Jewell, K., C. Paul, C. Ruybal, J. Skender, AND J. Wilson. Petroleum Vapor - Field Technical. Presented at 23rd National Tanks Conference and Expo, St. Louis, MO, March 18 - 21, 2012.
Presentation for the 23rd National Tanks Conference in St. Louis, MO, on March 18-21, 2012.
The screening approach being developed by EPA OUST to evaluate petroleum vapor intrusion (PVI) requires information that has not be routinely collected in the past at vapor intrusion sites. What is the best way to collect this data? What are the relevant data quality issues and data quality requirements? How should the data organized and used to inform a decision? Have you ever wondered how this stuff really works? Here is your chance to see it demonstrated. Instructors will demonstrate the operation of commercially available equipment that provides information on concentrations of oxygen, carbon dioxide, methane, and combustible gases in air. They will demonstrate the use of field meters to determine concentrations of oxygen, methane and carbon dioxide in the soil gas, as well as demonstrate the construction and application of traps packed with Granular Activated Carbon (GAC) to remove gasoline hydrocarbons which can seriously interfere with the measurement of methane in soil gas. In addition, methods will be demonstrated to collect gas samples by water displacement that collects samples into glass serum bottles. The approach is much less expensive than collecting samples into Summa Canisters and analyzing by GC mass spectrometry.
