Actually, this leads into a similar problem we run into in northern California.
Many areas here are cursed with Adobe soil which never dries out, not even
after eight years of drought. Code here permits/requires the ground rod be
placed under the concrete, usually in the garage, as close to the service
entrance as possible. In moist ground, subjected to the alkali leach from
the concrete, they literally dissolve in 2-3 years. I have put in two new
ones that have already vanished, away from the concrete... and I have been
here only ten years.

What this means, is that in a Modern home in  California, The Earth ground
is a myth. The phone company grounds their lines in sand filled holes......
