Time to call the well-driller, drill a narrow well about 50' deep and put in a 
slurry of bentonite and drive'em in, couple them every 10' and keep going... 

Now how much would that 50' hole cost?

I bought one of these things and a large Bosch demo hammer.
Works great in dirt.  When it hits rock it stops and rod bends.
Is there a drill that works and does not come apart?  (SDS-Max chuck)
On my hill in WV, about 4 feet down the sand and clay quit and I hit solid 
sandstone.  3/4 rod did not help the situation.  When the rod hits refusal it 
is over.
