We do Deer Park. I'm pretty sure that it is bottled fairly locally.
I know there is still some waste associated with the trucking and running the refridgeraton and heating in the dispenser, but I feel good knowing the large bottles are recycled/reused and it's GOT to be better to fill our (reusable) bottles up at home then buy them in the store and throw them away.
And if you still think it's unnecessary you must have never tasted Philadelphia city water.
