Australasian Land and Groundwater Association 2018 EcoForum

Groundwater Ecoforum 2018 Menard Oceania

October 2018 – Remediation and more specifically how to mitigate the environmental impact of per- and polyfluoroalkyl substances (PFAS) was a hot topic of discussion at Australasian Land & Groundwater Association (ALGA)’s 2018 EcoForum, which was held in Sydney, earlier this month.

Menard Oceania and REMEA’s remediation experts Marika Sallot des Noyers and Jonathan Hale were onsite throughout ALGA’s 2018 EcoForum. The team had some great discussions with a wide range of organisations and industries, all wanting practical advice and solutions for dealing with PFAS contaminated sites.

PFAS comprises a group of some 3,000 man-made chemicals that have been used since the 1940’s across a wide range of applications. Due to their unique properties, PFAS has been touted as one of the greatest emerging contaminants, sparking a lot of industry interest in how to remediate them or mitigate their impact. Right now, regulators are putting guidelines in place to help the many industries concerned with how they manage them.

REMEA’s Remediation Engineer Marika Sallot des Noyers also spoke at the 2018 EcoForum about a range of in situ remediation techniques that can be used for sites contaminated with VCHs’ (Volatile Chlorinated Hydrocarbons).

Marika explained that one solution does not fit all remediation challenges.  Through the presentation of 3 case studies, she guided the audience through various elements of the decision-making process to ensure the in situ remediation technique selected is best suited to the specific site conditions.  She also explained the advantages and limitations of each in situ technique presented.
