Despite thousands of dead pigs floating in Shanghai's Huangpu River, the water is supposedly safe to drink according to the Chinese government, at least after passing through Shanghai's treatment system.
Filtration systems might be able to handle a normal load of filth in the water of the Huangpu River, but 6,000 dead swine may be pushing it, Julian Fyfe, a water quality research consultant at the University of Technology Sydney, told CNN. However, the Shanghai water treatment system may be able to minimize the risk.
"If they are chlorinating heavily, which a lot of places may do, especially if they've got a very polluted water body to start with, then the effects could potentially be small," Fyfe said.

However, if I was visiting the area, I think I'd stick to pijiu, Chinese for beer. Or bottled water, as many of Shanghai's 23 million residents are doing.
What about those who can't afford bottled water? Adding extra bleach to tap water would be a cheaper alternative to bottled water, but that would only serve to kill pathogens, not filter out toxic chemicals.
