By natural I mean water that has not entered the grid, been treated at facilities, came from the tap, been bottled, etc.
I made it through the Nevada desert by doing so. Salt Lake City had more water then I could have dreamed of. Snow runoff rivers were everywhere and their is a natural Artesian Well right in town.

Biking is already a super green way of traveling yes but their are many more ways to be better to the planet.
