Pollution Control Department Corrects Water Quality Data Following Prachin Buri Fish Die-off
Thailand's Pollution Control Department has issued a correction regarding water quality analysis in Prachin Buri following a recent fish die-off, citing previous reporting errors.
The Pollution Control Department (PCD) under the Ministry of Natural Resources and Environment has officially corrected its previously released water quality data concerning a recent incident where fish died in the Ban Tham, Tha Tum, and Hat Nang Kaeo areas of Prachin Buri province. According to Khaosod Online, the department identified discrepancies in the initial reporting of ammonia and aluminum concentrations.
Following a review of samples collected on October 12 and 16 across nine locations, including tributaries and the main Prachin Buri River, the PCD released updated figures. The revised data indicates that dissolved oxygen (DO) levels in the river range from 2.5 to 7.5 milligrams per liter (mg/L), while ammonia levels are now recorded between 0.22 and 0.48 mg/L. Most heavy metal concentrations were found to be below detectable limits.
For residents and visitors in the area, this correction clarifies the environmental status of the river, though the exact cause of the fish mortality remains a subject of ongoing investigation. The PCD has announced plans to collect additional sediment samples to further analyze the riverbed conditions. While the water quality data has been updated, those living near or utilizing the river for recreational purposes should remain aware of official updates from local authorities as the investigation into the ecological impact continues.
