Despite the identification of a new chemical and the presence of an old chemical, fluoride, in drinking water, experts said most tap water is safe to drink

Scientists discovered a chemical byproduct, chloronitramide anion, in chloraminated tap water across U.S. homes.

For more than four decades, scientists have noticed a mysterious chemical in the treated drinking water of millions of people in the United States, but no one’s been able to pinpoint exactly what it is – until now.

A previously unidentified chemical has been discovered in the tap water of about one-third of U.S. homes, a new study has found, and scientists are actively investigating whether it's toxic.

The recent discovery of a new chemical in drinking water has alarmed scientists after a new study concluded it could potentially be toxic. The new research, published Nov. 21 in the Science journal, examines the potential impact of a previously unidentified chemical byproduct of chloramine

A new study reveals chloronitramide anion, a chemical byproduct of water disinfection with chloramine, in tap water used by 113 million Americans. While its toxicity is unclear, its similarity to toxic compounds raises health concerns.
