7. Pricey Tap Water
As much as 40 percent of bottled water sold in the United States is likely to be simple tap water. Tap water costs significantly less than 1 cent per gallon on average, so how foolish does it seem to be buying bottled tap water for 5 cents per gallon? Check bottled water labels for things such as “from a municipal source” or “community water system,” which translates to “this is just tap water in a pretty bottle.”
