Answer: Cloudy water, also known as white water, is caused by air bubbles in the water. It is completely harmless. It usually happens when it is very cold outside because the solubility of air in water increases as water pressure increases and/or water temperature decreases. Cold water holds more air than warm water. In the winter, water travels from the reservoir which is very cold and warms up during its travel to your tap. The air that is present is no longer soluble, and comes out of solution. In addition, once water from our reservoir enters the transmission and distribution pipes, the water is pressurized.
If the amount of dissolved air is low, your water may appear to sparkle or have small bubbles. If there is a greater amount of dissolved air in your water, millions of very tiny bubbles will appear when the pressure is released, giving the water a cloudy or white, milky appearance. It may take several minutes for the air to escape. As it does, the water will clear from the bottom of the glass, upward.
