Another thing that we do is to bond all of the ground rods in an outside
ring which is buried in a trench filled with conductive concrete.  A
layer of the concrete, than the ground ring, and then another layer of
that concrete.  Expensive? You betcha, but cheap insurance for sites
costing well over a million dollars just for the infrastructure.
