The addition of chlorine to water offers many advantages. This essential element ensures safe drinking water and helps keep swimming pools free of harmful germs. However, a recent study published in Environmental Health Perspectives has shed light on a concerning aspect: chlorine, while used for water disinfection, can produce byproducts when it reacts with natural organic matter in water (such as leaves and twigs). One of these byproducts, known as trihalomethanes (THMs), has been identified to possess carcinogenic properties, potentially increasing the risk of cancer.
Should We Be Alarmed by These Findings?
It is crucial to understand that THMs are subject to regulations in both the United States and the European Union. In the U.S., the permissible limit for THMs is set at 80 parts per billion (ppb), while the E.U. adheres to a limit of 100 ppb. For context, typical drinking water falls within the range of 40-60 ppb, according to the EPA. Despite these regulations, there are concerns about the adequate enforcement and compliance with these limits. Data from the Environmental Working Group (EWG) reveals that thousands of individuals in the U.S. are exposed to water with THM levels exceeding 200 ppb.
Alarmingly, the study shows that heightened cancer risks can emerge at levels as low as 40 ppb, indicating that everyday drinking water might be posing health risks. According to the EWG, the safe level of THM consumption should not exceed 0.15 ppb. While the adverse effects of THMs on health are not a new revelation, this recent study underscores that these compounds can have detrimental effects at lower concentrations than previously assumed, as explained by Hydroviv’s founder, Eric Roy, Ph.D.
The research also suggests that THMs could elevate the likelihood of developing bladder and colorectal cancer. Analyzing data from approximately 30 studies involving 90,000 participants, the researchers observed a higher risk among men than women.
Dr. Brintha Vasagar notes, “Further research is necessary to identify the most hazardous THM compounds and the threshold levels that impact human health. This study could mark the initial step towards refining the optimal chlorination levels in our public water systems.”
Why Do We Chlorinate Water Despite the Risks?
Dr. Vasagar emphasizes the crucial role of water chlorination in eliminating microorganisms and safeguarding public health. “Although THM levels would decrease significantly without chlorination, the consequences in terms of disease would be catastrophic.” Indeed, the benefits of chlorinating water are immense. The introduction of clean, chlorinated water has been attributed to reducing infant mortality by three-quarters and child mortality by nearly two-thirds in the
“There is no one-size-fits-all approach when it comes to water safety,” explains the expert. “While some individuals may consume unfiltered tap water without issue, others may experience adverse health effects over time.” How to Safeguard Your Health: To purify your drinking water, there are several effective methods available. Vasagar suggests boiling water or utilizing carbon filtration or reverse osmosis systems, which pass water through a semi-permeable membrane for double filtration. “Boiling water is cost-effective but time-consuming, carbon filtration strikes a good balance between purity and affordability, and reverse osmosis guarantees the purest water but comes at a higher cost,” she advises. Additionally, she advises individuals at a higher risk for bladder or colorectal cancer to consider using these filtration systems. “Early detection is crucial, so ensure you visit your family doctor yearly, or sooner if you experience unusual symptoms such as blood in stool or urine, unexplained weight loss, or persistent malaise,” she recommends.
