This application uses the everting FLUTe liner to seal the hole in order to isolate the
discrete sampling ports from one another. The method is described under
Vadose FLUTe system.
The Vadose FLUTe system is:
- Very quick to install
- Seals the hole exceptionally well
- Easy to sample
- Fully removable (unless installed permanently).
The liner system is often installed from a pressure canister with air
as the driving fluid. Many recent installations are via the interior
of a driven casing in unstable media, where the liner is left
sand filled (and hence not removable, by customer choice).
Details of the method are at
Vadose Gas Sampling method.

Vadose FLUTe systems
are used to measure contaminants such as TCE, Tritium, Methane and other gaseous components.
Another application is to measure the pore gas pressure history with depth to assess barometric pumping or vertical permeability. The liners are easily installed horizontally beneath landfills. The gas sampling function can be combined with other uses on the same liner such as water sampling, absorber collection of pore liquids, and towing of logging tools. Tracer injection or extraction is well within the capability of these multi level gas-sampling liners.
