Hi, Ben and TTs;

Aluminum may fare better than copper in acidic ground but alkaline 
ground will corrode aluminum.  Jim Lux raises an interesting suggestion 
regarding sacrificial electrodes that might be generally useful where 
the ground is strongly acidic or alkaline.  I hope to hear more about 
that, and may turn to the books for some factual information.  Regarding 
connections, one must use appropriate connectors and conductive 
anti-corrosion compound, just as when making any clamped connection, be 
it for copper, aluminum, iron, or any other metal exposed to the outdoor 
environment or weld or braze the connections.
