Ugh my roommate buys this all the time in subscriptions and not only is it unfiltered (or barely filtered) tap water with some crap flavoring, but all the water they're getting is being pumped from California underground lakes and taking up the biggest percentage of our water usage when it's actually accounted for. Boycot this company. Tap water is required to be filtered more times than bottled is, and if you're worried about your local tap water you're better off to find a spring in your area and buy directly from them. Cheaper and more eco-friendly. Or...or....a filter for your tap!
