A ground rod that is not connected to the electrical utility entry 
ground in in direct violation of National Electrical Code requirements.  
For the safety of yourself and others in your household, please add the 
missing wire.  If a fault condition happens in your house wiring that 
causes current to be carried on the 'green wire ground' conductor, the 
potential between your extra ground and anything connected to the 'green 
wire ground' can become quite high and anyone in contact with both can 
become a conductor.
