Environmental Technology Verification Report: Passive Soil Gas Sampler. W. L. Gore and Associates, Inc., GORE-SORBER (Trade Name) Screening Survey

摘要

This document summarizes the results of a demonstration of the WL Gore and Associates, GORE-SORBER (R) screening survey passive soil gas sampling system. The performance of this system was compared to the reference sampling method, active soil gas sampling (which provides a snapshot of the soil gas environment at the time the sample was collected). The comparison addressed three parameters VOC detection and quantitation; sample retrieval time, 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.
