From what I saw, grounding was an issue because the installers sometimes failed to connect the grounding straps, sometimes failed to actually tighten the connections, sometimes only put the rods into the ground a couple inches then cut them off to make it appear that they were driven in to proper depth.
Again, what I saw was work done before KBR got on site, work contracted directly by the Army.
I drove one in the nice New Mexican soil for my greenhouse. Took about an hour and I thought my arms were going to fall off.
if this is true these A-holes should be strung up! a ground rod has to be in the ground a minimum of 8 feet!
