Water has many uses, including drinking, recreation, sanitation, hygiene and industry. Water can be considered our most precious global resource. Having clean and safe drinking water is critical to human life and without it waterborne illness can be a serious problem.
Waterborne illnesses are caused by various bacteria, viruses and pathogenic microorganisms and usually occur as a result of poorly treated drinking water and wastewater or a natural disaster.
Unsafe drinking water, inadequate availability of water for hygiene, and lack of access to sanitation together contribute to about 88% of deaths from diarrheal diseases. (CDC)
