Monitoring with SEAMIST{trademark} from soil venting to landfills -- Where it works best and not so well
- Eastman Cherrington Environmental, Santa Fe, NM (United States)
This is a review paper of the progress of the SEAMIST{trademark} technology from its conception to its wide range of current applications. The monitoring function seems to be its role of most advantage. The original purpose of SEAMIST{trademark} was to wick moisture from fractures in unsaturated rock. The pneumatically driven everting membrane allows the ideal emplacement off absorbent material against the hole wall. However, the greater use is to transport tubing into a borehole, seal the borehole, and isolate multiple sampling ports in the same hole. That high spatial resolution also allows the extraction of large volumes of pore fluid as often as desired. Hence, the history of pore fluid composition, pore pressure, permeability changes, arrival of tracers or nutrients, and many other parameters have been determined at the many sites described across the country. The limiting factors are assessed as a function of the site and application. The method has been extended to use under new landfills (e.g., mixed waste landfills), via prefabrication of the access passages. An evaluation for the Department of Energy by the Los Alamos National Laboratory shows the SEAMIST{trademark} method to be cost competitive in deeper installations or when multiple measurements are desired.
