If your tap water has a slightly “milky” appearance, you’re probably experiencing an interesting but harmless phenomenon known as “entrained air.” The milky color in the water caused by tiny air bubbles is harmless and is related to the operation of City wells.
The air is dissolved under pressure in the groundwater, much like carbon dioxide in a bottle of soda.
How to Detect
If your tap water is milky colored and you want to confirm you are experiencing entrained air, rinse out a clear glass twice and then fill it with cold tap water. After a few moments, the water should begin to clear from the bottom of the glass to the top as the bubbles rise to the surface. If the water does not clear, please contact us.
