I never checked with local inspection when I drove my ground rods into the
ground. All I know is what I took out and what was copper clad ground rods
were not copper clad after being in the ground for quite a while. They might
still be good ground rods, but were not in the same condition as when I
purchased them. That tells me they deteriorated from their original condition
and that is not good in my humble estimation. Maybe they are still good, but
seems that if they are not in the same condition as when first purchased that
they may be suspect as ground rods, but that doesn't say they may still deliver
the original intent as ground rods, etc.

The NEC does not preclude galvanized ground electrodes. Article 250.52 (A)(5)
indicates what is permitted by the NEC....it includes galvanized pipe and rod
electrodes. Note: Some local codes will prohibit galvanized electrodes due to
soil chemistry which will attack the zinc coating. There are UL Listed ground
rods available from some suppliers.

The copper coated rods eventually will deteriorate, I've found too. After
pulling them out I've found them speckled where the copper has eroded away and
the base material shown. I like the solid copper tubing as ground rods better,
but they are not that easy to embed. Use water to get them in the ground.

Frank,
You might know this since you have some tall towers up in the air.
Did the contradictions between NEC (copper ground rods) and EIA/TIA-222F
(12.2.2-galvanized steel ground rods) ever get resolved? At work we follow NEC
on comm buildings and are forced to follow 222 on tower structures.
The only place we’ve actually used some new galvanized steel ground rods was on
guy wire grounds on our 500 ft towers and only in the southeast part of
Nebraska with the known soil problems for galvanic corrosion. That was after
an inspection we found 1.5 to 2 inch holes on 4 inch anchors and the copper
rods almost totally gone.

NEC quotes relevant to this discussion:
Not less than two driven ground rods placed at a minimum of 6 feet
apart when a non-metallic water piping system exists or is to be installed.
A separate grounding conductor to each ground rod shall be utilized
The grounding electrode conductor shall be solid or stranded, sized in
accordance with the requirements of the NEC but shall in no case be less
than No. 6 AWG copper or No. 4 AWG aluminum or copper-clad aluminum.
All ground rods will be required to be minimum 1/2" x 8' copper weld or
5/8” x 8’ copper plated only.
No galvanized rods or piping will be accepted as a grounding electrode.
