Ammonia occurs naturally due to organic degradation and is commonly found in groundwater. Ammonia’s influence on water treatment is that it reacts with chlorine disinfectants, interferes with iron and manganese oxidation and can significantly increase disinfection and oxidation doses of chlorine. In distribution systems and in some treatment facilities, it can cause objectionable tastes and odors. Ammonia also has a tendency to accelerate corrosion in copper plumbing and cooling systems.

When chlorine is added to water containing ammonia, a family of related compounds are formed, which can be controlled and used as part of a disinfection program. The compounds are chloramines, and the process is termed chloramination. The benefits of chloramination are fewer disinfection by-products are created in the presence of naturally occurring dissolved organics (THMs and HAAs). One disadvantage of chloramination can be the potential degradation of the chloramine compounds in the distribution system causing objectionable tastes and odors.
