ABSTRACT
Historically, waterborne disease was one of the great problems of all societies, and had a profound effect on life and health within communities. The advances made in water treatment and disinfecting of water supplies helped our society, especially the young, since they were typically most affected. Globally, today 88% of diarrhea cases are linked to unsafe water or poor hygiene techniques. This results in 1.5 million deaths each year, mostly in young children. (See endnote 1, Chapter 3; 40.)
