Believe me, you'll drink water if your life depends on it.

I am lucky enough to have an artesian spring just a couple miles away with the best drinking water I've ever tasted. I drink 1-2 liters a day, and prefer water over any type of soft drink.

I have 7 - 6gal hard plastic jugs at home I try to keep full ($7 at Wally World), and have never tasted the plastic. I have however tasted serious plastic in commercial water bottles packed away in my BOB in the car. They were stored in there for about 6 months and tasted pretty bad.

I don't have any real evidence either way about the dangers involved with chemicals seeping into the water. Anyone have a source they can cite that says something about that?

Regarding taste, keeping some packets of Kool-Aid in your BOB is a great idea. The sugar can give you a boost in an emergency and if you have kids, will make the water more palatable.
