Edición en Inglés
Water is essential for life, and CLEAN water is essential for a healthy life. Water can contain both dirt and organic matter that makes it unsafe, but it can also contain heavy metals, toxic chemicals and germs even when it looks clean.
This book is about cleaning water, taking away the most dangerous germs and chemicals that can make you very sick and sometimes can cause death.
Water is unsafe when it contains germs, worms, or toxic chemicals. Germs (tiny living things, too small to see, that cause many kinds of illness) and worms, such as whipworm, hookworm, and roundworm, cause many serious illnesses.
Germs and worms live in human and animal waste (urine and feces) and can cause serious and long-lasting illnesses.
