*That's a  good question. **

**It's my understanding that the reason for copper plating a ground rod 
is to prevent the deterioration of the rods steel core. Why bother with 
protective coatings if a slowly deteriorating rod is just as effective 
as a new rod?

In my case, I have no way of knowing if the pitting found on the first 
foot of the rod isn't much worse down further so wouldn't it be best to 
either dig up one of the rods or simply replace them?
