Of course it's possible, all they mean is that the water was in the aquifer for 5000 years, which there's no reason why it wouldn't be there for that long. However, even water in aquifers can get polluted. Also there's no reason water wouldn't travel miles in aquifers. Also water is often forced out of aquifers under pressure for centuries.
Water in aquifers, depending on the aquifer also has more of certain kinds of minerals, that being said, I doubt that makes water superior to the purified stuff.
The water that tastes best to me is purified water. Most brands will do. Cheapest is best. Mine comes out to about 7.5 cents per 500ml bottle from either Costco or Sam's.
The best tasting water I've ever had was in a spring up in Greece. Something about the minerals in it. Spring water in Greece tastes awesome, but I'm not talking about the bottled stuff.
The bottled spring water in Florida it just tastes awful to me. Also the tap water. The tap water in Florida has high levels of Chloramines, which tastes worse then water chlorinated the normal way done in Greece. It also kinda smells bad. It also has a little bit of lead in it, but not too much, yet lead fucks you over in any amount, just to a lesser extent I think.
yep just h2o and nothing else is water.
No product from the ground is just water. it is water and chemicals. minerals etc.
the problem with all water not sold as purified is you have no idea what is in it since it is either added minerals or natural minerals.
if you buy purified water there are simple tests.
see if it supports electrolysis pure water does not short out electricity.
see if it leaves residues if boiled away in a pot on the stove.
pure water will leave zip nada nothing.
some purified water will leave a very small amount of black carbon since it may or may not have passed through a carbon filter to improve taste.
i am all for drinking various things but if i am drinking water i drink reverse osmosis then distilled in my still.
this water has zip nada nothing in it and you can drop a 120 volt extension cord into it with no shorting.
i found this out by accident.
almost no bottled water other then purified nothing added water does this.
