Surface water quality in China has improved over the past year. More samples taken from rivers and lakes meet the standards fit for human use, the Ministry of Environment reported on Monday, January 7.
Beijing has expanded its campaign to combat air and water pollution, seeking to clean up black streams flowing through Chinese cities and improve water quality of its nature reserves.

In 2018, water quality improved in most of China’s major waterways, including the Huai, Yangtze and Pearl Rivers. However, rivers in Northeast China, such as the Liao and Songhua became even more polluted than in 2017.
China has promised to take measures to significantly reduce the amount of industrial wastewater flowing into the Bohai Sea in the northern part of the country.
According to the Ministry of Ecology and Environment (MEE), last year, 71% of the 1,940 water samples from China were considered grade III or better, meaning they were suitable for drinking and fishing. This is 3.1 percentage points more than in 2017.
Meanwhile, the amount of water below grade V that cannot be used in agriculture or industry, decreased by 1.6 percentage points to 6.7% in 2018.
The main water pollutants were phosphorus and ammonium nitrate from industrial wastewater, pesticides and organic fertilizers.
