Solinst 403 CMT Multilevel System, a Resolute Advantage

The Solinst CMT Multilevel system was developed in 1999 and has been a success with some 5000 installations all over the world. RS Hydro have extensive experience in working with clients in the UK and Ireland who choose to use this system.

This multilevel system is reliable, easy to install and inexpensive. It provides site assessors with a better understanding of three-dimensional groundwater flow and the distribution of contaminants in the subsurface. Remediation strategies can then be targeted more precisely, focusing efforts in the most effective manner. The CMT Multilevel System makes the accurate monitoring of contaminant plumes much more affordable.

It provides detailed vertical as well as horizontal data. Monitoring zones are set where needed and the single tube design allows reliable seals between zones. Two systems are available. The 1.7" (43 mm) OD polyethylene tubing, segmented into seven channels, allows groundwater monitoring at up to 7 depth-discrete zones. The 3-Channel System uses the same material and construction, but it is only 1.1" (28 mm) in diameter. This narrow tube was developed for smaller diameter installations, especially direct push where the annulus for seal placement is narrow.

Research has shown that contaminant plumes are often thin and highly stratified. It has also been documented that traditional monitoring wells, with long screened intervals blend the groundwater over the entire length of the screen**. This can mask the true contaminant concentrations and distribution. Multilevel wells with short screened intervals overcome this problem. This high resolution data gives unprecedented definition of the subsurface contamination, resulting in more effective and less expensive remediation. Water quality data from short-screened wells yield high quality, defensible data.

In Summary the Advantages of Multilevel Systems are;

• Provide the most accurate 3-D assessment of a site


• Vital to understanding vertical contaminant distribution


• Allow documentation of changes in the concentration and delineation of contaminant plumes


• Low cost compared to multiple individual wells


• Minimize site disturbance

Full support in the UK & Ireland;

We pride ourselves on staying with the client all the way through the process, from sale, training and project completion. We have received training as part of our exclusive distributorship in the UK & Ireland with Solinst and can provide on-site training with any CMT project.

Easy to work with on site;

As we have mentioned the multilevel system is easy to construct after some basic training. Randy Blackburn, Product Manager, Solinst Canada demonstrates how to assemble a sampling point in this video.

Solinst have a wealth of information available, from technical releases, FAQs, case studies and academic papers covering just some of the many installs they have been involved in. Click here to view or download from our website.

If you have any questions about this system please feel free to contact me directly, I'd also be interested in speaking to existing clients who have the CMT system installed on a site.
