For example, when a person is vomiting and purging he probably has oneof the diseases caused by bad water.

People dump dead animals, feces and other refuse in these places where we collect our drinking water. Comment l’eau devient-elle sale ? L’eau douce qui sort de terre peut généralement être bue sans danger. L’eau du robinet est aussigénéralement potable parce qu’elle est souvent traitéeen y ajoutant des produits chimiques ou en la filtrant. Cependant dans la plupart
