Why Does My Water Smell Like Bleach? Understanding the Chlorine in Your Tap
A distinct chlorine smell in your tap water is a common issue, and while it might be alarming, it usually indicates your water treatment system is working as intended. Chlorine is added to municipal water supplies as a disinfectant, killing harmful bacteria and viruses that could make you sick. However, an overly strong chlorine smell suggests a potential problem that needs attention. Let's explore the reasons why your water might smell strongly of bleach and what you can do about it.
What Causes that Strong Bleach Smell in My Water?
The most likely culprit is high chlorine levels. Water treatment plants carefully monitor and adjust chlorine levels, but fluctuations can happen. Several factors contribute to this:
- Increased chlorine dosage: The water treatment plant may have temporarily increased chlorine levels due to a detected contaminant or a seasonal change in water quality. This is often a temporary measure.
- Old or damaged pipes: If your home's plumbing system is older, the pipes might be corroding, releasing minerals into the water. These minerals can react with chlorine, leading to a more potent smell. This is also where a metallic taste might accompany the chlorine smell.
- Main line breaks or repairs: When there's a main water line break or repair, the increased chlorine levels are added as a precaution to disinfect the system before water service resumes. This is another temporary situation.
- Changes in water source: Water suppliers sometimes switch sources, and the new source might have different chlorine levels or other chemical treatments.
- Lack of proper water treatment at the source: In rare cases, insufficient treatment at the water plant could lead to higher than normal chlorine levels reaching your home.
Is it harmful to drink water that smells like bleach?
Generally, drinking water that smells slightly of chlorine isn't harmful. The chlorine levels are carefully regulated to ensure they are within safe limits set by the Environmental Protection Agency (EPA). However, a very strong or persistent bleach smell suggests a potential problem, and you might consider taking action. High levels of chlorine can irritate the skin and eyes, and some people find the strong smell unpleasant.
What can I do if my water smells strongly of bleach?
-
Contact your water utility: This is the most crucial step. Report the strong chlorine smell to your local water supplier. They can investigate the problem and inform you if there's a known issue, scheduled maintenance, or a change in the water treatment process.
-
Run your cold water for several minutes: This can help flush out any chlorine that has accumulated in your pipes. Let the water run from a cold tap for 5-10 minutes before using it for drinking or cooking.
-
Use a water filter: A good quality water filter, such as a carbon filter pitcher or a whole-house filter, can help remove chlorine and improve the taste and smell of your water. Consider installing a carbon filter pitcher if the smell is particularly bothersome.
-
Check your home's plumbing: If the problem persists after contacting your water supplier and flushing your pipes, consider having a plumber inspect your home's plumbing system for any potential issues, like corroded pipes.
How long will the bleach smell last?
The duration depends on the underlying cause. If it's due to a temporary increase in chlorine dosage by the water treatment plant, the smell should subside within a day or two. If it's related to your plumbing or a persistent issue at the treatment plant, it might take longer to resolve. Regular communication with your water supplier is key to getting this addressed promptly.
Can a strong chlorine smell in water indicate other water quality problems?
While a strong chlorine smell doesn't necessarily indicate other issues, it can sometimes suggest a potential problem with the water treatment process itself. If the issue persists, contacting your water supplier and requesting a water quality report might be worthwhile. They will test for other contaminants, ensuring your water is safe for consumption.
By following these steps and actively communicating with your water utility, you can address the strong chlorine smell in your water and ensure your family's safety and access to clean, drinkable water.
