However, there are still some areas with polluted surface water and they are hot spots for water environmental pollution. Water quality of rivers and canals in the irrigation systems of Hai Phong and Ninh Bỉnh is showing signs of serious pollution such as Re river (An Hai irrigation system)
Kien Giang river (South Thai Binh irrigation system)

The main cause of the above situation is lack of control and thorough treatment of discharge wastewater sources, especially wastewater from domestic activities, wastewater from craft villages ...This paper presents the assessment of water quality changes based on the calculation of the Water Quality Index (WQI) for the coastal irrigation systems of the Red River Delta. The assessment result will be the basis for proposing measures for water resources management and protection in the coastal irrigation systems in the Red RiverDelta for agricultural production and domestic
