General Assembly of the United Nations (UN) recognized access to clean water and sanitation as a human right alongside other fundamental rights, such as life and liberty, freedom of expression, and education.According to the UN:“Lack of access to safe, sufficient, and affordable water, sanitation, and hygiene facilities has a devastating effect on the health, dignity, and prosperity of billions of people and has significant consequences for the realization of other human rights.”Untreated water contains pathogens such as the bacteria that cause diarrhea and the parasitic worms that cause schistosomiasis (snail fever).These pathogens spread far and wide when untreated human waste contaminates groundwater and open water that people use for.
