Scientists Identify Long-Elusive Chemical in U.S. Tap Water

The newly defined chloronitramide anion, found in water treated with chloramine, raises questions about its potential toxicity and public health impact.

Chloronitramide anion, a byproduct of chloramine used in water disinfection, has been identified after decades of research.
The compound was detected in all 40 samples from 10 U.S. water systems serving over 113 million people.
Its toxicity is currently unknown, but its similarity to other toxic molecules has prompted calls for further study.
The discovery allows for new toxicological evaluations and may lead to better understanding and control of harmful byproducts in treated water.
Experts recommend using activated carbon filters for those concerned, though tap water remains safe to drink according to current standards.
