Below the SurfaceAuthor: Gunnar Haid & James Hammond
Casual chats between an Austrian and Australian on environmental topics that usually don't get talked about openly. Hosts Gunnar Haid and James Hammond set out to provide a light-hearted and thought-provoking look into Contaminated Land, Resource Recovery, Ecology and general environmental issues in Australia, in particular NSW. They use their experience and industry connections to talk about subjects that, at least in their opinion, don't get talked about enough or not in the right context. Join them for a chuckle and some unique perspectives. And don't forget to keep track of your listening experience.

#44 The Duplicate Pushback
Episode 44
Thursday, 4 June, 2026
In Episode #30 The Duplicate, Gunnar famously declared that duplicate soil samples in heterogeneous fill are useless. Risk assessor Belle Casement of Terravale Consulting heard the episode… and decided Gunnar needed correcting. 😲In this nerd-out episode, they discuss QA/QC, dodgy duplicates, lab uncertainty, conservative risk assessments, and whether the typical QC sections in contaminated land reports are actually science or just expensive pseudo scientific fluff we do to please regulators. Gunnar briefly ponders writing his own version of the ASC NEPM and re-introduces the term Quality Theatre in hope of getting it officially introduced into the Miriam Webster next year. They also get into lead, vapours, CRM samples, rinsates, trip blanks and upper confidence limits, with a completely unnecessary but somehow relevant detour into Henry VIII and Scientology. Nobody backs down, several sacred cows get kicked over, while Hammond tries hard to keep the two fighters apart and sometimes even dares to enter the ring himself. BTS Episode #30: The Duplicate - the OG duplicate episodeBTS Episode #11: he Sampling Evolution - Ross McFarlandListen to Below the Surface and collect CPD points.
