Sorry Allan, you're wrong.

The ESD Association recommends attachment to AC electrical ground. The standard method of attachment is to attach the ring terminal from the mat to the center screw of the grounded AC face plate cover.

On occasion attaching to a water pipe or ground rod is a safety hazard and may cause an electrical shock due to the difference in potential between that of the electrical ground and that of the earth ground.
