Our body is 60-80% water; we need water for drinking, cooking, bathing and cleaning. Yet, as important is to all of us, usually we take it very much for granted.

Everytime we turn on a weter lap, we expect water to come flowing. Normally, we take the safety of this water as much for granted as the water itself. This is understandable since most of the world population
is presumably not supplied with safe water.
