The objective of this project was to demonstrate and validate a suite of tools that can improve our ability to more accurately, cost-effectively, and confidently assess vapor intrusion VI impacts and, if necessary, select appropriate remedies in neighborhoods and industrial buildings overlying dilute chlorinated solvent plumes. The project focused on advancing the VI Diagnosis Toolkit, which includes external VI source screening for at-risk building identification building-specific controlled pressurization method CPM testing to quickly measure worst-case VI indoor air impacts in at-risk buildings indoor vapor source identification through use of portable analytical tools passive samplers for longer-term week to month duration, time-weighted indoor air concentration measurement and use of the data from all tools to select appropriate mitigation strategies, if needed. Protocols and guidance for use of these tools were developed, demonstrated and validated in residential and industrial buildings as part of this work.
