China launched nearly 8,000 water clean-up projects in the first half of 2017 with a projected total investment of 667.4 billion yuan (US$100.2 billion), the environment ministry said on Thursday. The projects were devised as part of a 2015 action plan to treat and prevent water pollution, and covered 325 contaminated groundwater sites across the country, the Ministry of Environmental Protection said in a notice. A total of 343 contaminated sites had been identified, meaning that 95 per cent had drawn up plans to bring water quality up to required standards, it said.

Large amounts of China’s water have been rendered unusable as a result of poorly regulated industrial expansion, overmining and the uncontrolled use of pesticides and fertilisers. With China desperate to increase supplies to guarantee future food and energy security, the government promised in 2015 to make significant improvements to the country’s major waterways and curb untreated waste water from highly polluting sectors like mining, steelmaking, textiles, printing and oil refining. Southern China’s million-tonne raw sewage problem The environment ministry said this month that overall water quality had improved in the first half of the year, although some regions registered an increase in substandard samples over the period. China grades its water in six bands, with the lowest “below grade 5” considered unusable even for industrial or irrigation purposes, and described as “black and stinky”. Of 2,100 “black and stinky” sites identified, 44.1 per cent had completed treatment projects in the first half of the year, the ministry said, adding that the provinces of Hebei, Shanxi, Liaoning and Anhui had fallen behind. China admits patchy progress tackling soil, water pollution, with some rivers worsening In a bid to protect rural water supplies, China also identified 636,000 square kilometres of land that would be made off limits to animal husbandry, and it shut 213,000 livestock and poultry farms in the first six months. The ministry also said 809 new household sewage treatment facilities were built in the first half, but added that the regions of Tianjin, Jiangxi, Inner Mongolia, Guangxi, Xinjiang, Hubei and Guangdong were behind schedule. Air pollution getting worse in north China even as government tries to crack down Beijing said on Wednesday that it had already appointed 200,000 “river chiefs” throughout the country as part of a new system aimed at making local officials more accountable when it comes to improving water quality and curbing pollution.
