What’s the difference between most bottled water that you buy and tap water? Gina Shaw says not much:
In a lot of cases, bottled water is just tap water. The EWG [Environmental Working Group] report found that at least two distributors (Wal-Mart and Sam’s Club) were basically bottling and selling tap water, while many other major brands, including Dasani and Aquafina, distill or purify tap water for their product. If your bottle doesn’t say “spring water” on it, chances are the water came from a municipal water source.
In most cases, you really don’t need to buy bottled water. Municipal tap water is almost always safe to drink, experts say.
Fewer that one quarter of water bottles are recycled in the U.S., according to the article. That alone is one good reason for drinking from the spigot.
