overview
- A recent study has identified a new chemical byproduct that may be present in the tap water of approximately one-third of U.S. households. The potential dangers of this byproduct are still unknown.
- Researchers are currently investigating the toxicity of this newly discovered chemical due to its similarities to other concerning chemicals.
A study revealed that around one-third of U.S. residents are consuming tap water containing a previously unidentified chemical byproduct. Concerns about the potential toxicity of this chemical have led scientists to closely examine it.
The newly identified substance, known as ‘chloronitramid anion’, is created during the water treatment process involving chloramine, which is produced by combining chlorine and ammonia. Chloramines are commonly used in municipal water treatment to eliminate viruses and bacteria.
Although the existence of this byproduct was discovered four decades ago, recent advancements in analytical techniques have now enabled scientists to determine its structure. It has only recently been identified.
While it may take several years to ascertain the potential dangers of the chlornitramide anion, researchers from the study published their findings in the journal Science to prompt further research on its safety.
Researchers noted that there is currently no conclusive evidence indicating that the compound is harmful, but its widespread detection and structural similarities to other concerning chemicals warrant thorough investigation.
Research showed that the chlornitramide anion is a byproduct formed as chloramine deteriorates over time, indicating that it is likely present in all water treated using this method.
The discovery of potentially hazardous byproducts in tap water underscores the importance of understanding the health implications of water treatment chemicals. Further studies are necessary to evaluate the safety of these substances.
Regulations requiring the monitoring and control of disinfectant byproducts are prompting water utilities to shift towards using chloramines over chlorine, as some chlorine byproducts have been linked to health risks.
While conclusive findings on the toxicity of the newly identified chemical may take years, ongoing research aims to minimize public exposure to potential health risks associated with water treatment chemicals.
Many water utilities in the U.S. disclose information on their treatment processes and potential byproducts, suggesting the use of activated carbon filters in household purifiers to remove disinfectant byproducts.
