You may already know that clean water is scarce in many parts of the world. But, did you know that every eight seconds a child dies from problems caused by drinking water that is contaminated and unsafe?

You have found "A Layman's Guide to Clean Water": An introduction to water, sanitation, and hygiene education, development, and technology in terms that are simple and easy to understand.

The purpose of this website is to give an outline of the technologies and methods used in finding, developing, and delivering clean water to those in need around the world.

The inspiration for this website comes from my experiences in Africa and the rainforests of Latin America.
