When cloudy or milky tap water is isolated exclusively to a single faucet while all other fixtures in the house run crystal clear, the cause is typically a defective or clogged faucet aerator introducing excess air into the water stream. Over time, hard water mineral scale builds up inside the aerator mesh screen, creating a turbulent flow that whips air into tiny bubbles, making the water look milky. Additionally, a partially closed individual supply valve under that specific sink can create localized pressure drops and air turbulence. Verification: Unscrew and clean the faucet aerator tip to see if normal clear water flow returns.
