. The stop featured cultural events and a panel discussion called “Listening to Citizens: Concerns Over Toxic Contamination in Rivers and Solutions for Communities.”
June 2: The group visited Pha Khwang School to coordinate environmental awareness activities with local youth and community leaders.
June 3: Activists inspected flood-damaged areas at Khae Wua Dam Village in the Mae Yao sub-district of Chiang Rai, looking at how floods spread toxic river sediments into residential zones.
June 4: A strategic seminar took place at Huai Sai Khao Village to compile local data, personal testimonies, and policy recommendations.
June 5 (World Environment Day): The demonstration will culminate in a dramatic river rally. Protesters will board boats from the Mae Yao Municipal Office and travel down the Kok River to the Chiang Rai Provincial Hall.

Organizers expect at least 2,000 local citizens, farmers, and artists to join the final rally. The crowd will march under the banner “Five Rivers, Five Wounds” to hand an official petition to every Member of Parliament and Senator representing Chiang Rai.

Toxins in the Food Chain and Tap Water

Dr. Suebsakul Kijnukorn, an academic from Mae Fah Luang University, revealed that local joint committees have monitored the Kok River for a full year. The scientific findings are deeply alarming for public health.

The data shows a steady, heavy accumulation of dangerous, toxic heavy metals in the ecosystem. This pollution is no longer just in the water; it has seeped into river sediments, agricultural soil, local vegetables, fish, and municipal tap water systems.

The pollution threatens multiple sectors of northern Thai society:

Public Drinking Water: The contamination directly threatens more than 40,000 households that rely on the Kok River basin for daily running water and municipal consumption.
Agriculture and Farming: Over 100,000 rai (around 40,000 acres) of riverside rice fields and crop fields use this toxic water, threatening the Thai food supply chain.
Local Economics: Fishermen, riverside merchants, and tourism operators face severe financial losses as the river becomes visibly polluted and biologically hazardous.

Due to these widespread threats, activists argue that the Thai government must treat this environmental disaster as a national security emergency.

Activists Demand Direct Accountability From Top Cabinet Ministers

According to reports from Manager Online, the network refuses to accept mid-level bureaucrats as placeholders. They demand that top cabinet ministers personally visit Chiang Rai to hear the public’s grievances.

The petition addresses specific demands to five key government leaders:

Prime Minister and Interior Minister Anutin Charnvirakul: Activists are holding the Prime Minister accountable for his parliamentary policy addresses. They want him to fulfill promises to eliminate cross-border mining pollution. They are also demanding a 2-billion-baht budget to develop the Lao River as an alternative water source for tap water production, moving local water utilities away from the poisoned Kok River.
The Minister of Finance: Protesters want strict customs audits and border regulations. Currently, minerals mined illegally in Myanmar routinely pass through Thai border checkpoints before being exported to China, making Thai infrastructure part of the illegal supply chain.
The Minister of Foreign Affairs: The network wants stronger diplomatic pressure on Myanmar’s leadership. Although Thai officials raised the mining issue with Senior General Min Aung Hlaing, the Myanmar government claimed it could not access the mining zones because armed ethnic groups, such as the Wa and Karenni forces, control those specific border territories.
The Minister of Agriculture and Cooperatives: The ministry must provide immediate safety testing and financial compensation for the farmers working the 100,000 rai of at-risk agricultural land.
The Minister of Natural Resources and Environment: The ministry must deploy remediation technologies to clean the toxic heavy metals from the riverbed sediments.

A Call for Financial Compensation

Niwat Roykaew, the prominent head of the Love Chiang Khong Group, emphasized that a year of slow government bureaucratic responses has put thousands of human lives at risk.

Adding to this point, Somkiat Khuanchiangsa, the Director of the Living River Association, stated that the state must pay financial compensation to the affected communities.

Because the government failed to stop the cross-border pollution over the past 12 months, activists argue the state is responsible for the financial losses suffered by local farmers, fishermen, and businesses.
