Mianyang's Water Pollution

I've been reading a lot lately (in my China Studies book) that pollution is the biggest obstacle that the country has to face right now - and, of course, a couple days ago, we received news from half a dozen different people that Mianyang's water source has been contaminated. We've been told not to drink the tap water (which I never did anyway) and not to eat food at restaurants (only at the school cafeteria). Someone also suggested buying a lot of bottled water because the stores might start running out. We get supplied bottled water from the school anyways, so I'm not too worried.

Anyways, there's a news article here about it.
