Water Contaminant Treatments

Chloramine

Drinking Water Sources of Chloramine

Chloramines (also known as secondary disinfection) are drinking water disinfectants used to treat drinking water. They are most commonly formed when ammonia is added to chlorine to treat drinking water.

The benefit of chloramines is that they provide longer-lasting disinfection as the water moves through pipes to consumers. Use by water utilities since the 1930s, more than one in five Americans uses drinking water treated with chloramines.

Treatment of Chloramine

Chloramine levels are more complicated to regulate than chlorine levels. Failure to properly control and monitor the treatment process can cause undesirable chemical reactions such as increased corrosion of pipes or nitrification in the distribution system.

Corrosion can cause leaching of lead and copper from pipes and solder. Nitrification can cause a loss of disinfectant residual. Proper operation and management of the treatment system and disinfectant levels prevents these potential drawbacks to the use of chloramines.

In addition, chloramine will deteriorate natural rubber products like toilet tank "flapper valves" faster than chlorine. Alternative synthetic products are available in plumbing and hardware stores if rubber deterioration becomes a problem.

Chloramines are removed from water sources using specialized filters with functional media to remove chloramines.
