Each System <br /> is customized to suit monitoring needs,site conditions and <br /> budget constraints: - <br /> ► removable or permanent system <br /> ► bedrock or overburden application <br /> q <br /> groundwater or vadose zone monitoring <br /> Packers and ports can be accurately placed to monitor <br /> each zone of interest. <br /> Number of Monitoring Zones/Hole <br /> The maximum number of monitoring zones for a System Monitoring Options <br /> is determined by the number of tubes and/or cables that <br /> will fit inside the casing string. This number is dependent Dedicated sampling pumps and/or pressure transducers: <br /> on the monitoring options chosen. Systems can be Each monitoring port may be fitted with a dedicated <br /> designed to monitor from 2 to as many as 24 zones. sampling pump and/or pressure transducer.

This option allows monitoring with <br /> portable sampling and level measurement devices. This <br /> provides a very economical and flexible multilevel <br /> monitoring device. <br /> I` Mix of open tubes and dedicated equipment: A third <br /> option is to choose a mix of open tubes and dedicated <br /> equipment in different zones. This method combines the <br /> advantages of less expensive portable equipment for <br /> " shallower zones (i.e. 100 ft., 30 m) and the more time <br /> efficient dedicated equipment for deeper zones. <br /> >— - Water level monitoring only: The System can comprise <br /> pressure transducers only, for pressure monitoring in up <br /> to 24 discrete zones. <br /> �± t <br /> Borehole Size <br /> Waterloo or removeable packers are designed for use in <br /> 3"- 4" boreholes (75 - 100 mm).
