AMS Dual Tube Liner Sampler (1,118KB)
Abstract
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
- cost.
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 soil.
- 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 sampling method.
- 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.
