Coolant leak

[Viper5]

After thinking about what is happening with the dripping of fluid, I have come to the conclusion that the hose is OK. The nut is OK. I strongly believe that the leak is actually above the point of drippage. I'm leaning towards a bad pump, but what other possible parts could it be if it's dripping from right above (which is right where the pump is located)? Basically, I want to know if any other possible part could be failing causing a leak at that spot. Or maybe due to a lesser expensive part such as an o-ring or gasket.

Also, if it is indeed the water pump, will I be able to tell if I take a look at it tomorrow by tearing the firewall down and looking at it from a top view?

Another question is, if I remove the water pump, can I determine if it is the causation of the leak and if so, how?

Thanks.
