This all depends on what tap water and what bottled water you are using.
Bottled water and Tap Water are the same thing. It is treated H2O.
The flavor of your tap water depends on how well it was filtered, what chemical treatments are used in it, and the quality of your pipes.
The flavor of bottled water is determined by its treatment process, whether they added anything to it, and the effects of the bottle.
Spring water is jsut water from a spring. Drinking water or filtered water typically goes through a reverse osmosis filter. Distilled water is distilled into pure H20
Some companies add minerals to help with flavor or to help your body absorb it.
We live in an industrial city and our water is horrible. It is expected that you are going to filter it when it reaches your house. Our shallow well water smells like sulphur. We purchase filtered water for drinking, but plan to get a water softened and filter soon.
Dasani is good tap water, and other bottled waters are typically the same just added filters.
The machine out in front of the grocery store that fills the 5 gallon tanks is just using city water with good filters.
