If you had some surface freeze protection, you wouldn't even need a water-glycol mix.
Anyways, I wonder if you have any ground water in the area?
Otherwise some of that heat you are pumping into the ground might built up after a while.
at 5' 6'' there is wet clay and i think somewhere around 6'-7' there is ground water
the guy i spoke to with the heat exchanger said that for my application wet ground is the best because the heat tries to drive the moisture away from the loop feild
my concerns really are with adapting my existing a/c unit
thanks for the replies
