Common Water Disinfectant Creates Potentially Toxic Byproduct: What You Need to Know for 2025

Washington D.C., November 2024. A groundbreaking study published in the journal Science has revealed a concerning new risk in the U.S. water supply. Researchers have identified a previously unclassified byproduct of water disinfection called “chloronitramide,” a compound formed during the use of inorganic chloramines. This byproduct has been detected in public water systems at levels exceeding regulatory safety thresholds, potentially affecting millions of Americans.

Chloramines, often used as a disinfectant alternative to chlorine, were introduced to reduce certain harmful byproducts linked to the latter. However, this new discovery raises urgent questions about their long-term safety and the need for more effective water treatment practices. As 2025 approaches, ensuring access to clean and safe drinking water is more critical than ever.

The Hidden Dangers of Chloramines

Chloramines have been a key part of water treatment systems in the U.S. for decades, providing an alternative to chlorine to reduce byproducts linked to bladder and colon cancer. They are currently used in water supplies serving over 113 million Americans. However, the study reveals that chloramines break down into previously unidentified compounds, including chloronitramide, which was found in all 40 water samples tested by researchers.

Chloronitramide concentrations reached up to 100 micrograms per liter—far above the allowable limits for disinfection byproducts, which range from 60 to 80 micrograms per liter. Although the health effects of this compound are still under investigation, researchers have expressed concern about its chemical structure and potential toxicity.

Dr. Julian Fairey, the study’s lead author, stated: “The presence of chloronitramide in drinking water warrants immediate toxicological studies. Its chemical structure and the concentrations at which it appears are highly concerning.”

Implications for Public Health

This discovery adds to the growing challenges facing water quality in the United States, already under scrutiny due to contaminants like PFAS (“forever chemicals”) and lead. The potential health risks associated with chloronitramide include:

• Unknown effects on long-term health, requiring further research.
• Possible links to cancer and other chronic conditions, similar to risks posed by other disinfection byproducts.
• Increased exposure risk in communities with outdated water infrastructure or insufficient treatment facilities.

Given the widespread use of chloramines in water systems across the U.S., the findings highlight the need for immediate action at both the regulatory and household levels.

What Can Households Do?

For families concerned about their water quality, experts recommend proactive measures to reduce exposure to harmful contaminants. Advanced home filtration systems can effectively remove chloronitramide and other disinfection byproducts. Here are some recommended solutions:

• Activated Carbon Systems: These systems are highly effective at absorbing chemical contaminants. The PURA PACIFICO countertop system and the PURA MINI portable solution offer compact, efficient options for daily use.
• Reverse Osmosis Filtration: This technology provides a thorough purification process that removes even the smallest particles. The PURA OiBASE is an excellent choice for families in areas with high contamination risks.
• Whole-House Solutions: For comprehensive protection, the PURA BIG series offers filtration systems that safeguard every tap in your home, ensuring clean water for drinking, bathing, and cooking.
• Portable Options: For clean water on the go, PURA’s water bottles with built-in purifiers combine convenience and safety, perfect for busy families.

Looking Ahead: Recommendations for 2025

The findings of this study highlight the need for systemic changes in water treatment practices. As we move into 2025, here are key recommendations for families, communities, and policymakers:

• Advocate for regulatory updates: Push for stricter safety standards and testing requirements for all disinfection byproducts, including chloronitramide.
• Upgrade water treatment infrastructure: Encourage investments in advanced treatment technologies at the municipal level to reduce reliance on chloramines and other outdated methods.
• Adopt sustainable practices: At home, prioritize solutions like reusable water bottles and filtration systems to minimize environmental impact and reduce reliance on single-use plastics.
• Stay informed: Regularly check your local water quality reports and stay updated on emerging research to make informed decisions for your family’s health.

A Call to Action

As the EPA and other agencies evaluate the implications of this study, households can take immediate steps to safeguard their drinking water. Choosing a reliable filtration system is a simple yet powerful way to protect your family and support sustainable practices.
