Pollution Testing in Prachin Buri River Reveals Low Heavy Metal Levels
Authorities have released initial water quality findings following reports of fish deaths in Prachin Buri, noting low levels of heavy metals and suggesting recent flooding may have diluted pollutants.
On October 23, 2026, the Pollution Control Department (PCD) of Thailand released findings regarding water quality in the Prachin Buri River. This investigation follows reports of fish deaths in the Tha Tum, Ban Tham, and Hat Nang Kaeo sub-districts of Si Maha Phot district, which impacted local cage-fish farming operations.
Dr. Surin Worakitthamrong, Director-General of the PCD, stated that officials collected water samples from nine locations across the river and its tributaries on October 12, 2026. The analysis revealed that heavy metal concentrations in both the water and fish samples remain at low levels. Officials hypothesize that widespread flooding in the region may have contributed to the dilution of potential pollutants.
For residents and visitors, these findings suggest that while immediate toxicity levels appear low, the investigation is ongoing. The PCD is now preparing to conduct further testing on riverbed sediment to identify the precise source of the contamination and the underlying cause of the fish mortality.
While the current data indicates that water quality parameters, such as dissolved oxygen levels, are being monitored, the situation remains under investigation. Residents are advised to follow official updates from the Prachin Buri provincial authorities regarding water safety and the consumption of local aquatic products until further comprehensive results are released.
