First let me indeed make it clear that we only very rarely use bottled water. We have good well water at our house and use stainless steel water bottles for portable drinking. But every so often, of course, we're out and we realize we need water but we forgot to bring any.
Anyway, last year hubby bought a large bottle of spring water, a good 2 liters, for sailing. He didn't actually end up using it. It's been sitting in our cupboards for the past year, unopened and unused.
We're tidying out the cupboards, and hubby wants to just dump the water since he's not comfortable with something that's been sitting in plastic for that long. I think we should use it, because we've already spent the money on it so why waste it when it's probably fine? To my understanding, the main issue with plastic is when it's heated, which this hasn't been. Also, to my thinking, you never know how long a bottle of water has been sitting on a supermarket shelf. Theoretically it could be just as 'old' from bottling time to drinking time, but if it's "new" in terms of just recently purchased you're not going to have any hesitation drinking it. Just because it's been sitting in our cupboard instead of in some warehouse doesn't make it any worse. Sure, it's still not ideal, but I honestly don't think there's a problem using it.
But if I'm wrong, of course I'll gladly dump it too.
(And yes, this one is legit spring water and not repackaged tap water!)
