The Nha Trang City administration has urged Khanh Hoa Province officials to devise a strategy to mitigate saltwater intrusion in the Cai and Quan Truong Rivers and oversee upstream waste sources to prevent the first river from being polluted.

The provincial People’s Committee tasked the Khanh Hoa Department of Natural Resources and Environment with working with relevant units to weigh the proposal from the Nha Trang administration to promptly address the problem.

All efforts are directed toward improving the water quality of the Cai and Quan Truong Rivers in the city, which is the capital of Khanh Hoa in south-central Vietnam.

The administration previously sent a report on potential severe saline intrusion into the two rivers and a high risk of pollution from upstream waste sources.

Saltwater has intruded into the two rivers, leading to the concentration of chlorides in some of their sections soaring.

Therefore, the city proposed the provincial People’s Committee direct relevant units to survey the entire Quan Truong and Cai Rivers and take action to fight saline intrusion.

Besides, the administration cited water quality indices announced by the provincial department in March as saying that the quality of the Cai River water environment was assessed as being poor, with biological oxygen demand (BOD5) and chemical oxygen demand (COD) indices lower than the standard levels.

The Nha Trang People’s Committee attributed the poor water quality of the Cai River to upstream waste sources and the weak waste management in Dien Khanh and Khanh Vinh Districts. 

To ensure the quality of water that will be provided for local water purification facilities, the city suggested that the provincial administration and department push local authorities in the two districts to review, inspect, and handle waste sources to reduce the pollution in the Cai River and other neighboring areas.
