The Problem with Chlorinated Water

The Problem with Chlorinated Water

“Chlorine is used almost universally in the treatment of public drinking water because of its toxic effect on harmful bacteria and other waterborne, disease-causing organisms. But there is a growing body of scientific evidence that shows that chlorine in drinking water may actually pose greater long term dangers than those for which it was used to eliminate.”

Francis T. Mayo, Director, Municipal Environmental Research Laboratory

Tap water may be quick, easy, and convenient, but there is good reason to reconsider it in the light of new scientific research. Chlorine has been used since the late 1800s to disinfect water. It is now standard water treatment in many places. Chlorine is used mainly because it is cheap and very effective in eliminating water borne infections that are common in developing countries. Its safety however has increasingly been brought into question

Disinfection By-Products (DBPs)

Chlorine itself is harmless. However, some research reveals that the DBPs produced from chlorine can potentially cause toxic effects. Some very dangerous DBPs created from chlorination of water are trihalomethanes (THMs), volatile organic compounds (VOCs), and Haloaecetic Acid (HAAs):


  • Can cause cancer, according to several animal studies.
  • Trigger production of free radicals in the body.


  • Can lead to drowsiness and central nervous system depression.
  • Can irritate skin and mucous membranes.


  • Are a probable human carcinogen.
  • At high levels can cause liver disease according to animal studies.

What About Showering?

This may come as a shock to you: chlorinated water is dangerous even when used for bathing! Research shows that your body can absorb much more chlorinated water when showering than when you drink water. This can increase your risk of developing bladder and rectal cancer.

“Cancer risk among people drinking chlorinated water is 93% higher than among those whose water does not contain chlorine.”

Dr. J.M. Price, Saginaw Hospital, Author of ‘Coronaries Cholesterol Chlorine’

Conclusion: There are good reasons to think that chlorinated water is simply not safe!
