Why does my water sometimes look cloudy?

Occasionally the District receives customer inquiries regarding the appearance of “cloudy” or “milky” tap water. This condition is usually due to the presence of dissolved oxygen in the water supply. As the water passes through household water faucet restrictors and/or aerators, the dissolved oxygen collects to form small but visible bubbles. This appearance will typically clear within 30 seconds, as the bubbles rise and dissipate into the atmosphere. The cloudy or milky condition is not indicative of a water quality or public health concern.
