some of you on this thread might find this youtube video/documentary on bottled water interesting.
The Story of Bottled Water
It gives a new look at our assumptions about bottled water, though I know there are companies out there that do a good job. One of the best, which I drank for years when very sick and concerned about what I put in my bod, is Volvic - but it's from France! The video also give statistics on city water - better than you think.
We drink our well water, which is filtered with two types of filters and run through a UV light
. It is high in minerals, which may or may not be good for us, but it's what we have. We try to take a lot with us in high grade plastic water containers when traveling, and reserve it for drinking, using campground water for everything else. Many campgrounds, due to location, are on wells and likely have some filtration system similar to what we have at home, or use a chlorination system. But who knows? I've always figured taste is the tell-tale sign of good water, I use to haul water from a local park, a source of water for many locals, before we had a well, and though it smelled sometimes of sulfur at the source, it tasted wonderful and tested good.
