Aprašymas

How to find and prepare safe drinking water--anywhere, any time!

Clean drinking water may be the last thing we think about day to day--but it's the first thing we need in an emergency. Now, survival expert and biologist Joe Vogel explains how to find, treat, and store safe drinking water--even in the most extreme conditions. A Field Guide to Clean Drinking Water includes information about:

• The role of water in the body and how to calculate your water requirement
• Plants, geographical features, and more indicators that signal the presence of water
• How to collect dew and precipitation, and extract water from plants
• How to screen "raw water" for bacteria, pesticides, and other contaminants
• Every purifying method from boiling techniques to chemical disinfection
• And storage options that meet every need.

Small enough to take anywhere--and broad enough to cover everything--this is a vital manual for backpackers, survivalists, and anyone who may need to know how to create their own drinking water.
