I've read that Disneyland uses reclaimed, purified water for their plumbing and water fountain needs. I have noticed, however, that whenever I'm thirsty at Disneyland, the water from the water fountains just won't quench my thirst. I can drink until my stomach hurts BUT I'm still thirsty. The bottled waters quench my thirst but the fountains don't. Why??? Has the water been TOO purified?
