Flexible liner publications date back to 1989 when Carl Keller began to present papers on flexible liner techniques at NGWA Outdoor Action conferences. Those are primarily of only historical interest, but several are still useful. They are:

1. The utility of absorbers for collection of pore water in the vadose zone.
2. Landfill monitoring designs of high reliability.
3. Other applications of everting liners (e.g., robotics, decontamination of ducting).

More recent publications are Power Point presentations with colorful summaries of the several FLUTe methods. These are available on a CD which can handle high resolution photos of installations. Request the CD at This CD also contains some of the drawings of this site, but in a larger, more legible format.

Other publications available are on subjects related to the use of liners:

1. How deep must a blank liner be installed in a hole to provide an adequate seal?
2. How fast will a liner descend in a hole and how can that information be used to deduce the conductivity profile?
3. What is the procedure for installing liners horizontally beneath a landfill?
4. What are the best tubing materials for sampling ( a US Army Corps of Eng. report)?
5. What are the limiting factors in deducing formation conductivities from recharge rates of the sampling system?
6. How can the NAPL liner removal be used to deduce formation conductivities?
7. Relative quality of various borehole sealing methods.

Other subjects related to the use of liners can be discussed with the FLUTe staff, since they are not explicitly treated in this web site:

1. The use of flexible liners to reline piping.
2. Installations through hollow stem augers.
3. Installations from tunnels vertically upward.
4. Transport of instrument strings along lakebeds under water.
5. Fire fighting methods using liners.
6. Flotation devices using everting liners.
7. Predictive models used to assess liner loads such as drag in tortuous passages.
8. Soil sample recovery using liners.
9. Novel wicking designs for liners.
10. Comparison of FLUTe methods with any other method (pros and cons).
11. FLUTe patent numbers covering devices and methods on this site.
