The research results show that surface water quality has been being affected by wastewater from Phong Khe industrial clusters although the wastewater quality of Phong Khe industrial clusters now is better than in 2019 in some parameters such as BOD5, COD, TSS, Fe, NH4+, S2-. The surface water of Ngu Huyen Khe river has been improved significantly compared with the results in 2019. The water quality for the parameters of NO2, PO4, heavy metals, coliform were all good within the standard’s threshold, while the water quality for the parameters of BOD5, COD, ammonium were still 1.2-1.8 times over the threshold in standard QCVN 08:2015/BTNMT but improved compared to the result in 2019.
