How Charlotte’s Water Treatment Creates That Pool Smell

Charlotte Water uses a process called chlorination to disinfect water before it leaves the treatment plant. Chlorine is added in a controlled amount to kill bacteria viruses and other pathogens. As water travels through the city’s network of pipes the chlorine slowly breaks down. If your home is far from the treatment plant or if there was a recent water main repair the chlorine may still be active when it reaches you which is why you smell it. EPA Chlorine Emergency Disinfection Guidelines.

During certain times of the year Charlotte Water performs system flushing which temporarily boosts chlorine levels to clean out sediment and biofilms. This is when many homeowners notice the strongest pool-like smell. The flushing usually lasts a few days and is announced in advance. If you are sensitive to the smell you might want to use a filter during these periods.

Another factor is water temperature. Cold water holds dissolved gases including chlorine better than warm water. That is why the smell is often strongest when you first turn on the cold tap in the morning. If you only smell it in hot water the problem might be inside your water heater. The anode rod inside the tank can react with chlorine and create a sulfur or bleach odor. Replacing the rod or flushing the tank can fix this.

Charlotte’s water also contains naturally occurring minerals that can interact with chlorine. For example high levels of organic matter in the source water can create disinfection byproducts like trihalomethanes. While these are regulated by the EPA they can contribute to the overall chemical smell. A professional water test can tell you exactly what is in your water and whether a filter is needed.

If you live in an older home with galvanized pipes the inside of the pipes may be corroding.

Is Chlorine in Your Water Dangerous

The smell itself is not a health risk but it can be unpleasant.

Chlorine can react with organic matter in water to form disinfection byproducts like trihalomethanes. The EPA regulates these byproducts because high levels over many years may increase cancer risk. Charlotte Water tests for these compounds regularly and publishes the results in its annual water quality report. If you are concerned about byproducts a reverse osmosis system can remove them more effectively than a basic carbon filter.

For most people the bigger issue is the taste and smell rather than safety. If you are pregnant nursing or have a compromised immune system you might want to use a filter as a precaution.

How to Remove Chlorine Smell from Your Tap Water

The easiest way to reduce chlorine smell is to let water sit in an open container for a few hours. Chlorine is a gas and will naturally dissipate into the air. This works well for drinking water but is not practical for cooking or bathing. Boiling water for one minute also removes chlorine but again it is not a long-term solution.

For a more permanent fix consider installing a point-of-use carbon filter on your kitchen faucet. These filters use activated carbon to trap chlorine and other chemicals. They are inexpensive and easy to install but only treat water at one tap. If you want chlorine free water throughout your home you will need a whole-house carbon filter installed where the water enters your home.

Reverse osmosis systems are more comprehensive. They use a semi-permeable membrane to remove chlorine along with lead arsenic and other contaminants. These systems are installed under the sink and include a separate faucet for drinking water. They are more expensive than carbon filters but provide the highest quality water.

If you have a water softener it will not remove chlorine. In fact some softeners can make the smell worse by releasing sodium into the water. If you have both a softener and a chlorine problem you may need a separate carbon filter before or after the softener.

For those with sensitive skin a shower filter can make a big difference. These attach to the shower arm and remove chlorine before it touches your skin. They are especially helpful for people with eczema or dry skin. Some models also reduce scale buildup which can extend the life of your showerhead.
