Chlorination has been used in America's drinking water supply as a defence against waterborne Infectious Diseases for about 90 years. The filtration and chlorination of drinking water are probably the most significant public health advances in history.

one of the earliest uses of chlorine for water disinfection was done by John Snow in 1850, in disinfecting the Broad Street Pump water supply in London after an outbreak of cholera.
