Three Gorges dam threaten by debris
Thousands of tonnes of rubbish washed down by recent torrential rain are threatening to jam the locks of China’s massive Three Gorges dam and is in places so thick that people can stand on it. Chen Lei, a senior official at the China Three Gorges Corporation said that 3,000 tonnes of rubbish was being collected at the dam everyday, but there were still not enough resources to clean it all up. “The large amount of waste in the dam area could jam the mitre gate of the dam,” said referring to the gates of the locks which allows shipping to pass through the Yangtze river. The river is a crucial commercial artery for Chingqing and other areas in China’s less-developed western interior provinces. 
Some 50,000 square meters of the water’s surface had been covered by debris washed down since the start of the rainy season in July. The rubbish is around 60cm deep and in some part so compact that people can walk on it. The three Gorges dam is the world’s largest hydro power project and was built partly to tame the flooding along the Yangtze which filled over 4,000 people in 1998. The dam has cost over £24 billion and forced relocation of 1.3 million people to make way for the reservoir. Towns, fields and historical and archaeological sites has been submerged. Environmentalist have warned for years that the reservoir could turn into a cesspool of raw sewage and industrial chemicals backing on to Chongquing city, fearing that silt trapped behind the dam could cause erosion downstream.

Pollution renders quarter of Chinas water unusable
Almost a quarter of China’s surface water remains so polluted that it is unfit even for industrial use, while less than half of total supplies are drinkable, data from the environment watchdog showed on July 26. Inspectors from China’s Ministry of environmental Protection tested water samples from the country’s major rivers and lakes in the first half of the year and declared just 49.3 per cent to be safe for drinking, up from 48 per cent last year, the ministry said in a notice posted on its website. 
China classifies its water supplies using six grades, with the first three grades considered safe for drinking and bathing. Another 26.4 per cent was said to be categories IV and V – fit only for use in industry and agriculture – leaving 24.3 per cent in category VI and unfit for any purpose. Despite tougher regulations over the last decade, the ministry has struggled to rein in the thousands of small paper mills, cement factories and chemical plants discharging industrial waste directly into the country’s waterways, and the overuse of fertilizers has also left large sections of China’s lakes and rivers chocking with algae.
