Waterloo Multilevel Groundwater Monitoring System*
The Waterloo System is used to obtain groundwater samples, hydraulic head measurements and permeability measurements from many discretely isolated zones in a single borehole.
The Waterloo System originated with Dr. John Cherry at the Groundwater Institute of the University of Waterloo in 1984. Ongoing development and refinement of the System by Solinst has taken place on a continuous basis since then.

Detailed 3-D Data
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.
The modular system can be customized for unique project requirements. This allows monitoring zones to be placed at desired depths using options suitable for either bedrock, overburden or combination applications.
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.
