Sourdough have some good advice, albeit a bit confusing when referring to using the meter on ohms setting. The bottom line is to take an ohm reading from the ground pin of the receptacle to a known good ground and the reading should be right at zero ohms. If it reads open our has a high resistance, the pedestal has an open ground just like the EMS reported to you

An inverter would be in incoming ac power.
