Nearly 1 billion people in the world lack access to potable (drinkable) water, mainly those living in third world countries. In these areas, women and children often have to travel to collect clean water. This can even affect the ability of children to go to school.
Often times, people will have to resort to using the only available water, even if it is unclean. This lack of clean water causes a huge problem in underdeveloped areas. Pathogenic microorganisms – such as viruses, bacteria or parasites — are transferred to a person through drinking, washing or bathing with contaminated water or eating foods that have been prepared from unclean water, contaminated by feces. These pathogens often cause diarrhea, which can be fatal when a person becomes dehydrated.
