Saraburi: The Pollution Control Department (PCD) has launched an urgent investigation into the source of contamination in the Huai Takhe reservoir, where chemical odors have been detected at all inspection points, and has vowed to pursue legal action against any culprits identified for causing environmental harm.
According to Thai News Agency, Mr. Surin Worakitthamrong, Director-General of the PCD, revealed that a field inspection was conducted in Khlong Ket, Khlong Nong Nam Khiao, and Huai Takhe, located in the Pak Khao Sar Subdistrict of the Mueang District, Saraburi Province. The inspection was prompted by reports of foul odors and wastewater in the area. Initial findings indicated that the water in these sources was dark, murky, and emitted a strong chemical-like smell. Field analysis showed total volatile organic compounds (TVOCs) ranging between 2.5 and 26 parts per million (ppm), with high electrical conductivity (EC) detected upstream, suggesting contamination from dissolved substances.
The Director-General stated that water samples were collected to analyze 23 water quality parameters, including heavy metals, dissolved substances, and organic matter. Results from the laboratory analysis are expected within a week. Additionally, air samples were collected from three locations to assess volatile organic compounds (VOCs) in the atmosphere, covering 62 parameters to evaluate the impact on the environment and public health.
In an effort to trace the source of pollution, officials visited nine locations, including six industrial plants and three businesses, collecting water samples for comparison with natural water sources to pinpoint the contamination origin.
Mr. Surin reassured that the tap water quality, as inspected from the Saraburi Municipal water pumping station, meets the potable water standards set by the Department of Health in 2020. On-site inspections confirmed that sluice gates were closed to prevent contaminated water from entering the Pa Sak River, ensuring no immediate impact on public water consumption.
The Director-General emphasized that if the investigation identifies the perpetrators, strict legal measures will be enforced. This includes criminal charges under relevant laws, with penalties of up to 5 years’ imprisonment, a fine of up to 100,000 baht, or both, along with claims for environmental damages under Sections 96 and 97 of the National Environmental Quality Promotion and Preservation Act B.E. 2535 (1992).
The PCD is committed to using scientific evidence in its thorough investigation of the chemical contamination and will collaborate with specialized research institutions if needed, to ensure those responsible are held accountable.
