I have just taken off the water pump pulley to see where the water leak was coming from only to discover a hole in the top front of the water pump housing.
It's a perfect hole with no thread. Water is leaking out of here.
Most, if not all, water pumps have a weep hole to allow lubrication from the bearing to escape the pump without going into the coolant. If coolant is leaking from that hold, the internal seals of the pump have failed and a new pump needed.
