Description of Solinst Model 403 CMT Multilevel Systems
The CMT Multilevel System has been dependable, affordable, and simple to install since 1999. It helps site assessors better comprehend the distribution of pollutants in the subsurface and the three-dimensional flow of groundwater. Then, remediation tactics can be more specifically focused, concentrating resources in the most efficient way possible.
The CMT Multilevel System significantly lowers the cost of precise pollutant plume monitoring. It offers comprehensive horizontal and vertical data. Where necessary, monitoring zones are established, and dependable sealing between zones are made possible by the single-tube architecture.
About Solinst Model 403 CMT Multilevel Systems
Continuously extruded polyethylene tubing with three or seven distinct channels running the length of the tubing makes up the Model 403 CMT Multilevel System. Each channel has a monitoring zone that is manually built, screened, and sealed off at various vertical intervals. In a single groundwater monitoring well, this enables the System to monitor up to seven depth-distinct zones. These systems can be designed in a variety of ways, and monitoring ports can be built on the drilling site.
The diameters of the narrow 3-channel System and the 7-channel System are 1.1″ (28 mm) and 1.7″ (43 mm), respectively. Unlike numerous clustered or nested wells at different depths, backfilling around these single tube systems is straightforward.
The 3 and 7-channel Systems can be backfilled with standard methods of bentonite seals and sand packs. The 3-Channel System has the option of using pre-formed bentonite and sand cartridges, which can be positioned on the CMT and installed using direct push methods.
CMT Systems can be used to accurately measure water levels and take water samples. Solinst offers narrow diameter, portable Water Level Meters and samplers that can be used in the CMT. A wellhead seal is available to allow vapour sampling.
The CMT System provides many benefits to site assessors.
- Inexpensive and easy to install and use
- No joints – smooth surface for easy sealing
- Up to 7 depth-discrete monitoring zones
- Locate ports and seals exactly where needed
- Installs quickly using direct push methods or in boreholes
- Lowers risk of cross contamination and new contaminant pathways
- Provides a 4D view of groundwater flow and distribution of contaminants in the subsurface
Solinst offers courses for CMT construction and installation. Contractors who complete the course are “Trained CMT Contractors” and can be listed on the Solinst website.
