Cloudy Water

Cloudy Water

Drinking water delivered through the municipal system can sometimes look “milky” or “cloudy.” This cloudiness often occurs when air becomes trapped in the water. While this may impact the water’s appearance, it does not affect the water’s safety and will not harm household plumbing systems.

Source of air in the water

Air can be introduced in many ways and because water pipelines are pressurized, air remains trapped in the water until you open the faucet. This release of pressure is similar to the effect created when you open a bottle of soda. The thousands of tiny air bubbles that form give the water a slightly white appearance.

Cloudy water test

There’s an easy way to test whether cloudy water is due to trapped air. Fill a glass with tap water and set it on the counter. Observe the water for a minute or two. As the air dissipates, water should start to clear up.

Trapped air and water quality

It’s important to understand that this cloudy appearance does not reduce the water’s quality. Our Water Quality Technicians collect and analyze hundreds of drinking water samples a year from throughout our distribution system to ensure that your tap water meets or surpasses all drinking water requirements.
