Detailed 3-D Data<\/h2>\n
When a number of Waterloo Systems are used at a site, they allow detailed three-dimensional groundwater information to be obtained at a reasonable cost. Fewer drilled holes are an advantage and monitoring times are reduced. <\/p>\n
The modular system can be customised for unique project requirements. This allows monitoring zones to be placed at desired depths using options suitable for either bedrock, overburden or combination applications. <\/p>\n
Discrete zone monitoring is the only means of obtaining accurate data for site interpretation and assessments. Transects of Multilevels provide the detailed data necessary to calculate mass flux and conservatively assess risk to receptors. <\/p>\n

Solinst Multilevel Groundwater Monitoring Systems<\/h2>\n
In addition to the <\/span>401 Waterloo System<\/strong>, Solinst manufactures two other multilevel systems, each suited to different environments and applications.<\/p>\nThe <\/span>615ML Multilevel Drive-Point Piezometer<\/strong> <\/span>has stainless steel monitoring ports connected using 3\/4\u201d NPT steel drive pipe and couplings. Dual barb stems allow the connection tubing to create up to 3 or 6 monitoring zones, depending on tubing size. Drive-Point Multilevel Systems can be installed simply using direct push methods, including a manual slide hammer. These systems are easy to transport with portable sampling and level monitoring options (see Model 615ML Data Sheet). <\/p>\nThe <\/span>403 CMT\u00ae System<\/strong><\/a> <\/span>consists of continuously extruded polyethylene tubing with seven or three separate channels running its length. Monitoring zones are mechanically created and sealed off, one in each separate channel at different vertical intervals. CMT offers in-field design flexibility, is low cost and easy to install. The 7-Channel System is 1.7\u201d (43 mm) and the 3-Channel is 1.1\u201d (28 mm). They are ideal for shallow applications in narrow diameter boreholes (see Model 403 Data Sheet). <\/p>\n*Manufactured under exclusive licence from the University of Waterloo.
