Chemicals in naturally sparkling water?

[Village]

Hi, recently I've been opting for naturally sparkling water such as Perrier, Ferrarelle, San Pellegrino and so on because it's bottled in glass and comes from a natural source. I tried to figure out if they contaminate the water with fluoride (I know there's fluoride in it, but isn't it the naturally occurring type?) or other chemicals but couldn't find any information.

Would appreciate if any of you know.

These kinds of water vary widely when it comes to their composition and it's mainly influenced by the geology of the area they are sourced from. As you know naturally sparkling waters are rather rare. Some of them, Perrier for example, due to economic demand is no longer 'naturally sparkling' but the water and CO2 are still sourced in the original geological area. 

Not sure what you mean by contamination with fluoride.

Well, I'm mainly interested in the 3 I stated because they are the ones available where I live.

I mean do they dump chemicals into the spring water?

Makes sense, they're quite common. I love San Pellegrino myself.

The norms kept when bootling these waters are rather rigorous and you don't really have to worry about it. 

Fluoride and other ions/minerals found in them are naturally occurring at the source.

@JohnnyAb Great. If so, this is really the best water you can get.

There's a reason why it's used by majority of sommeliers and served in the most prestigious restaurants
