read this book. i should re-read it immediately.
it mentions Stephan Riess. Using this book, and Alick Bartholomew's Hidden Nature, and Living Energies by Callum Coats - you will be able to form a fuller image of what Stephan Riess achieved by drilling deep into rock fissures -- deep in the mountains there is always fresh potable water to be had, even in the desert, if you go down deep enough, you will find fresh, cold, potable drinkable water. The Stephan Riess method should be revived immediately.
