TestAmerica Evaluates Current Trends in Vapor Intrusion at A&WMA Chapter and Section Forums


William Elcoate, TestAmerica’s Air Product Manager, will discuss current developments for ensuring data quality in Vapor Intrusion (VI) investigations. The presentation will be given at the Las Vegas Chapter Air & Waste Management Association’s (A&WMA) in Las Vegas, NV on November 12, 2008. A similar presentation, chosen from an abstract selection process, will be given at the Louisiana Section A&WMA Multi-Media Forum in Baton Rouge, LA on November 19, 2008.

The EPA published OSWER Draft Guidance for Evaluating the Vapor Intrusion to Indoor Air Pathway from Groundwater and Soils (Subsurface Vapor Intrusion Guidance) in November 2002. In recent years, it has become evident that the evaluation of the Vapor Intrusion pathway is significantly more complex than indicated by the original EPA Guidance. The Interstate Technology Regulatory Council (ITRC) published a guide in 2007, proposing more of a comprehensive approach to VI investigations. Many states are currently updating or have published new guidance drafts. A review of recent state documents will be presented, in addition to evaluating future regulatory trends that are starting to develop. The presentation will also discuss the best practices and practical considerations for pre-project planning, sampling & analysis, and the challenges of collecting representative data, where the presence of many variables can affect the reported data.
