New Water Contaminant Found in U.S. Drinking Water

A mysterious byproduct of water disinfectant chloramine has been identified in U.S. drinking water sources.

A breakthrough study has revealed a new chemical contaminant found in drinking water across the United States, shedding light on a decades-old mystery. The substance, identified as chloronitramide anion, is a byproduct of chloramine, a disinfectant commonly used to treat public water supplies. This newly discovered compound is made up of chlorine, nitrogen, and oxygen, and had eluded detection by scientists for over 40 Years.

Chloramines, which is a result of chlorine and ammonia combination, are widely used because they ensure better water quality, hence eliminating harmful microorganisms present in the water, but the chemical reactions that take place during this disinfecting process can possibly produce byproducts like chloronitramide anion, which is not well known. While it has been assumed that similar byproducts are associated with toxicity issues, researchers have not yet established the fact that chloronitramide anion is risky to humankind.

The lead author of the study, Julian Fairey-an associate professor at the University of Arkansas-stresses that much work is still required to accurately assess the safety of this chemical. Still, experts say they are optimistic about chloronitramide anion not posing a major health concern for public safety. Generally, the concentration of contaminant levels in drinking water is regulated for safety purposes, thereby usually keeping the harmful byproducts at subtoxic and low levels.

While the results have led to multiple calls for further study, most researchers and other experts, such as Australian professor of chemistry Oliver Jones, dismiss immediate worry. Instead, says Jones, first order should be understanding what the chemical's precise toxicity might be, and comments that the current levels are surely not hazardous.

An important step forward in advancing the research of water safety is marked with this discovery, promoting continual monitoring and improvement of the water treatment processes to serve the health interest of the public.
