I saw a guy on the local news last night who was promoting raw water (total hipster douche). He goes out and finds streams in the wild and drinks from them. His criteria as to whether or not to drink from it seemed to be mostly based on how picturesque the stream and surrounding woods were. Something about a lack of impurities found in "industrialized" water. Coincidentally he was also running a business of selling his stream water to hipster techies in SF for 10$ a gallon.
