There's actually a new hipster fad in the SF Bay area of drinking "raw water", literally just water that's bottled directly from the spring without going through any kind of filtration or testing first. According to San Francisco, the advantage is that it's not treated with chemicals and it has "thousands of natural probiotics" that improve your immune system. You can tell the difference between "raw water" and "corporate water" by the fact that "raw water" has an expiration date and will turn green and grow visible cultures if you don't touch the bottle for a month. And the hipsters no shit pay $35 for 3 gallons of the stuff.
Seriously, watch the video and try not to cringe:
