With the ever increasing cases of waterborne pathogens, the government was forced to add chlorine into water with the goal of purifying it. For the last 100 years, we have thus relied on chlorine to ensure we’re receiving adequate and healthy quality water.

Although chlorine has become the standard, it’s important to realise the full ramifications and implications related to chlorine – this article we explore the good, the bad, and the ugly.


The Good

For the most part, chlorine has done an adequate job at eliminating most disease causing microorganisms that often invade our water supplies. For example, the use of chlorine has eliminated various water diseases such as cholera, salmonella, and many others.


The Bad

Chlorine, however, cannot absolutely ensure that your water is one hundred percent free of every unhealthy microorganism – meaning dangerous bacteria can still be found in chlorinated tap water, from e-coli to coliform.

Depending on chlorine therefore doesn’t entirely ensure that your tap water is safe to drink because even the slightest exposure to microorganisms can lead to catching the flu, diarrhoea, cramps, nausea, and vomiting.


The Ugly

There have been countless studies investigating the impact chlorine has on water – the most shocking and surprising of which are included below:

According to the U.S. Council of Environmental Quality: “Cancer risk among people using chlorinated water is as much as 93 percent higher than among those whose water does not contain chlorine.”

According to the BreastCancerFund: “One common factor among women with breast cancer is that they all have 50 to 60 percent higher levels of these chlorination by-products (THMs) in their fat tissue than women without breast cancer.”

According to the National Cancer Institute: “Long-term drinking of chlorinated water appears to increase a person’s risk of developing bladder cancer as much as 80 percent.”

According to Health Freedom News: “The drinking of chlorinated water has finally been officially linked to an increased incidence of colon cancer. An epidemiologist at Oak Ridge Associated Universities completed a study of colon cancer victims and non-cancer patients and concluded that the drinking of chlorinated water for 15 years or more was conducive to a high rate of colon cancer.”



Chlorine was added to drinking water with the purpose of purifying our water – although the initiative was effective at first, it seems as if there’s serious complications and dangers involved with drinking chlorinated tap water. Countless studies have indicated a strong positive relationship because chlorine in drinking water and an increase in cancer and heart disease.

It is therefore highly recommended that you use filters for your tap water to adequately filter unhealthy micro-organisms. In addition, schools and workplaces should also invest in cool water dispensers – doing so will ensure healthier qualities of water for both you and the people you care about.
