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. <\/span><\/p>\n[\/et_pb_text][et_pb_image src=”https:\/\/www.solinst.com\/wp-content\/uploads\/2024\/10\/403-cmt-logo.webp” alt=”solinst model 403 cmt multilevel system logo” title_text=”Solinst Model 403 CMT Multilevel System Logo” align=”center” _builder_version=”4.27.2″ _module_preset=”default” width=”25%” custom_margin=”20px||||false|false” global_colors_info=”{}”][\/et_pb_image][et_pb_image src=”https:\/\/www.solinst.com\/wp-content\/uploads\/2024\/10\/can-multilevel-groundwater-monitoring-be-inexpensive-1.webp” alt=”can multilevel groundwater monitoring really be inexpensive and simple” title_text=”Can Multilevel Groundwater Monitoring Really Be Inexpensive and Simple?” align=”center” _builder_version=”4.27.2″ _module_preset=”default” custom_margin=”20px||||false|false” global_colors_info=”{}”][\/et_pb_image][et_pb_button button_url=”https:\/\/www.solinst.com\/products\/multilevel-systems-and-remediation\/403-cmt-multilevel-system\/get-quote.php” button_text=”Get Quote” admin_label=”403 get quote” _builder_version=”4.27.4″ _module_preset=”c9e00792-1360-4998-8cf9-5f6772c944ba” custom_margin=”20px||||false|false” custom_padding=”6px|47px|6px|47px|false|false” global_module=”3396″ global_colors_info=”{}”][\/et_pb_button][\/et_pb_column_inner][\/et_pb_row_inner][et_pb_row_inner _builder_version=”4.27.4″ _module_preset=”3676f7e6-7b83-4698-94ce-2cc9fa9ae43d” hover_enabled=”0″ global_colors_info=”{}” sticky_enabled=”0″][et_pb_column_inner saved_specialty_column_type=”3_4″ _builder_version=”4.27.2″ _module_preset=”default” global_colors_info=”{}”][et_pb_text admin_label=”research article” _builder_version=”4.27.4″ _module_preset=”default” hover_enabled=”0″ global_colors_info=”{}” sticky_enabled=”0″]<\/p>\n
CMT Multilevel System*
The Standard for Monitoring Wells<\/h2>\n
Since 1999, the CMT Multilevel System has proven to be 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. <\/p>\n
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. <\/p>\n
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. <\/p>\n
