We measured our ground system during installation certain points.  The point that was in the retention pond meaured the highest earth resistance that three points not in or by the pond.  Hmmmm

Alan, what Polyphasor was reporting was government reports.  If you want I will be glad to supply the sources of the reports so you can review them.  I don't sell anything, I am only interested in enlightning our collective interest as a group of broadcast engineers.  I recognized that many of us may have expertise in areas that helpful to others, but rely on a industry with sells snake oil items that based on testimonial statements without scientific basis.  It may be hard for you to recognize the limitations on devices that you may have recommended to your clients, but seriously take a look the facts.

Bruce
