Hi All,
If I remember correctly from the archives, this was discussed some time ago.
It seems that copper ground rods last longer in alkaline soil and galvanized
rods last longer in acid soil.
As already pointed out, whichever type you use, do not connect copper parts
directly to galvanized parts. Use an intermediate metal foil or clamp such
as bronze or stainless steel plus antioxidant paste to help reduce
corrosion.
