  ETV Art's Manufacturing and Supply - AMS Dual Tube Liner Sampler
August 1998

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:

  1. sample recovery,
  2. VOC concentrations in recovered samples,
  3. sample integrity,
  4. reliability and throughput, and
  5. cost.

The demonstration data indicate the following performance and cost characteristics:

  1. Average sample recoveries for the Dual Tube Liner Sampler were higher in clay soil and lower in sandy soil.
  2. 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.
  3. The integrity of the lined chamber of the Large-Bore Soil Sampler was not preserved when the sampler was advanced through highly contaminated soils.
  4. 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.
  5. The average retrieval time for the Dual Tube Liner Sampler was quicker then the reference method in clay soil but slower in sandy soil.
  6. The Dual Tube Liner Sampler costs for both clay soil and sandy soil sites were lower than the reference sampling method.
  7. 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.
