Water Chlorination
By FACT

A new National Cancer Institute (NCI) study suggests that people who have been drinking chlorinated surface water for 40 or more years have an increased risk of developing bladder cancer.

Chlorinated drinking water offers immense health benefits, killing microorganisms that cause diseases like typhoid, cholera, polio, and hepatitis. Since chlorination began, waterborne diseases have dropped dramatically in the United States.

When chlorine is added to disinfect water, chlorination by-products are formed, resulting from the interaction of chlorine with naturally occurring and man-made organic chemicals in the water.

The researchers, in the current study, found that risk for bladder cancer was affected by the combined influence of years of drinking chlorinated surface water and the amount consumed. Those who drank the largest amounts of this type of water had greatest risk.

It is not clear what compounds in the chlorinated surface water are responsible for the increased bladder cancer risk. Chlorination by-products consist of volatile compounds, which evaporate upon heating, and nonvolatile compounds which are not removed upon heating. In addition to these chlorination by-products, other contaminants may increase risk.

At present, most experts believe that the benefits of chlorination of drinking water outweigh the risks. More study is needed to confirm the role of chlorinated drinking water in the causation of bladder cancer.
