Solinst Model 401 Waterloo Multilevel Groundwater Sampling System
- Low cost
- Steady release for constant microbial activity
- Deep applications to 800 ft (240 m)
- Easy installation and removal
Overview
The Model 401 Waterloo Systems can be used to achieve groundwater samples, hydraulic head measurements and permeability measurements from many discretely isolated zones in a single borehole.
A number of Waterloo Systems can be used onsite, which would allow detailed three-dimensional groundwater information to be obtained at low cost. Fewer drilled holes are an advantage as monitoring times are reduced.
This simple modular system is specially customised for the needs of each project. This allows monitoring zones to be placed at desired depths using options suitable for either bedrock, overburden or combination applications and with either permanent or removable systems.
The only means of obtaining accurate data for site interpretation and assessments is through discrete zone monitoring. Transects of multilevels provide the detailed data necessary to calculate mass flux and conservatively assess risk to receptors.

Specification
| PVC frame wrapped with tubing , Sized for 2", 4" and 6" (50, 100 and 150 mm) wells, stackable to allow the controlled continuous diffusion of gas into the plume. | |
| Materials | For particular applications specific materials may be chosen. These may include stainless steel casing and packer bodies, and stainless steel, nylon or PTFE/FEP tubing. |
| Borehole Size | Waterloo or removable packers are designed for use in 3"- 4" boreholes (75 - 100 mm). Systems can be installed in larger boreholes using: - Placement of sand and bentonite to isolate parts around a Waterloo casing string with no packers. - 3-4" screen and casing, installed within a larger hole, completed by installing a Waterloo System with packers. |
