Introduction
"Just because water is clear, smells good, and tastes good does not mean that it is safe to drink. Western nations, like the United States, have systems to purify, store, and distribute water. These systems protect us from many waterborne diseases. However waterborne diseases and parasites continue to plague most of the population of this planet, particularly in the third world. In typical disaster situations, modern systems for purifying and distributing clean water often fail. In these situations, to protect your health, you must purify your own water." (Stein, 2008)
