Dunno. Have been unaware of them so far. Am not that often in SJ anyway, but when I am the tap is taboo for me. That stuff can only be spat out.

I know the Eldorado Springs from when I'm in Aspen, Austin, Altadena, and while I don't get the hype surrounding the stuff, it's more than acceptable (for water).

Taste matters. Be it for coffee, tea, cooking, making desserts, even baking, or making your own pizza dough.
