Have you ever turned on your faucet and noticed that the water coming out is cloudy or milky? If so, you’re not alone. Cloudy tap water is a common issue that many homeowners experience, and it can be both frustrating and concerning.

While it’s natural to question the quality and safety of cloudy water, it’s important to understand that there are several factors that can contribute to its appearance. In this article, we’ll explore three of the most common causes of cloudy tap water and provide actionable steps to address the issue.

Before we delve into the causes, it’s essential to note that while cloudy water may look unappealing, it is not always a sign of contamination or health hazards. In many cases, the cloudiness is due to harmless factors that can be easily resolved.

With that in mind, let’s explore the common causes of cloudy tap water and what you can do to address them.

Cause 1: Air Bubbles

One of the primary causes of cloudy tap water is the presence of air bubbles. When water is pressurized in the pipes, tiny air bubbles can get trapped and create a milky appearance when the water is turned on. This phenomenon is often referred to as “aeration.”

Aeration can occur for various reasons, such as changes in water pressure due to maintenance work or an event that disrupts the flow, such as a pipe burst or repair. It can also happen when the water is being transported from the reservoir to your home.

If you suspect that air bubbles are causing your tap water to appear cloudy, there are a few simple steps you can take. First, let the water run for a few minutes to see if the cloudiness clears up. This will allow any trapped air bubbles to escape from the water and restore its clarity.

If the cloudiness persists, try filling a glass with water and letting it sit undisturbed for a few minutes. If the cloudiness gradually disappears from the bottom up, this is a clear indicator that air bubbles are the cause. Simply let the water sit for a bit longer until it becomes clear again.

It’s important to note that aeration-induced cloudiness is temporary and does not pose any health risks. However, if the cloudiness persists for an extended period of time or if you notice any unusual odors or tastes, it’s best to consult a professional plumber or your local water supplier to ensure there are no underlying issues.

Cause 2: Dissolved Minerals

Another common cause of cloudy tap water is the presence of dissolved minerals. Water naturally contains various minerals, such as calcium, magnesium, and iron, which can become dissolved and suspended in the water supply. When these minerals reach a certain concentration, they can give the water a cloudy or hazy appearance.

The level of dissolved minerals in tap water can vary depending on the source and treatment process. Hard water, which is characterized by a high mineral content, is more likely to cause cloudy water. This is because the minerals can precipitate out of the water and form tiny particles that scatter light, resulting in a cloudy appearance.

If you suspect that dissolved minerals are making your tap water cloudy, there are a couple of solutions you can try. One option is to use a water filtration system or a water softener. These devices can help remove or reduce the minerals, resulting in clearer water.

Another option is to use a water clarifying agent. These products are specifically designed to bind with the minerals and other impurities in the water, helping them settle at the bottom of a container. This can make it easier to pour off the clear water and leave behind the cloudy sediment.

It’s worth noting that while dissolved minerals can make your tap water appear cloudy, they are generally harmless to consume. In fact, some minerals like calcium and magnesium can even have health benefits. However, if you have concerns about the mineral content or if the cloudiness persists despite trying the above solutions, it’s best to consult a water treatment professional for further guidance.

Cause 3: Microorganisms

The presence of microorganisms is another potential cause of cloudy tap water. While it may sound alarming, it’s important to remember that not all microorganisms are harmful or pose a health risk. In fact, our water supply naturally contains a certain level of microorganisms that are generally harmless to humans.

However, certain types of microorganisms, such as bacteria or algae, can proliferate and cause water to become cloudy. These microorganisms can enter the water supply through various sources, such as untreated or poorly treated water sources, or from environmental factors like changes in temperature or exposure to sunlight.

If you suspect that microorganisms are causing your tap water to appear cloudy, there are a couple of actions you can take. First, you can try running the water for a few minutes to flush out any stagnant water that may be contributing to the cloudiness. This can help improve the water’s clarity.

Another option is to use a disinfecting agent, such as chlorine or hydrogen peroxide, to kill any harmful microorganisms. These agents can be added to the water or used in combination with a water filtration system to ensure the water is safe to consume.

If you continue to experience persistent cloudiness or notice any unusual odors or tastes in your tap water, it’s advisable to contact your local water supplier or a water treatment professional. They can assess the situation and provide guidance on how to address any potential issues with microorganisms or other contaminants.

Remember, while microorganisms can be a cause of cloudy water, not all cloudiness is attributed to them. It’s always best to consult a professional to accurately identify the cause and determine the appropriate course of action.

What to Do

If you encounter cloudy tap water, here are some simple steps you can take to address the issue:

  1. Run the water: In many cases, simply running the tap for a few minutes can help clear up the cloudiness. This allows any trapped air bubbles or sediment to flush out of the pipes and restore the water’s clarity.
  2. Check for system maintenance: If you notice that the cloudiness coincides with maintenance work in your area, such as flushing of water mains or repairs, it’s likely that the issue will resolve itself once the work is completed. In such cases, it is advisable to wait a few hours and then check the water again.
  3. Use a water filter: Consider installing a water filtration system to remove impurities, such as dissolved minerals or microorganisms, from your tap water. There are various types of filters available, ranging from countertop systems to under-sink models. Be sure to choose a filter that is designed to address the specific concerns you have about your water quality.
  4. Consult a professional: If the cloudiness persists or if you have any concerns about the safety or quality of your tap water, it’s best to consult a professional. This can be a plumber, a water treatment specialist, or your local water supplier. They can assess the situation, perform water tests if necessary, and provide expert advice on how to address any underlying issues.

Remember that each situation may be unique, and the appropriate steps to take will depend on the specific cause of the cloudiness in your tap water. It’s important to consider factors such as water source, geographical location, and treatment processes when determining the most suitable course of action.

By taking these proactive measures, you can ensure that your tap water remains clear, clean, and safe for use.


Cloudy tap water can be a cause for concern, but it’s important to remember that in most cases, it is not a sign of contamination or health hazards. By understanding the common causes of cloudy water and knowing what steps to take, you can address the issue effectively.

Air bubbles, dissolved minerals, and microorganisms are among the leading causes of cloudy tap water. Fortunately, these issues can be resolved through simple actions such as running the water, using filtration systems, or consulting professionals if necessary.

It’s important to stay informed about the water quality in your area, especially if you notice persistent cloudiness or other unusual characteristics in your tap water. Regular maintenance and testing can help ensure that your water remains clear and safe to use.
