Assembling Standard CMT Systems

Assembling Standard CMT Multilevel Systems

Table 1 shows the design of a hypothetical CMT Multilevel System designated well "ML-1." Each channel in this well can be used for both collecting a groundwater sample (with either a peristaltic pump, inertial pump or micro double valve pump) and measuring the depth to water. Each channel therefore functions both as a sampling port and an observation port.

Note:

A 12.5 inch-pounds torqued port plug is designed to hold 20 psi (50 ft) of head differential.

 

Monitored Zone Channel Number Depth to Center of Port (from ground surface)
1 1 23 ft (7.0 m)
2 2 34 ft (10.4 m)
3 3 48 ft (14.6 m)
4 4 55 ft (16.8 m)
5 5 69 ft (21.0 m)
6 6 77 ft (23.5 m)
7 7 92 ft (28.0 m)
