Abstract:

This paper studies the water quality degradation of Sat river - the section flowing through Hai Duong province and waste sources pollute Sat river water. Five surveyed locations along Sat River were identified, and water samples were taken for five consecutive years from 2016 to 2020. Water samples were analyzed in the laboratory with the criteria and methods regulated by QCVN 08:2015/BTNMT. The analyzed results showed that the Sat river water had five parameters frequently exceeding the B1 limit value of QCVN 08 - MT: 2015 BTNMT consisting of DO, NH4+, PO43 -, COD, and BOD5. Two main causes of Sat river pollution conclude of pollutants available in the river upstream and from many sources of domestic wastewater, industrial wastewater, and agricultural wastewater in Hai Duong province without proper treatment. To improve the water quality of Sat river, the collection and treatment of wastes at the source must be thoroughly treated with reasonable waste management.
