The 403 CMT Multilevel Well and Groundwater Monitoring System allows detailed discrete zone groundwater data to be obtained. Monitor up to 7 zones in one 1.7" well, or 3 in the narrow 1.1" (28 mm) Multilevel Well System.

The 403 CMT Multilevel monitoring well system is inexpensive, easy to install and most importantly reliable. It provides the user with a clear understanding of three dimensional groundwater flow and the distribution of contaminants in the subsurface. This allows remediation strategies to be targeted more precisely, and efforts being focused in the most effective manner. With use of the CMT Multi-level Well System, the monitoring of contaminant plumes is affordable. The system provides detailed vertical and horizontal data. The monitoring zones can be set as needed, with the single tube design permitting reliable seals between zones.

There are two multilevel monitoring well systems available. The 3 Channel Multilevel System, which was developed for smaller diameter installations, has 28mm (1.1”) polyethylene tubing. The 7 Channel Multi-level System has 43mm (1.7”) tubing, segmented into seven channels, allowing groundwater monitoring at up to 7 depth discrete zones.
