You could put in a grounding rod nearby, find metal sewer line/drinking water lines, or pull a new wire to get a ground wire to the outlet. Check the circuit box the outlet is in, for a wire screwed to the box, that will be a ground also.
WRONG!!!! It\'s very dangerous! Electrical grounds must run WITH the wire back to the panel. Running a ground to a waterline created the chance of energizing the sinks, tubs, faucets etc. add a comment
