What is a chloramine?
Chloramines are used to disinfect and kill germs in drinking water. Chloramines are most commonly formed when ammonia is added to chlorine to treat your drinking water. Chloramines provide longer-lasting disinfection as water moves through pipes.
1 in 5 Americans uses drinking water treated by chloramines.
Many public water systems (PWS) use chlorine as their primary disinfectant, but many PWSs use chloramines as their secondary disinfectant to meet disinfection byproduct requirements.
There are 4 different types of chloramines:
- Monochloramine: when chloramines are used to disinfect water, monochloramine is the most common form.
- Dichloramine: is produced when treating drinking water, but at much lower levels than monochloramine.
- Trichloramine: typically associated with disinfecting the water used in swimming pools. Can also be produced when treating drinking water, but at much lower levels than monochloramine.
- Organic Chloramines: are produced when treating drinking water, but at much lower levels than monochloramine.
Are chloramines safe to drink?
The EPA requires water utilities to meet strict health standards when using chloramines in water. The EPA’s regulation of chloramines is based on the average concentration of chloramines found in a water system over time.
The EPA regulates certain chemicals formed when chloramines react with natural organic matter in water.
Water that contains chloramines and meets EPA regulatory standards is safe to use for:
- Other household uses
Current studies indicate that using or drinking water with small amounts of chloramines is not harmful to your health.
Up to 4 milligrams per liter (or 4 parts per million) of chloramines in drinking water are considered safe.
Harmful Effects of Chloramines
While small amounts of chloramines are not harmful to most, they do pose a risk to hemodialysis patients and fish. For more information, we recommend reading the Water Quality Association’s (WQA) Fact Sheet on Chloramines.
