From BBC News:
Water supplies to about 200,000 people in central China have been contaminated by pollution, which has turned branches of a major river system red.
At least three tributaries of the Han river – a branch of the Yangtze – have been affected.
State media reported high levels of chemicals in the water.
China is increasingly concerned about its environment. A recent ban on plastic bags has led to the country’s largest bag factory shutting down.
