New research identifies link between drinking water disinfection byproducts and risk of colorectal cancer in men

Results from a large population-based cohort study including 60,000 men and women in central Sweden suggest that exposure to higher concentrations of disinfection byproducts in drinking water is associated with elevated risk of colorectal cancer in men.

Drinking water is a very important part of our diet that is consumed daily by essentially everyone in the population. Hence, assuring a that the public drinking water maintains a high standard is crucial. Chlorination of drinking water is a cheap and effective method widely used to control waterborne infectious disease. A drawback is, however, that reactive chemical byproducts can be formed in the drinking water, some of which have been proposed to cause cancer.

Trihalomethanes are the disinfection byproducts that are formed at the highest concentration in chlorinated drinking water. Several of these substances can damage DNA and cause tumors in the colon of rodents. Studies in humans are limited but some indications that trihalomethane exposure increases the risk of bladder and colorectal cancer exist.

In the study, 60,000 middle-age and elderly men and women with varying levels of disinfection byproducts in drinking water were followed for 22 years.

The results suggest that men with the highest exposure have a 20% increased risk of colorectal cancer overall and 60% increased risk of left sided colon cancer compared to unexposed men. In women no overall association was observed. Because many Swedish drinking water producers only use small amounts of chlorine in their production, these findings were observed at lower trihalomethane concentrations than in most previous research studies.

Together with the evidence from animal studies and previous epidemiological studies, the findings of this new study adds disinfection byproducts to the list of other possible environmental risk factors. Given that more efficient and chemical free disinfection methods exist today, exposure is preventable.

There are two main chlorination approaches used in municipal water systems today. One is chlorine and the other is chloramine. Chlorine is easy to filter out. Chloramine is not. The byproducts of both are also not as easy to filter, and as I recall, chloramine is a byproduct of chlorine hitting something it disinfects (would have to check). To really minimize these, you need a catalytic carbon filter, reverse osmosis, or a KDF 85 filter. There are other approaches, though. Activated carbon typically does not typically do a good job on these non-chlorine substances.

Also, these chloramine and other byproducts typically need to have more time to interact with the filter media, meaning you need a bigger filter to handle your whole house at a normal pressure flow rate.

Chloramine lasts a long time in our water, but is supposed to kill germs a long time. Chlorine can dissipate in hours, if the water is left out on your counter.

Interesting stuff, and, yes, it appears these byproducts do cause cancer issues.

So, a minuscule risk of cancer is more frightening than a 100% chance of constant dysentery. Got it.

You can prevent both.

It’s not “either/or.”

This is the best I've found:

Matrikx Chloraguard:

The part numbers are in the table. Look to the flow rate to determine which you may need, or simply restrict the flow to match what can be filtered.

Fluoridated water is a Communist conspiracy. They’re trying to rob us of our precious bodily fluids. I only drink pure grain alcohol and rain water. Purity of essence.

Exactly.

To be safe, I’m going to only drink from puddles on the sidewalk like my dog.

The water filters for my frig water dispenser started a year or two ago being rated as to filtering chloramine. Of course they are $50 & should be changed twice a year.

...In women no overall association was observed...

Then maybe it's not the chloramine...

Evaporation of water may not get rid of all dissolved stuff....nowadays may even need to check rainwater (IMHO)

risk of colorectal cancer in men...

This is SERIESLY SCARY.

So, I should be able to cancel this risk completely, if I just change to being a woman.

A home RO filter should remove Chlorine and byproducts from water.

Looks like none of us are going to avoid death.
Just a matter of how and when.
