That sucks, I was not aware of that. In the US we don't even know where the hell our tap water comes from in the first place so its not an issue. =D
I live in Atlanta, GA. Most of us should know where our water originates because every year we are in a new drought. They will always start off the news of this drought by saying Lake Lanier is 15 feet below full and that the Chattahoochee river is drying up (and full of toxic substances).
It really sucks that we have millions of people living in an area totally dependent on a man-made lake initially designed for flood control.
