I am not sure what your point is here:

Hold a live wire in one hand and a plastic pipe containing water in the other? So? What is the problem? I lost your point.

OK State that, but you did not address the well issue, and if the cold water pipe is grounded as being used as the grounding electrode, and only within five feet of entry into the building.

To answer the question to Jackofall, what you are allowed to do is install a green wire same size as the circuit back to one of several locations, now here is where it will get confusing to you.
My other point will be if you can run a ground wire from a 2 wire receptacle, why not run a new 3 wire cable and avoid trying to understand the following?
1. Attach to the grounding electrode system.
Do you have any idea what this is?
This IS NOT attaching anywhere on any metal cold water pipe in the home.
If you have metal water pipe serving the home, this is one electrode, as long as ten feet of pipe is in contact with the earth. You can attach to this pipe no farther than 5 feet away from point of enty into the home.
If you have a ground rod system, then attach to the ground rod.
2.Attach to an accessible point on the grounding electrode conductor.
This is the ground wire leaving your panel or meter and connects to the water line or ground rod.
3 & 4. Connect to the equipment ground bar OR the system neutral bar inside a panel or meter.
#3 & #4 requires you to enter the live panel, and forget about entering the meter.
So, now you see why ,if you can go through all the trouble of running a separate equipment ground wire, it would be better for many reasons to run new cable to this outlet.
Do not do as suggested by evolkmar, by connecting anywhere to any cold water pipe, only at the water pipe entraance and only if it is a grounding electrode, and never, never, never, just drive a separate ground rod to act as an equipment ground.
