||ETV Art's Manufacturing and Supply - AMS Dual Tube Liner Sampler
The Dual Tube Liner Sampler is a soil sampling tool
capable of collecting unconsolidated subsurface material to depths
that depend on the capability of the advancement platform. The
Dual Tube Liner Sampler is advanced into the subsurface with a
direct-push platform. The Dual Tube Liner Sampler was demonstrated
in May and June 1997 at two sites: the Small Business Administration
(SBA) site in Albert City, Iowa, and the Chemical Sales Company
(CSC) site in Denver, Colorado. These sites were chosen because
each has a wide range of volatile organic compound (VOC) concentrations
and because each has a distinct soil type. The Dual Tube Liner
Sampler was compared to a reference method (hollow-stem auger
drilling and split-spoon sampling) in terms of the following parameters:
- sample recovery,
- VOC concentrations in recovered samples,
- sample integrity,
- reliability and throughput, and
The demonstration data indicate the following performance
and cost characteristics:
- Average sample recoveries for the Dual Tube
Liner Sampler were higher in clay soil and lower in sandy
- There was a statistical difference between
the VOC concentrations for one of the twelve Dual Tube Liner
Sampler and reference sample method pairs at the SBA site
and for three of the thirteen pairs at the CSC site.
- The integrity of the lined chamber of the Large-Bore
Soil Sampler was not preserved when the sampler was advanced
through highly contaminated soils.
- The Dual Tube Liner Sampler reliability to
collect a sample in the first attempt was higher than that
of the reference sampling method in both clay and sandy soils.
- The average retrieval time for the Dual Tube
Liner Sampler was quicker then the reference method in clay
soil but slower in sandy soil.
- The Dual Tube Liner Sampler costs for both
clay soil and sandy soil sites were lower than the reference
- The cost depends on the amount of samples
required, the sample retrieval time, soil type, sample depth,
and the disposal costs associated with drill cuttings.
