Put the belt back on and start the engine. Then turn on the A/C. See if the sound changes when the compressor kicks in.
With the engine running - very carefully check the powersteering fluid for bubbles (you'll probably need a falshlight for this). If bubbles are present, then the pump may be leaking. Some resistance is normal - but bubbles are not.
With the belt off - check the water pump pully for side to side and up and down movement. There should be none. If there is change the pump.
