Is Milky Water Safe to Drink?

Published in Water Safety 3 mins read

Yes, generally, milky water is safe to drink.

Milky water often results from air mixing with the water due to various issues. These include:

  • Pipe problems
  • Changes in water pressure
  • Pipe disruptions
  • Nearby drilling activities stirring up sediment

According to our reference, even though milky water might look concerning initially, "it's entirely harmless and suitable for drinking or other uses." This means that the cloudiness is typically caused by air bubbles or sediment and does not indicate a water quality issue that would make the water unsafe to consume.


Common Causes of Milky Water

Here's a breakdown of reasons why your water might appear milky:

  1. Air Entrapment: This is the most common cause. Air can get trapped in water pipes, especially after maintenance or pressure changes. When you fill a glass, the air bubbles make the water look cloudy. The air will typically clear from the bottom of the glass upward in a few minutes.

  2. Sediment: Construction or drilling can stir up sediment in the pipes. This sediment, often harmless, can cause the water to appear cloudy. However, if the cloudiness does not settle after a few minutes, then consider further testing.

  3. Pressure Fluctuations: Changes in water pressure can also lead to air being mixed into the water supply.


What to Do If Your Water is Milky

If you notice that your water is milky:

  • Fill a glass and observe: Let the glass sit for a few minutes. If the water clears from the bottom up, the cloudiness is most likely due to air.
  • Run the cold water: If the milky appearance does not clear, run the cold water for a few minutes. This might clear sediment.
  • Contact your water provider: If the problem persists, contact your local water provider for advice and support.


Summary

Characteristic Explanation Is It Safe?
Cloudy Appearance Often due to air bubbles, sediment or pressure changes. Yes
Clears Up Quickly Indicates air bubbles; settles from bottom up. Yes
Persistent Cloudiness Could be sediment; contact water provider if not clearing with cold water running. Possibly, Check further


Therefore, based on the information provided, milky water resulting from air or sediment is typically safe to drink. Always observe the water and contact your water provider if you notice persistent problems.
