As we age, we become more mindful of our health—making smart food choices, staying active, and keeping up with medications.
But what if something as simple as the water we drink every day could be affecting our well-being in ways we never considered?
A new study from Sweden has brought attention to a chemical commonly found in water, raising serious concerns about its potential link to cancer.
While clean drinking water is essential, it’s important to understand what’s really in it and how it could impact your health.
Knowing what to look out for can help you make informed decisions about your water consumption.
Taking small steps to protect yourself now could make a big difference in the long run.

A study conducted by researchers at the Karolinska Institute has identified trihalomethanes (THMs) as a possible health concern.
These chemicals form as byproducts of the chlorine disinfection process used in nearly all public water systems across the United States and the European Union.
THMs consist of four compounds: chloroform, bromodichloromethane, dibromochloromethane, and bromoform.
The research suggests that long-term exposure to THMs may increase the risk of bladder cancer by up to 33% and colorectal cancer by 15%.
For millions of Americans—especially those over 60—this finding highlights a potential risk that’s worth understanding and addressing.
Chlorination has been a cornerstone of public health since it was first introduced in Jersey City, NJ, in 1908. It played a crucial role in reducing waterborne diseases like cholera and typhoid fever, making drinking water safer for generations.
However, in the 1970s, scientists discovered that chlorine interacts with organic matter in water, creating byproducts like THMs and haloacetic acids (HAAs).
While chlorination remains vital for preventing bacterial contamination, the long-term effects of these chemical byproducts raise new concerns.

Lead researcher Emilie Helte emphasizes the need for further studies to fully understand the impact of THMs on human health.
The challenge lies in maintaining the benefits of water disinfection while minimizing the risks associated with these byproducts.
One possible solution is upgrading water treatment systems with advanced filtration technologies. However, such improvements would require significant investments.
In the meantime, being informed and taking personal precautions can help reduce exposure to potentially harmful substances in tap water.
While addressing THMs on a larger scale will require action from public health officials and water providers, there are steps you can take right now to minimize your risk:

What Can You Do to Protect Yourself?
While addressing THMs on a larger scale will require action from public health officials and water providers, there are steps you can take right now to minimize your risk:
- Use a Home Water Filter – A granular activated carbon (GAC) filter can effectively reduce THMs and other contaminants in your drinking water. Look for filters that are certified to remove these chemicals.
- Stay Informed – Check your local water quality reports. Many municipal water systems publish annual reports detailing contaminant levels, including THMs.
- Advocate for Safer Water – Contact local representatives and water authorities to express concerns about water treatment practices and encourage investment in better filtration systems.
- Diversify Your Water Sources – If you're concerned about your tap water, consider alternating between filtered tap water and bottled water from a trusted source. However, keep in mind the environmental impact of plastic waste.
- Boil Your Water – While boiling water won’t completely eliminate THMs, it may help reduce their concentration. This can be a short-term solution while you explore more effective filtration methods.

Key Takeaways
- Disinfecting water with chlorine, a common practice in the U.S., produces chemical byproducts that have been linked to an increased risk of bladder and colorectal cancer.
- Trihalomethanes (THMs) are the chemical compounds in chlorinated water that raise particular concern due to their potential carcinogenic effects.
- Researchers suggest that more high-quality studies are needed to fully understand the risks but caution against reducing the amount of disinfectant used in water.
- While addressing the issue at a public health level may be costly, individuals can use granular activated carbon filters to reduce their exposure to these harmful chemicals in tap water.
