Authorities Investigate Mass Fish Die-off in Pathum Thani Canals
Minister of Natural Resources and Environment Suchart Chomklin has ordered an urgent water quality assessment following reports of dead fish and foul-smelling water in Pathum Thani.
On October 17, 2026, Khaosod Online reported that Minister of Natural Resources and Environment, Suchart Chomklin, expressed concern over a significant number of dead fish discovered in the Khlong Song and Khlong Rangsit Prayunsak canals in Pathum Thani province. The water in these areas has reportedly turned dark and emits a strong odor.
In response, the Pollution Control Department (PCD) was directed to conduct an immediate environmental assessment and coordinate with local authorities to address the pollution. Dr. Surin Worakitthamrong, Director-General of the PCD, stated that officials from the Regional Environment and Pollution Control Office 6 inspected five locations on October 16. Testing at the Khlong Song site, where the fish mortality was highest, revealed a dissolved oxygen (DO) level of 0 mg/L, indicating that the water is currently unable to support aquatic life. Other readings included a turbidity level of 1,295.1 NTU.
For residents and visitors in the area, the Ministry has issued a warning to exercise caution and avoid using water from these canals to prevent potential health risks. While the immediate cause of the oxygen depletion is under investigation, the authorities are working to identify the source of the contamination. Further updates are expected as laboratory analysis of the collected water samples continues.
