Three Gorges reservoir water 'clean again'

Shanghai Daily, August 18, 2014 Adjust font size:

Data collected yesterday showed all pollution indicators had been brought within safety standards, suggesting that the water is non-toxic, it added.

Staff will keep monitoring water quality while officials formulate plans to resume supplies from Qianzhangyan Reservoir.

This will be carried out once health authorities confirm that the water is safe to drink, added the local government.

Qianzhangyan Reservoir, with a capacity of 4.05 million cubic meters, is 15 kilometers from the Yangtze River and usually provides drinking water for some residents in three nearby towns.

Supplies to 50,000 people were affected by the pollution, Xinhua news agency reported earlier.

Investigations by Wushan County and neighboring Shijian County in Hubei concluded that the pollutants -- sodium ethyl xanthate and a foaming agent -- came from a sulfur concentrate washery in Jianshi County. It was closed on Thursday.

Chongqing’s environmental protection bureau said there were toxic levels of organic matter in the water.

Supplies were brought in for affected residents and alternative reservoir supplies have since been diverted to most households.

Work is ongoing to ensure all are connected to alternative mains sources by Wednesday, said the county government.
