Vapor Intrusion Reference Guide: State by State

The science used to evaluate potential vapor intrusion (VI) into buildings is evolving constantly.  As this occurs, the federal government and individual states are updating their regulations, but not always in a consistent manner.  If you are a person responsible for environmental management in multiple states, you have several challenges.  One among them is trying to stay up to date on the “fluid nature” of VI regulation and standards.  As an aside, Dragun’s vapor intrusion video discusses the way that VI concerns are driving more and more projects.

With this “challenge” in mind, Dragun has created the quick-reference table below.  By simply clicking on a state, you can access information and links about how that state currently regulates VI.  In addition, where possible, we have included the standards for a few of the common chemicals of concern for VI exposure.

By simply clicking on a state, you can access information and links about how that state currently regulates VI.

It’s worth repeating the obvious – VI standards are changing constantly.  We cannot guarantee that the standards have not changed since the creation of this quick-reference table.  Each page provides the date that the information was last updated.

If you would like to be informed when we provide the updates, you can add your name to our mailing list on the right side of this webpage.
