          EGAT’s Vajiralongkorn Dam said the water quality in the dam returned to normal after a natural phenomenon called turnover during the temperature decline which had made the water turbid and smelly.

          Dr. Ruamsap Kaneda, Director of Regional Environment Office 8th (Ratchaburi) of Pollution Control Department, Mr. Neramit Leong-aramfa, Senior Deputy District Chief acting District Chief - Thong Pha Phum, Mr. Prathet Boonyong, Mayor of Thong Pha Phum Sub-district, and Mr. Amorn Kaensaree, Director of Vajiralongkorn Hydro Power Plant of Electricity Generating Authority of Thailand (EGAT) went to collect water samples from the reservoir of Vajiralongkorn Dam, as during the last weekend, the water in the dam had become turbid and smelly. Presently, it has been found after the inspection that the water looks quite clear, while the quality of surface water is normal. It is expected that everything will return to normal within a few days.

          The water in Vajiralongkorn Dam was turbid and smelly because of a natural phenomenon called turnover. There were two factors that drove the turnover, namely the fast decline of temperature in Thong Pha Phum District to 13.5 degree Celsius and the low level of water in the reservoir, around 52% of its storage capacity which was lowest during the past 5 years. These caused the temperature of surface water to decline and its density to increase, making the surface water plunged to the bottom. At the same time, the bottom water moved up to the surface and brought up sediments, which made the water smelly. However, this natural phenomenon lasted only a short period.
