No sources beyond pseudo-sciences... according to my first page of googling.

I don't know about adverse effects, but I've always considered the environmental impact of sparkling water. I still don't get why some people are unaccustomed to the taste of just water.

For me it's not so much about being unaccustomed to the taste of pure water, as much as it just looking for variety in life.

AFIAK bubbled water is acidic and it can hurt mucous membranes.
