A rare, but harmless phenomenon is being reported by the City of Wellman regarding their tap water. In a statement released to the public, the city is currently experiencing cloudy or “white water” that is caused by bubbles in the water.

City officials state that this usually happens during cold outdoor temperatures or temperature changes. Cold water holds more air than warm water, as does pressurized water. Once the water leaves the tap, it warms and is no longer under pressure and the air leaves the water as bubbles, similar to a carbonated soft drink. The city suggests residents let the water sit in an open container until the bubbles naturally disappear. The issue has been reported to the Iowa Department of Natural Resources.
