If you can be sure no wire, gas line or fiber optics are in the area, you
can drive a 6' piece of reinforcing bar into the earth, and use a grounding
block to connect to it for good earth ground. My understanding is that you
want the length of the wire connecting to the rebar as short as possible.

Some pipes are OK for a ground. But thay must be metal and only cold
water
pipes. Hot water pipes are connected to the water heater which brakes the
connection to ground.
