Could be anything...That's why it is so frustrating. But all seems to indicate that it's in the water. We have tried various schemes to try to improve the contact between the water and the towers and the towers and earth ground and nothing seems to have worked. We contacted the testing company that did the original baseline ground data for us. They will come back out to take another look see. I'm hoping that with the additional test that we have run, they will be able to take a fresh look. I tried using my meter to see if I could read any voltage potential between the water and earth ground, but with the water in constant motion the readings on the digital are ambiguous at best.
