Monitoring Well Installation

The Geoprobe drill rig has the ability to use a variety of drilling techniques to install permanent monitoring wells.

Depending on geology, Ecoprobe can :

  • Solid stem Auger: sandy clay, weathered rock
  • Hollow Stem Auger: sand, running sands
  • RAB: clay, weathered rock
  • Down Hole Hammer: hard rock

Once the hole has been completed, up to 80mm casing can be installed. Standard construction, gravel pack, bentonite seal, grout or replace cuttings to surface and a gatic cover or steel riser completes the well. Finally a 12 volt pump is used to purge the well.
