The results of water quality monitoring [9] show that the water quality of Thai Binh province is mainly polluted by COD, BOD5, NO2-, NH4+, PO43-, Coliform distributed in the area near Thai Binh city and areas of small rivers and inland rivers where large amounts of water are received daily from domestic wastewater, urbanization process, industrial parks, craft villages ... For 5 years (period 2015 - 2019), pollution also occurred locally at NM15 water quality monitoring points in Thai Binh city regularly at heavy pollution with the smallest water quality index WQI <
25. NM16 monitoring point in Thai Binh city area, NM23 in Tien Hai district water quality is at a bad level with the smallest water quality index WQI <
50. On the main tributaries during flood season and dry season water quality remains at a good level with most monitoring points having a WQ1 value of >
75, there are no points that are heavily polluted.
