Sometimes it’s not air. If the cloudiness doesn’t clear up in a few minutes, it might be sediment. This is mostly dirt, sand, or rust from old pipes.
Think of your city’s pipes like a giant metal straw. They get a little rusty over time. A construction project nearby can shake things loose. That puts grit in your glass.
Why Is My Tap Water Cloudy or Milky?
This looks more like a murky fog than a fizzy cloud. It usually settles to the bottom of the glass. It’s not dangerous, but it tastes like a muddy rock you found in a puddle.
Fun fact: If you live in a house built before 1986, your pipes might be made of lead. That’s a real problem. But cloudy water isn’t a sign of lead. If you’re worried, get a simple test kit from the hardware store. It’s cheap and fun.
