Do you taste chlorine in your water?

We’re all familiar with chlorine in the swimming pool, but what does it mean when chlorine is swimming in our drinking water?


Chlorine kills waterborne pathogens

At both the pool and the tap, chlorine is used to treat water against harmful bacteria. According to an essay in Scientific American, “Chlorine effectively kills a large variety of microbial waterborne pathogens, including those that can cause typhoid fever, dysentery, cholera and Legionnaires' disease.”


4 milligrams per liter is safe

Chlorine was introduced as an inexpensive disinfectant for public water in the early 1900s. In the century since, its use has become ubiquitous in the United States. In fact, chlorine is used by over 98 percent of water utilities that disinfect public water. In New York State, for example, Erie Water Works just implemented a twenty-fold increase in the amount of chlorine in the water it serves to the region. The chlorine now stands at .20 milligrams per liter. This is well below the four milligrams per liter the Center for Disease Control outlines as its safety standard.


When chlorine mixes with other chemicals

The benefits of chlorine in fighting waterborne disease can not be understated. However, when chlorine mixes with other chemicals in the water, like fertilizer run-off, it can become an organic compound. As far back as 1980, it has been shown that large amounts of these compounds, called trihalogenated methanes, are linked to cancer in laboratory animals.


Potential cancer risk of organic compounds with chlorine

Fast forward to 2016, and the World Journal of Gastrointestinal Oncology published a study entitled, “Colorectal cancers and chlorinated water.” In academic parlance it stated that “the associated health threats including colorectal cancers colon cancer are dependent on the frequency of exposure to and the levels of trihalomethanes in the water for drinking.” In other words, excessive exposure to chlorine, and/or the presence of organic compounds that include chlorine, could put people’s health at risk.

The poor taste of chlorine in water

There is no reason to suggest that tap water in the United States contains excessive levels of chlorine or the kind of compounds that scientists deem threatening. But many people want to reduce chlorine in their drinking water for a far less menacing reason: they don’t like the way chlorine smells or tastes.


For whatever reason you choose, the Coway Aquamega 100 triple-filtering system reduces chlorine by 99.2%. The purifier installs easily to fit on most kitchen faucets, ensuring the tap water is filtered right before you and your family consume it. All you have to do is enjoy the clean, pure water.
