TestAmerica Addresses Data Quality Challenges Associated with Soil Gas Vapor Investigations at 2009 A&WMA Annual Conference


William Elcoate, TestAmerica Air Product Manager, will present new approaches for ensuring data quality for Vapor Intrusion (VI) investigations. The presentation will be given at the Air & Waste Management Association’s (A&WMA) 102nd Annual Conference and Exhibition on June 17, 2009 in Detroit, MI.

The risk potential for significant exposure to Vapor Intrusion had been suspected, but not until recently has a comprehensive approach to Vapor Intrusion investigations been developed to evaluate and address these risks. Many states are in the process of publishing their own guidance drafts on Vapor Intrusion with the number increasing from 8 states in 2004 to approximately 28 today. Many of these guidance documents do 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 for the determination of human health exposure risk.
