Chlorine • CODE 4-3006-01
Water for cities and communities is usually sanitized. Even waters that come from clean sources, protected
watersheds, reservoirs, and deep wells are commonly sanitized to assure safety. Chlorine is most commonly
used because it is effective against a wide range of microorganisms, its cost is low, and the methods of applying
it have been well developed.
