7 and 3-Channel CMT with Wellhead

3-Channel Sand & Bentonite Cartridges

The Micro Double Valve Pump

The 403 CMT® Multilevel System* provides the simplicity and low cost of a bundle-type installation, with the benefits of backfilling or sealing around a single tube.

The CMT offers low cost multilevel monitoring up to 7 zones in a single tube, with no joints. The narrow 3-Channel System is ideal for installation using direct push rigs. For such installations, bentonite and sand cartridges are available to give reliable seals between zones. Fast installation ensures the hole is not left open to deteriorate or contaminate.

The CMT System uses continuous polyethylene multichannel tubing which is custom-built on site with screened intervals at desired sampling zones. Reliable seals and sand packs can be placed around the single tube using standard backfill methods, or using pre-formed cartridges in the 3-Channel System.

The CMT Multilevel allows detailed 3-D water levels and water samples at an affordable cost. Detailed transect monitoring of plumes using CMT Systems enable zones of high concentrations to be identified quickly, simply, and at less cost. This gives data that allows better decision-making.

Water levels can be accurately established and samples taken using small diameter portable equipment available from Solinst. If preferred, a sampling tube can be dedicated to a channel that is not needed for water level monitoring. Special wellhead seals are also available to allow vapor sampling in the system.
