I saw an interesting article about creating a good earth ground reference a couple days ago.

In some cal lab they dug a deap hole to the water table, filled it partially with rocks, and then put their ground rod in their. Then they filled up the hole and this whole thing was supposed to keep a better contact with the earth through all types of temperatures and humidities. I didn't read the whole article because it was incredibly boring....but that seemed extreme.

Here at my lab, we just stuck a giant copper wire deep into the ground (i think around 10ft or so).
