I've removed 8' x 5/8" rods from firm earth and found the copper generally
intact. A water hose might be easier, but it can't match the intimate contact
that a driven rod attains. I've been able to use a rod driver (electric) a few
times and it makes the task much easier than pounding with a mallet.
I've read several books on grounding (enough to make me dangerous) and they
claim that bare wire or strap connecting the rods should be buried 12" to 18"
deep to avoid the "inductive effects" of the wire. I'm not completely in
agreement but do believe that the buried wire's reactance would experience
significant damping due to the distributed contact with ground, and, yes, the
deeper the better. Note that I said BARE WIRE.
