Atlantic PIRI is pleased to release the final version of the Atlantic RBCA Guidance for Vapour Intrusion Assessments (December 2016). This document provides guidance on the assessment of vapour intrusion and is intended to supersede the User Guidance for Soil Vapour and Indoor Air Monitoring Assessments (Atlantic PIRI, 2006).
Thank you to all who provided commentary on the draft document during the Public Review Period. Revisions were made to the document because of this feedback, the most noticeable of which is the removal of chlorinated solvents.
Please refer to the Atlantic RBCA Guidance for Vapour Intrusion Assessments Implementation Procedure (December 2016) which outlines the implementation process for the new guidance.
