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.
So, a cold, cloudy day with no snow indicates that there is either not enough water vapor available to the cloud, or that the rising motion creating the cloud is not enough to cause snow (or both). A heavy snowfall results from abundant water vapor combined with strong and persistent rising motion in the clouds. Snow can also form from very cold air flowing over a large ice-free lake, a situation called lake effect snow. In mountainous regions, air being forced to rise as it flows up and over the mountain can cause large snowfall accumulations.
