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.
