Not sure how a bottle of Waiakea water, bottled on the Big Island of Hawaii, ended up in a Circle K gas station in rural Indiana, but that’s where I tried a nice cold bottle of it for the first time (I can’t even recall drinking this when I visited Kauai last summer).
A lot of times a water doesn’t live up to the hype: You expect it to be really good, and it falls short, or it has some fancy story but is pretty underwhelming. The opposite happened to me with Waiakea water. I absolutely loved this water for its high pH of 8.8 and for its soft mouthfeel, thanks to a high presence of silica (which seems to be found in these “volcanic” waters), only to find out that it’s essentially Hawaiian municipal tap water run through charcoal filters. Oh well…Hawaiian municipal tap water must just taste damn good!

Total Dissolved Solids: 110 mg/l
pH: 8.2 – 8.8 (alkaline)
Tough to find a specific TDS breakdown, which is a little odd. Several articles seem to suggest its TDS levels of 110 mg/l come mostly from silica, calcium, and magnesium, in that order.
