The Massachusetts Department of Environmental Protection (MassDEP) finalized their Vapor Intrusion Guidance: Site Assessment, Mitigation, and Closure document on October 14, 2016.  As stated from the guidance, “This document provides guidance on investigating, assessing, understanding, and mitigating vapor intrusion at disposal sites regulated under Massachusetts General Law, chapter 21E and the Massachusetts Contingency Plan.”

The vapor intrusion guidance was in draft form since October 2014 and went through a lengthy public review process prior to it being finalized.  For the most part, there were no substantial changes from the public comment draft version of 2014 to the final guidance; however, there were numerous changes in terminology and clarifications on various items throughout each section.
