Brisbane Branch Event - Commercial Realities - Ground Gas and Vapour Intrusion Assessments in the Land Development Context

The evening is planned to be an introductory and thought-provoking event where Q&A will provide opportunities for interaction and feedback from the audience. This will inform a more focused and technical event later in the year.

Five speakers will provide a brief presentation on vapour intrusion and landfill gas assessment designed to introduce participants to key concepts, followed by an interactive session.

The attendees will have the unique opportunity to explore and hands-on experience of two innovative devices used for HGG risk assessment and vapour sampling. Notably, one device has not yet been released to the general market.

This event is particularly relevant for anyone involved in environmental risk assessment offering a hands-on experience and valuable insights. Don't miss out on this informative session.



Your ticket includes one complimentary drink and a selection of appetizers. Please note that this is not a formal dinner event.

BYO! To minimise our use of plastic, we encourage delegates to bring their own reusable water bottles and coffee cups.
