I mean I know what it is. In general, out in the wilderness, it's stagnant water that isn't drinkable.
I am road tripping through Ireland and noticed brands like River Rock sell bottled still water. I tried it and to me it tastes gross. I noticed on the package that once opened, you have to refrigerate and consume in 3 days. So strange that a type of water that's not sparkling would go bad...I'm baffled lol. I Googled to see what it is and I can't find an answer.
I like mineral water which I've seen in some places, but the town I'm in now has sparkling, still and mineral still. No just regular filtered water? Y'all just drink tap? I'm fine with that, just where I come from, the tap water is not safe to drink.
Halp. I need water. :P
