Scientists have identified a chemical that has been noticed in American tap water samples since the 1980s – chloronitramide anion. This chemical, found in water systems serving about 113 million Americans, comes from chloramine, a common water disinfectant used to kill harmful bacteria. After decades of detective work, researchers from the University of Arkansas and their international collaborators finally pinned down this elusive compound. While its presence isn’t cause for immediate alarm, scientists want to study its potential health effects quickly. “We need to investigate it. We don’t know the toxicity,” says Julian Fairey, environmental engineer and associate professor at … Continue reading Chemical in U.S. Water: Chloronitramide Identified in 40 Samples Across 10 Cities After 40 Years
