$6 a gallon. That’s not the cost of gas, but the cost per gallon when you buy a 20 oz bottled water at the store. Last year alone, Americans chugged 8 billion gallons of bottled water and that number continues to rise. We’re constantly inundated with hundreds of water choices: artesian water from Fiji, vapor distilled with added electrolytes, spring water from the top of Mt. Shasta, carbon-neutral mineral water from Scotland, and of course good ol’ tap water.

So which is best for me? We’ll examine the safety, health, environmental, and personal factors that go into that choice so we can finally answer: Is bottled water better than tap?
