A New Chemical Identified in Drinking Water Could Be Toxic!
A recent study in the journal Science has identified a potentially harmful chemical byproduct present in about a third of U.S. homes. While the byproduct is still being studied, scientists are investigating its potential dangers and health effects. Due to its similarities to other concerning chemicals, it is suspected to have toxic properties.
The New Chemical Identified in Drinking Water
Chloronitramide anion is the new chemical identified in drinking water. Although it was first discovered about 40 years ago, researchers have only recently determined its chemical structure using advanced analysis techniques. Chloronitramide anion is formed when water is treated with chloramine, a disinfectant created by mixing chlorine and ammonia. This treatment is commonly used in municipal water systems to kill viruses and bacteria.
According to researcher Michael A. Funk, “This anion was detected in 40 drinking water samples from 10 U.S. water systems using chloramines.” This suggests a high likelihood of the chemical being present in your home’s water. He further explained, “It’s a pretty small molecule, and for that reason, it can probably enter biological systems and cells. And it is still a reactive molecule—those are the kinds of things you worry about.”
To clarify, small, reactive chemicals can pose a significant threat even in minimal quantities because they can undergo rapid, uncontrolled chemical reactions within the body. Due to limited conclusive evidence, chloronitramide anion's effects on human health remain unpredictable, but ongoing studies aim to provide more clarity. Unfortunately, regulatory action based on these findings could take years to implement.
How to Address This Concern
For effective removal, a mixed treatment process—such as combining catalytic carbon filtration with ion exchange or reverse osmosis—may be necessary. Catalytic carbon is particularly effective at removing chloramine from water, reducing the likelihood of forming chloronitramide anion. We have several systems which utilize catalytic carbon such as our:
