My tap water is cloudy-looking. Is that safe?
Sometimes during cold weather, tap water may appear cloudy or white, a condition caused by air bubbles in the water, according to Jeanette Klamm, programs manager for the city’s utility department. It’s harmless, she said, and happens because cold water holds more air than warm water. Klamm said bubbles will disappear if you set your water in an open container for a few minutes.
