Vapor intrusion (VI) - the migration of contaminant vapors from subsurface soils and groundwater into buildings -  has become a leading concern for regulatory agencies across the country and in Indiana. The U.S. Environmental Protection Agency (EPA), Indiana Department of Environmental Management (IDEM) and other states have implemented vapor intrusion programs. In addition, the American Society for Testing and Materials (ASTM) released a VI standard (ASTM E 2600-08) in 2008 for evaluating this exposure pathway as part of the site assessment/property transaction process. The guidance documents put forth by these agencies continue to evolve. August Mack will provide an overview of VI and then discuss changes to Indiana's VI guidance, upcoming changes to the ASTM VI standard and other current information regarding this important topic.

Vapor Intrusion Screening for Real Estate Transactions
The question of how to address the risk posed by vapor intrusion (CI) has become a popular topic in real estate transactions, especially with the development of the ASTM VI Standard, "Standard Practice for Assessment of Vapor Intrusion into Strcutures on Property Involved in Real Estate Transactions" (ASTM E 2600-08). This webinar will consist of an overview of this ASTM standard and its four-tiered process. We will discuss why this standard was developed, what a VI assessment involves and when this standard should be used.
