CMT Multilevel Systems isolate and monitor up to seven discrete zones in one borehole; monitor 7 zones in the 1.7' (43 mm) System; 3 in the narrow 1.1' (28 mm) System. Both options are low cost. The single tube design makes them fast and easy to drill and install in one day. System flexibility allows port locations and monitoring strategy to be finalized right on site. CMT wells are ideal for shallow applications to 150 ft (50 m). Depth discrete groundwater and soil gas data provides more detailed site characterizations, enabling increased confidence in decision-making.
