TestAmerica Speaks on Data Quality Assurance for Vapor Intrusion Investigations at Upcoming Texas Conferences


William Elcoate, TestAmerica Air Product Manager, will present new developments for ensuring data quality in Vapor Intrusion (VI) investigations. The presentation will be given at the 2009 TCEQ Environmental Trade Fair and Conference on May 13, 2009, and Industry Council on the Environment (ICE) on May 21, 2009, in Austin, TX.

For the past 15 to 20 years, the risk potential for significant exposure to Vapor Intrusion had been suspected, but only until recently has a comprehensive approach to Vapor Intrusion investigations been developed to evaluate and address these risks. Many states have published guidances on Vapor Intrusion with the number increasing from 8 states in 2004 to approximately 28 today. All of the guidance does not adequately address the subject of chemical analysis and data quality. Understanding the data quality challenges associated with evaluating exposure from Vapor Intrusion is critical as human health exposure risk is being determined.

The presentation will evaluate various state guidances on Vapor Intrusion, assessing approaches and impact to data collection and analysis. Critical data impacts introduced from sample media, media certification, sampling protocols, and non-VI sources will also be addressed.

Mr. Elcoate has over 20 years of experience in the environmental testing industry and is currently a technical and regulatory expert for TestAmerica’s Air Testing Program. He has been actively involved in Vapor Intrusion seminars across the nation.
