Chiang Mai Governor Thotsapol Phueanudom visited Ban Tha Ton Pier in Mae Ai District to monitor the contamination situation in the Kok River. The latest and 10th random test for heavy metal contamination in aquatic animals, vegetables, and water from the Kok River showed no presence of arsenic, cadmium, or lead. Mercury was detected at a low level of 0.12, which falls within the safety standard and is considered safe.
In addition, 147 wells within a 25-kilometer radius of the Kok River, along with tap water sources, were also tested. The results showed no heavy metal contamination exceeding safety standards.
