Have been buying 'Select' Sparkling Mineral water, as well as purified water, for years' now, & really enjoy both, freezing cold.
Don't have a problem with tap water, though. My choice.
Remember as a kid, we'd house at Palm Beach, & water tasted 'strange'. Mum used to boil it, then put it into fridge to cool. That did taste better. That was in the '50's, so one would hope the tap water is better now! Haven't stay on the Coast for about 30 years' now!
