Can anyone explain to me how dangerous the white liquor leak in my town is?

I live two miles from here. Our water treatment plant is directly across the street from this site, and they are saying that tens of thousands of gallons of white liquor has spilled out and into the environment. Officials swear that everything is fine and we are all safe, but I'm not so sure...do you chemists agree that we are safe? Or should everyone stop drinking the water and leave?
