Shanghai water supply hit by 100-tonne wave of garbage

Ships are suspected of dumping waste upstream on China's Yangtze river before it floats into a key city reservoir

Medical waste, broken bottles and household trash are some of the items found in more than 100 tonnes of garbage salvaged near a drinking water reservoir in Shanghai.

The suspected culprits are two ships that have been dumping waste upstream in the Yangtze river. It has then flowed downstream to the reservoir on Shanghai's Chongming island which is also home to 700,000 people.
