How to treat chlorinated water?
Our recommended approach to treating chlorinated water is filtration. By running the water through a filter with activated charcoal in granular or particle form, you can significantly reduce the chlorine and chloramine contents in your water, as well as the general taste and odor associated with chlorine and DBPs.
What is the name of the chemical that is added to pool water?
Instead, liquid chlorine or sodium hypochlorite (NaOCl) is added to the pool water. When either of these forms of chlorine is pumped into the water, it creates hypochlorous acid (HOCl), which is highly active against all bacterial, viral, and fungal human pathogens.
How to find out how much chlorine is in water?
The fastest way to find out is to either request a water quality report from your local municipality or purchase a DIY home water test kit and check your water for chlorine.
Water Treatment with Chlorine and Chloramines
Chlorine and chloramines are added to water during the treatment process to disinfect it. The use of these chemicals, the most common methods for disinfecting drinking water, kills potentially harmful contaminants, such as viruses and bacteria, and protect public health.
EPA Mandates
The U.S. Environmental Protection Agency (EPA) and the Indiana Department of Environmental Management (IDEM) require a minimum level of chlorine and chloramines to be maintained within water as it comes from our treatment facilities to your water tap.
Household Effects of Chlorine and Chloramines
Higher levels of chlorine and chloramines may exist in your tap water if you live close to an Indiana American Water treatment facility. Although you may notice the taste or smell of chlorine in your water, we closely monitor these levels to ensure tap water is always safe to consume.

Lab Effectiveness, Field Effectiveness, and Health Impact
At concentrations that are used for household water treatment programs, the hypochlorite solution is effective at inactivating most bacteria and viruses that cause diarrheal disease. However, it is not effective at inactivating some protozoa, such as Cryptosporidium.
Economics and Scalability
A bottle of hypochlorite solution that treats 1,000 liters of water costs about 10 US cents using refillable bottles and 11-50 US cents using disposable bottles, for a cost of 0.01-0.05 cents per liter treated. Education and community motivation add to program costs.
