Besides, every year, over 15 million m² of waste water from domestic use is dumped into the river. “according to a reseach, the BOD5 concentration in the sampled water in Gia Bay, Thac Huong dam, Cau May has exceeded the limit from 1,08 to 9,5 times; COD exceeded 1,2 to 5,8 times, NH4 is 1,34 to 20 times over the standard figures. Meanwhile, the allowed number for all of the above substance is 0”

In addition, during the rainy season, the central part of Thai Nguyen city is usually flooded. The drainage system of the city is rather obsolete and substandard. Sewage from individual households, offices is released directly to the streams or rivers without treatment, which has worsen the pollution situation in the area.
