|ETV Soil sampling Technology - Geoprobe Systems, Inc. Large Bore Soil Sampler
The Large-Bore Soil Sampler is a sampling tool capable of collecting unconsolidated subsurface material at depths that depend on the capability of the advancement platform. The Large-Bore Soil Sampler can be advanced into the subsurface with direct-push platforms, drill rigs, or manual methods. The Large-Bore Soil 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 Large-Bore Soil Sampler was compared to a reference method (hollow-stem auger drilling and split-spoon sampling) in terms of the following parameters:
The demonstration data indicate the following performance and cost characteristics:
