Diving in on my water pump job. Would like to hear everyone's comments on this discovery:

I noticed that the front of the engine is covered in what I can only describe as rusty water stains. I hope its just a sign that the water pump is past-due, but I was wondering if it is maybe a sign of EGR cooler failure??
Any comments there would be appreciated.
Then again, it might just be mouse piss:
