Why Does My Tap Water Smell Like Chlorine?

Your nose isn’t playing tricks on you. There’s a good chance that the chlorine smell in your water is chlorine. And it probably got in your water because your local water treatment plant put it there.

Wait, so the people in charge of keeping our tap water safe are also making it smelly?

Yes, and for a good reason.

Municipal water treatment plants use chlorine to treat drinking water because it effectively kills the bacteria that cause many waterborne illnesses. Before we started using chlorine to treat our water, deaths from contracting diseases like cholera and typhoid from drinking water were extremely high. But chlorine has helped to curb those illnesses significantly.

Therefore, the presence of some chlorine in your drinking water is a good thing. The Environmental Protection Agency (EPA) requires chlorination but limits the amount allowed in drinking water to 4 mg/L.

However, all it takes is 1 mg/L of chlorine for you to start noticing that smell in your glass. And, as we’ll see, ingesting too much chlorine over time can lead to significant health problems.

Chloramine is another common disinfectant that can give off that bleach smell. Water treatment facilities often use chloramine as a secondary disinfectant to help the water treatment last longer.

The Potential Health Risks

Because they are such common disinfectants, some chlorine and chloramine are usually present in drinking water. And it is generally safe to consume the disinfectants in small doses.

So, is it safe to drink tap water that smells like chlorine? Not necessarily.

When your water starts smelling like a pool, it’s a warning sign that your water could be overchlorinated. And anything over the EPA recommended limit of 4 mg/L and even slightly under it could lead to serious health problems.

Health issues associated with consuming too much chlorine include bladder, rectal and breast cancer. Overconsumption of chloramine can also cause digestive problems, respiratory issues and mouth ulcers. On top of this, the disinfectants can also dry out your skin and hair after bathing and corrode household plumbing fixtures over time.

Chlorine and chloramine can also create harmful byproducts during the disinfection process. These byproducts include trihalomethanes (THMs) and haloacetic acids (HAAs). Consuming THMs can lead to cancer and congenital disabilities, and HAAs can cause cancer, liver and kidney problems.


How to Get Rid of That Pool Smell and Taste

There are a few different ways to deal with tap water that smells like chlorine. The method you should choose depends on the severity of the problem.

Therefore, before you do anything, we recommend getting your water tested to determine how much chlorine is in your water.

Hopefully, the test results will reveal that the amount of chlorine in your water is below the EPA recommended limit of 4 mg/L. If your water exceeds that limit, you should report the results to your local water utility right away so that they can address the problem.

But don’t wait around for the government to fix the problem on their end. After all, you can take steps to eliminate the harmful contaminants from your water.

The best way to get rid of chlorine, chloramine, TTHMs and HAAs is by investing in a dependable water filter for your home. A carbon-activated filtration system or reverse osmosis system should do the trick.

Of course, the water test could also reveal that your water doesn’t contain dangerous amounts of chlorine and chloramine. If this is the case, you don’t necessarily have to invest in a water filtration system to eliminate the chlorine smell and taste.

Alternative home remedies exist to remove the stench without getting rid of the disinfectants. For example, you could chill the water in a covered pitcher for a few hours to give the smell a chance to dissipate naturally. Other potential remedies include boiling the water or adding dichlorination tablets.

While these alternative methods may save you money, they aren’t guaranteed to eliminate the odor like a water filtration system will. Because of this, we feel a water filter is the best solution for long-term success and convenience.
