Depending on the noise, it may be related, or something along the lines of the accessory drive belt has partially failed, and ripped the A/C compressor clutch wire loose.

Grinding on that end of the engine could be bad. Have you looked at it yet? Short of the center mount totally failing, and the engine hitting the frame, it could be the water pump going.
Or the A/C clutch has shorted to permanently on, and the compressor is making the noise, or it is the compressor bearing in the clutch.
Compressor not running, but the bearing is shot that the pulley spins on. Removing the belt will confirm/eliminate that. But you will have no PS. It could also be the PS pump too.
