Gunnar claims almost all duplicates we take serve close to no purpose. If you want to know why, have a listen and be entertained and informed at the same time.

The OGs are back together in this episode, and quite an unusual one it is. This times it is James who goes on a few rants, quite to Gunnar's amusement. Of course, Gunnar has a few things to say as well and he will definitively ruffle some feathers with this episode.

We start off with playing Wikileaks by talking about a letter the EPA sent to all auditors regarding the staged introduction of V3 of the PFAS National Environmental Management Plan (NEMP) and also a clarification regarding PFAS and the Duty to Report. (Plug to our previous Episode #25 The Duty to Report).

Then Gunnar and James hash out some ideas on duplicates, high RPDs, re-running of samples, basic statistics, experimental setups in science and why being 'conservative' might not be delivering the results you think it is.

Episodes we talk about:

#29 The OCSE Odyssey with Linda Apthorpe

#25 The Duty to Report with Elizabeth Wild.

#11 The Sampling Evolution with Ross McFarland

Attention Asbestos in Soils Specialists, there is a new kid in town. The Australian Standard 4964-2004 Method for the qualitative identification of asbestos in bulk
samples has been superseded with a new AS 5370.

What's different? What's better, what's worse? Why are we reporting below the detection and below the reporting limit? Is NATA on board with it? What do all those different sub-categories the laboratories report actually mean?

Gunnar is talking to Linda Apthorpe, a Certified Occupational Hygienist and Fellow of the Australian Institute of Occupational Hygienists (AIOH). Linda is Associate Principal Occupational Hygienist at Hibbs in Sydney, a Lecturer at the University of Wollongong, author of multiple scientific papers and speaker at a variety of professional development seminars. There are very few who are better suited to talk about this subject, especially since Linda was also on the panel of people who developed the new Standard.

James was unfortunately not there to keep Gunnar in check, and you guessed it, that resulted in not one, not two, but at least three (in)famous Gu-Rants in this episode. Some would say that alone makes this episode compulsory listening for anybody in the industry.

The Office of Chief Scientist and Engineer (OCSE) has issued recommendations concerning asbestos in waste and soil. Sarah Mansfield, Special Counsel (and environmental law superstar) at Norton Rose Fulbright, breaks down the key points and their legal implications.

Given the focus on the PoEO Act and its handling of asbestos, you'd expect at least one of our hosts to go off the rails with a classic, epic rant. But, against all odds, age, wisdom, and a dash of professionalism took the reins—so much so that this episode doesn’t even come close to earning the 'explicit' rating it sometimes gets on various platforms.

Gunnar's composure alone is a highlight (though he admits to biting his tongue to the point of unhealthiness!). Add to that the invaluable insights from James and Sarah, and you've got an episode well worth your time. We loved making it as always, and we hope you enjoy every moment.
