Songkhla: The Director-General of the Department of Pollution Control (DPC) revealed plans to expedite the restoration of Songkhla Lake’s water quality after inspecting 11 locations and finding low oxygen and high ammonia levels in some areas. He expects that after waste management and city cleaning, water quality will gradually improve. He also plans to expedite the management of residual waste by separating it and incinerating it immediately.
According to Thai News Agency, Mr. Surin Worakithamrong, Director-General of the Pollution Control Department, revealed that the department is awaiting laboratory analysis results for Songkhla Lake water quality, including oil and grease, organic matter, coliform bacteria, total nitrogen, and fecal coliform bacteria. This in-depth examination follows samples collected on December 1st for a preliminary examination on December 1st, 2025. Additionally, samples were collected from U-Tapao Canal, Hae Canal, and canals in Ranot District, totaling 11 locations. The environmental laboratory analysis found that water quality in some areas does not meet Type 3 surface water standards, with the main deteriorating factors being low dissolved oxygen, high turbidity, and high concentrations of ammonia and total phosphorus. However, these values do not exceed pollution control standards.
Water quality is expected to gradually recover once waste management and area cleaning are completed. Specific rehabilitation plans are being considered for areas with deteriorated water quality to ensure effective and sustainable long-term restoration.
Regarding the large amount of waste remaining from the flooding in Hat Yai Municipality, which has been transported to a collection point at the “Black Bridge,” it is estimated that the total amount may exceed 25,000 tons.
The key principle is to expedite the removal of waste from the area to avoid burdening the public, and to expedite the opening of incinerators. The Director-General of the Pollution Control Department traveled to Hat Yai District today to provide technical advice on waste separation at the Saphan Dam rest stop, particularly organic waste, electronic waste, and hazardous waste. Proper separation can greatly enhance the efficiency of waste disposal.
