Tug on the serpentine belt, (engine not running, of course), then see if it tightens up again when you release it. If it does not, suspect a weak or rusted spring-loaded tensioner.

Next, while it's running and squealing, dribble a little water onto the smooth backside of the belt. If the noise changes, check for a misaligned pulley or a worn belt.
