[Star Trek] What kind of water comes from the replicators?

I know you can program different “recipes” into the replicator, but what is dispensed when someone orders water? Specifically, is it just H2O, or are there other chemicals like we would see in city/tap water? I imagine specialty items like Spring Water or Mineral Water would have their own formulas programmed.

It's probably "just" water, with only the minerals and such that can be tolerated by all (or at least the majority) of Federation citizens.

Of course, it's also possible that the replicator knows who's asking, and gives them a glass of whatever they'd get from a very clean river on their homeworld.
