All water for cities and communities must be sanitized; even waters that come from
clean sources, protected watersheds, reservoirs, and deep wells, are commonly sanitized
to assure safety. Chlorine is the most commonly used sanitizer for several reasons: it is
eff ective against a wide range of microorganisms, the cost is low, and the methods of
applying it have been well developed. If an adequate concentration of chlorine is present
in the water for a few minutes, disease producing bacteria will be destroyed. A number
of conditions aff ect the sanitizing action of chlorine. In municipal systems these can be
controlled so that if chlorine is detectable, it can be assumed that bacteria have been
killed. The factors that infl uence the rate of kill are temperature, pH, presence of other
materials that react with chlorine, time, and the concentrations of the various chlorine
combinations that are formed in the water with ammonia and other substances that react
with chlorine.
