Does Chlorine in Tap Water Cause Cancer?

Hey Sam, I have heard through various sources that the chlorine in tap water can contribute to (or cause) cancer. Is this true or not? Thanks, Chad

Hey Chad. Some studies have shown a link to cancer but not always. Most of the large scale research seems to indicate that there may be a small increase in the rates of bladder cancer, especially in men.

However, many public health agencies, such as the WHO say that the existing studies are not sufficient to draw any conclusions and that chlorinated water is obviously much better for you than, say, nonchlorinated water.

The EPA also sets maximum levels for chlorine in tap water. Most cities in the United States fall far below the maximum levels.

Overall, some studies show a slighter risk associated with chlorine in the water, but the findings are not conclusive.
