EPA will periodically update this compendium. If you would like to submit a resource for possible inclusion in this compendium, please contact Hal White (white.hal@epa.gov).
The resources below provide information about soil gas sample collection and sample analysis methods, focusing on sites where PVI may be a concern.
- Hers, Ian, Loretta Li, and S. Hannam. Evaluation of Soil Gas Sampling and Analysis Techniques At a Former Petrochemical Plant Site. Environmental Technology 25:847-860.
Presents an evaluation designed to provide information on reliability and selection of appropriate methods for soil gas sampling and analysis. The evaluation was based on a literature review of data and methods,and experiments completed as part of the research study. - Jewell, Kenneth P. and J.T. Wilson. 2011. A New Screening Method for Methane in Soil Gas Using Existing Groundwater Monitoring Wells (PDF). (13 pp, 1.0MB)
Ground Water Monitoring & Remediation 31(3): 82-94.
This study develops and evaluates a protocol to sample soil gas from groundwater monitoring wells that have some portion of their screen in the vadose zone. Using conventional groundwater monitoring wells as an alternative to installation of soil gas probes proved to be cost-effective and provided reliable results. - McAlary, Todd, Paul Nicholson, Lee Yik, David Bertrand, and Gordon Thrupp. 2010. High Purge Volume Sampling - A New Paradigm for Subslab Soil Gas Monitoring. Ground Water Monitoring and Remediation 30:73-85.
Presents a new method of monitoring that is based on a concept of integrating samples over a large volume of soil gas extracted from beneath the floor slab of a building to provide a spatially averaged subslab concentration. - McHugh, Thomas, Robin Davis, George DeVaull, Harley Hopkins, John Menatti, and Tom Peargin. 2010. Evaluation of Vapor Attenuation at Petroleum Hydrocarbon Sites: Considerations for Site Screening and Investigation. Soil and Sediment Contamination 19:725-745.
A framework for the evaluation of vapor intrusion at petroleum hydrocarbon sites that involves simple screening for preferential pathways at sites with sufficient vertical separation between the building and the source, but a more intensive investigation at sites with petroleum sources in closer proximity to the building.
