December Technical Seminar

ACLCA NSW continues it's monthly technical webinars with another free event for members on Wednesday 2nd December.  This event was originally scheduled for the end of November but has been re-scheduled due to an event clash.

Petroleum NAPL: Where is it and what’s it up to?  Matt Rousseau, GHD (Canada)

With continued movement towards more sustainable science and risk-based petroleum site management strategies, more and more LNAPL sites will incorporate a stage where at least some of the LNAPL will be passively managed in place. In order to justify this approach, there will be more onus on the development of LNAPL conceptual site models that are comprehensive, technically sound and, therefore, reliable. To get there, we will often have to answer complicated questions about where the LNAPL is, how’s its moving (or not), whether some fraction of it can be practically recovered (or not), and what natural biodegradation processes are up to. This presentation will provide an overview of options for characterising LNAPL extent/distribution and evaluating different aspects of LNAPL mobility. Methods for the evaluation of Natural Source Zone Depletion (NSZD) will also be briefly touched upon.  

Matt Rousseau is a Senior Environmental Engineer and petroleum NAPL Technical Lead with GHD based in Windsor, Ontario, Canada. His work focuses on the preparation of LNAPL Conceptual Site Models (LCSMs), the design of LNAPL site investigation programs, the evaluation of LNAPL mobility/recoverability/stability and natural source zone depletion (NSZD), as well as the development of LNAPL remediation and management strategies with a focus on sustainable risk-based solutions. Matt regularly provides training related to LNAPL behaviour, site characterization and remediation and has been involved in the development of related technical guidance documents in the U.S., Canada, and Australia. Most recently, Matt served as primary author of CRC CARE Technical Report 46 and host of the associated CRC CARE NSZD online masterclass. Matt has B.A.Sc. (1997) and M.A.Sc. (2000) degrees in Environmental Engineering from the University of Windsor in Windsor, Ontario, Canada.

Webinar details

The technical webinar will be hosted on MS Teams.  If your company does not use MS Teams, you can access the event online through your browser, or you can download the free MS Teams app. 

The webinar link will be emailed to members in the week prior to the event.

CPD Points

As with all ACLCA NSW technical seminars/webinars, you can accrue CPD points for attendance at our webinars.  However if you are joining the webinar via the app or browser or login as a guest, your name will not appear on the attendance list so you will need to type your name and company into the chat option before the event finishes in order for us to note this for CPD purposes.
