Humans can only survive three days without water, and most of the world's water is not safe for drinking.

What happens when a person's water supply is in danger? This frightening question is a real concern for backpackers who venture into territories with unstable water access, and increasingly even for everyday folks, given the rising rates of water insecurity and the threat of natural disasters.

With Vogel's scientifically informed but practical and easy-to-understand handbook, readers do not need to fear the dangers of a water-deprived situation. The book contains critical life-saving advice on how to find, assess, treat, and store safe drinking water in the most extreme places; ranging from hurricane-ravaged cities to remote desserts - a handbook to soothe everyone's water-related anxieties.
