Vapor Intrusion occurs when there is a migration of vapor-forming chemicals from any subsurface source into an overlying building. Over the last several years, Vapor Intrusion exposure pathways has become a key factor guiding the regulatory closure process, thus it is important to fully understand and be fully engaged in the vapor intrusion data collection process. The Indiana Department of Environmental Management (IDEM) and many other state agencies offer guidance that include a series of steps to follow along with your data collection that compliment and assist in the data interpretation process. Without the information gathered during those complimentary steps, your analytical results are, at best, incomplete and have the potential to generate data that does not truly represent the concentration of contaminants coming into the indoor air through the subsurface soil. During this webinar we will give you an overview of a few key issues to consider when collecting vapor intrusion data and interpreting those results.
