I went to the house where someone was being shocked by the water spigot and did some testing. Here's what I found, tell me what you think.

I tested the water spigot by putting one tester probe in the wet ground and touched the other probe to the spigot. It registered 13 volts AC. I also took a shoe off and touched the pipe and can confirm a nice flow of juice on the pipe. It's the same at the front and back spigot.

I checked and the pipes are bonded and from the ground in the panel a close pipe I get 0 volts and less then 1 ohm. So I know the grounding is OK from the panel to the disco where it is bonded to the neutral. From there I can see the ground wire go in the ground and I can't pull it out, but I can't see where it terminates either.

I plan to drive 2 new ground rods and see if it improves. What would you do? Any ideas.
