We often take safe drinking water for granted. Water from rivers, streams, ponds, or rainwater may be the only sources of water for rural villages in Guatemala. The water may be murky, with an unpleasant odor and taste, and it could be a source of disease, since 60% of all diseases are water-borne. Even clear and apparently fresh water may be polluted with microscopic disease-causing pathogens, and children are especially vulnerable.
