Bangkok: The Pollution Control Department (PCD) has confirmed that recent images depicting the Pa Sak River with black water, which circulated widely on social media, were created using artificial intelligence (AI) and do not reflect reality. The department is urging the public to verify information from reliable sources before sharing it online, as part of its broader efforts to prevent the spread of misinformation.
According to Thai News Agency, Dr. Surin Vorakitthamrong, Director-General of the PCD, stated that the department is intensifying its initiatives to combat illegal waste dumping. These efforts include the use of aircraft in tandem with ground inspections to monitor high-risk areas. This strategy has been implemented in coordination with the Ministry of Natural Resources and Environment (MNRE), under the guidance of Minister Suchart Chomklin. The department is also developing a spatial database to effectively track pollution sources and bolster law enforcement efforts.
The PCD previously conducted aerial surveys in the Chonburi and Chachoengsao provinces. The data collected from these surveys will aid in detailed investigations and the pursuit of strict legal actions against violators, aiming to mitigate environmental and public health impacts.
Dr. Surin addressed the misinformation regarding the Pa Sak River in Saraburi Province, confirming that investigations by the Pollution Control and Environmental Office Region 7 found no evidence of black water or white foam as depicted in the viral images. He emphasized the importance of public and media discretion in sharing information to prevent societal misunderstanding and panic.
Moreover, the PCD continues to monitor heavy metal contamination in the northern region, particularly in the Salween River and its tributaries in Mae Hong Son Province. Recent tests revealed arsenic levels exceeding surface water quality standards, prompting advisories for the public to improve water quality before consumption and avoid certain water activities.
Sediment quality tests have also shown arsenic levels surpassing reference limits, with other heavy metals like nickel, zinc, copper, and mercury present in some areas. The PCD is committed to ongoing monitoring and will provide periodic updates on the ecosystem's health.
Collaborative efforts with the United Nations Industrial Development Organization (UNIDO) and other international partners are underway to address arsenic contamination in northern Thailand. The PCD is also working with Australia and China to enhance transboundary pollution management and environmental quality monitoring.
In the eastern region, the PCD is investigating wastewater issues in the Amata City Industrial Estate in Rayong Province. This includes inspecting high-risk factories and analyzing water and sediment samples to identify pollution sources and enforce legal measures. Preventative strategies will be implemented to prevent future occurrences and reinforce environmental protection.
