Prachinburi:The government is conducting an urgent investigation into wastewater issues and fish deaths in Prachinburi province, with findings expected within a week.

According to Thai News Agency, the investigation was prompted by reports of fish dying in cages and a rainbow-colored oil slick in the Prachinburi River. The Deputy Spokesperson for the Prime Minister's Office, Ms. Lalida Periswiwatana, emphasized the government's commitment to resolving water quality issues that have alarmed the public, particularly in the Sri Maha Pho district.

Initial investigations have revealed that the locations of the fish deaths and the oil slick differ. Fish farms in the Ban Tham, Tha Tum, and Hat Nang Kaeo subdistricts of Si Maha Phot district, and Bo Thong subdistrict of Kabin Buri district, reported low dissolved oxygen levels, which may be linked to floodwaters and organic pollution. The oil slick, found in the Hua Wa subdistrict, originated elsewhere and is not currently believed to be the cause of the fish deaths. Further analysis is underway to confirm these initial assessments.

Samples of water and fish are being tested for heavy metals and ammonia to determine potential contamination from industrial sources. The Pollution Control Department has found high petroleum hydrocarbon levels near an industrial waste landfill close to the oil slick location. Coordination with the Department of Industrial Works is ongoing to trace the pollution source and assess environmental impacts.

Ms. Lalida reassured the public, especially fish farmers, that the investigation is thorough and evidence-based, avoiding premature conclusions about the causes. The government aims to restore public confidence through accurate scientific analysis and responsive measures. The public is advised to avoid contact with contaminated water and rely on official updates from government agencies.
