A while back I watched Tapped, which is a documentary detailing the regulations that are enforced upon municipal tap water and, conversely, the complete lack of regulations surrounding bottled water. It also goes into some discussion of the chemical residue from the plastics the water is stored in, but the overall thrust was enough to convince me to research the claims on my own. Once I did, I found out some interesting things. For example, I found out that water for the bay area comes from glacier runoff from Yosemite, which, unfiltered, is typically cleaner than filtered water.

Anyhow, all of this convinced me to go back to getting my 3 gallons of drinking water each day from the tap. If you are a big bottled water drinker, you owe it to yourself to at least check the facts and see which is actually healthier for you.
