Environmental Technology Verification Report: Soil Sampler, Clements Associates, Inc., JMC Environmentalist's Subsoil Probe

摘要

The EPA's National Exposure Research Laboratory, which demonstrates field characterization and monitoring technologies, selected Tetra Tech EM Inc. as the verification organization to assist in field testing. This document summarizes the results of a demonstration of the ESP (R). In 1997 EPA conducted a field test of the ESP (R) sampler. The performance of this system was compared to a reference subsurface soil sampling 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. Data quality indicators for precision, accuracy, representativeness, completeness and comparability were also assessed against project-specific QA objectives to ensure usefulness of the data. A complete description of the demonstration, including a data summary and discussion of results is available in this report.
