  Note: The Solinst Tag Line, (Model 103), is recommended for accurate sand and bentonite placement.
Note: On the underside of the wellhead is a groove to fit 2” dia. PVC riser pipe.

CMT Placement
21) Lower the assembled CMT System into the borehole slowly.
If buoyancy is a problem, wait, as the channels below water level will slowly fill and allow the system to be lowered further. To speed this process along, pour or pump clean water into the vent holes.
When the required depth is reached, suspend the system with the System Support Clamp to prevent it from moving during well construction (Figure 22).
22) Complete the installation by carefully pouring or using a tremie to place sand and bentonite at appropriate levels to seal the borehole annulus
