Talking PFAS Episode 44 Show Description/Notes/Links
INTRO:
Welcome back to Talking PFAS podcast. I am a journalist and your host Kayleen Bell. If you are new to the podcast, I encourage you to have a binge listen, as the content is, of course, still very relevant today as attention, regulation and litigation regarding PFAS chemicals continues to accelerate.
Today’s discussion is an Interview with two guests who were training people at the CRC Care Risk to Remediation Masterclass in Newcastle from the 1-5 May, 2023.
My guests are Paul Nathanail from Nottingham, England, Technical Director of LQM, which specialises in contaminated land management in England and around the world. I have previously interview Paul before, when he was a keynote speaker at CRC Care International Clean Up Conference in Adelaide, South Australia. You can hear that very important discussion in episode 37.
My second guest is Scott Warner, from California, who is a geologist, and has specialised as a hydrogeologist studying and assessing groundwater conditions, for 40 years. Scott is the Principal Hydrogeologist for the BBJ Group.
In early May I had the privilege of attending one of the training days at the CRC Care’s 4th Risk to Remediation Masterclass. This course was held from the 1-5 May, 2023, at Newcastle (NSW), Australia. I interviewed Paul and Scott at the end of a long week and a long day of very in depth training. It is important to clarify that this was not a course that was solely dedicated to PFAS remediation but remediation in general, which included PFAS.
CRC Care provided me with this information following the event:
“The CRC are Risk to Remediation Masterclass was a five-day course that provided participants with the cutting edge skills to manage and remediate contaminated sites in Australia and globally. This course was developed in response to the critical need to build capacity to address the growing global contamination crisis.
While technical lessons learned through the study of past projects an advantage of this course was the semi-structured discussions problem-solving and personal interactions that allowed participants to consider the many facets of modern contaminant site assessment and remedial design.
The course also discussed aspects of sustainable low impact remediation approaches, climate change considerations, policy and regulatory matters and economic considerations, all within the context of gaining and maintaining a social licence to operate.
There were 75 delegates present, and the Masterclass 2023 was attended by delegates from Australia and from overseas. The delegates were from a varied background and experience. They were from Department of Defence, regulators for EPA VIC and EPA Tasmania, Federal Government, consultants and practitioners, academia, scientists, researchers and early career professionals. And the overseas delegates were from Malaysia and South Africa. Now to my discussion with Paul Nathanail from the UK and Scott Warner from California.
Special thanks to CRC Care for allowing me to attend.

OUTRO: (With Important PFAS News from Australia)
I hope to bring you some information from the ALGA event that I attended at the end of April later in this season.
PFAS NEWS AUSTRALIA
I have some big. Australia PFAS news. You might have heard me mention a Super Class Action which is now being referred to as a Multi-Site PFAS Class Action.
The following information is largely taken from a Shine Lawyers media release, but not all is a direct quote.
The applicants in the multi-site PFAS Class Action represented by Shine Lawyers have reached an ‘in principle’ agreement with the Commonwealth to settle the multi-site PFAS Contamination class action against the Department of Defence.
These are residents from seven communities across Bullsbrook (WA), Richmond (NSW), Wagga Wagga (NSW), Wodonga/Bandiana (VIC), Edinburgh (SA), Darwin (NT), and Townsville (QLD). Shine Lawyers state that those seven communities were set to head to the Federal Court for the start of a trial which would examine the Commonwealth’s alleged responsibility for the spread of PFAS chemicals from military bases across the country into neighboring communities soil and groundwater.
Shine lawyers fought to compensate residents living near these military bases after their properties lost value due to contamination caused by these toxic chemicals and the parties have agreed in principle on an amount of $132.7 million and the break-up of that amount is yet to be determined but it could include up to 30,000 people. Shine Lawyers joint head of class actions Craig Allsop said while the news is positive the outcome is still subject to approval by the Federal Court.
Shine Lawyers will continue to pursue compensation for residents of Wreck Bay in the matter of Wreck Bay Aboriginal Community Council and Anor -v- the Commonwealth. And Justice Lee ordered a further remediation in the Wreck Bay proceeding and stood the hearing down until the 29th of May.
I hope to bring you more about the super class action in the future in the podcast. And I encourage any of the residents who were involved in this class action and would like to share their PFAS story to please reach out to me at [email protected]

Show Notes: Talking PFAS with Peter Murphy, MD EPOC Enviro (OPEC Systems) regarding PFAS remediation using their SAFF Foam Fractionation Technology – Published Wed 26/4/2023
Welcome back to Talking PFAS podcast. I am a journalist and your host Kayleen Bell. If you are joining us for the first time a very big welcome. I encourage you to listen to past episodes, with a range of really excellent guests from around the world.
Just before I introduce today’s guest, I encourage you to have a listen to Episode 42, which published yesterday. It is an update of the US EPA's proposed regulations regarding PFAS in drinking water. If the proposed MCLs are approved they will become mandatory levels. As discussed in last week’s episode the guidelines and regulatory limits for certain PFAS keep going down. The number of PFAS lawsuits keep increasing, and the number of PFAS contaminated sites keeps growing. This means there will be no shortage of PFAS remediation work for quite some time.
In fact, in a PFAS remediation special edition of the Environmental Business Journal published in 2019 they state, and I quote:
“The Environmental Business Journal has wrestled with the extent and scale of the PFAS Era in market terms. The EBJ has published a working model which reflects a consensus on the scale of the emerging PFAS market. The EBJ model includes major contributions from both waste and wastewater system upgrades and lifestyle costs as well as remediation. The model published in 2019 points to the possibility of expenditures in excess of $160 billion over the next 20-30 years and over 40,000 sites or facilities where significant PFAS contamination will likely be identified and treated or remediated at some level.”
Today’s discussion is another chat about a PFAS remediation method. Today’s guest is Peter Murphy Managing Director of an Australian based company, OPEC Systems. OPEC Systems trades as EPOC Enviro around the rest of the world which stands for Emerging Pollutants of Concern.
Today we will be discussing at length EPOC’s PFAS remediation technology for removing PFAS from water and landfill leachate using their SAFF systems. We also discuss the challenges that short chain PFAS compounds continue to present to remediators and how the SAFF has navigated these challenges so far.
SAFF system trials have already been conducted in Oakey QLD at a Department of Defence site, and at a landfill site in Telgay Sweden. These two systems have now moved out of their trial period into a fixed contract period. SAFF has also been trialed in UK, as well as an undisclosed location in the US on the East Coast of New York and will be involved in projects in Spain, Germany, Massachusett’s and Minnesota.
And just recently announced on the 13/4/2023 EPOC Enviro announced plans to open a major manufacturing facility in Statesville, North Carolina, with the first US built SAFF units scheduled to start PFAS remediation work in July 2023.
Pete Murphy from EPOC states in their recent media release: “Our award-winning SAFF technology has already visited eight different US states, and we are looking forward to leveraging this impact to all corners of the globe including back home in Australia to help communities remediate their PFAS impacted waters.”
However, despite the huge investments in remediation technology that are happening around the world, very little if any money has been invested to come up with solutions to clean up private land or farms that have been contaminated by PFAS. That is certainly the case in Australia and indeed also in many other parts of the world. I discussed this scenario very briefly with Pete today at the end of the episode.
Please note: I am an independent journalist and a podcaster no money was received for today’s interview. If in the future money is received from remediation companies (as sponsorship) to support the continuation of this podcast I will disclose this. Also any discussions with remediation companies is for information purposes, I am not endorsing any product or remediation method over another.

Show Notes
Talking PFAS Episode 42 – Published 25/4/2023
Welcome back to Talking PFAS Podcast. I am a journalist and your host Kayleen Bell.
Today’s episode is the launch of Season 6, and I want to give a big thank you to everybody who continually listens to Talking PFAS podcast, and for sending me your emails on how much you enjoy it. If you are new to the podcast, I encourage you to have a binge, as the content, of course, is still very relevant today as attention, regulation and litigation regarding PFAS chemicals continues to accelerate.
In the Talking PFAS episode today we will be taking a closer look at what US EPA is doing regarding their proposed PFAS drinking water regulation. And it is important to note that I will be giving an overview, from their overview, so for you to get the full context of what they are doing, I strongly encourage you to look at their website.
Also I really encourage you to look at their two webinars. One was on the 16/3/23 and one was on the 29/3/23. They are excellent. They will give you all the information that you need whether you are somebody affected by PFAS contamination, or responsible to keep it out of drinking water, or responsible to clean it up. And also, they go into great detail in parts of these webinars, but for the most part they are very easy to understand.
I just need to mention, in the intro, the proposed PFAS National Primary Drinking Water Regulation, that US EPA has proposed, is not an enforceable regulation yet, as some information online and some news articles have reported that it is. It is simply a proposal at this point.
Today I am going to share some key information from the US EPA webinars on these proposed changes to drinking water regulation and I will put a link in my show notes. And also the US EPA is running a virtual public hearing on May 4 and they are asking people to register and submit comments. They will also take oral comments and written comments for this public hearing on May 4. Throughout today’s discussion I am always talking about US EPA if I just say the word EPA, just for clarification.
I will also be sharing some of my interview with Boston Attorney John Gardella from CMBG3 Law. This is a repeat from Episode 33 but I will not be publishing the whole of Episode 33. But as we were discussing all of these changes it is relevant to today’s episode just to give people who are concerned about the legal ramification of these proposed changes. So, I will be replaying it for the benefit of those listeners that are interested in litigation.
So why is the US EPA proposing these drinking water regulations regarding PFAS. As they stated in the webinar, “they are taking this action because safe drinking water is fundamental to healthy people and thriving communities.” EPA stated, “we rely on water from the moment we wake up and make a cup of coffee to when we brush our teeth at night. Every person should have access to clean, safe drinking water. That is why EPA is acting now to protect people’s drinking water from PFAS contamination.”
As they stated in the webinar “The science is clear. Long-term exposure to certain PFAS is linked to significant health risks.” They continue to quote “people can be exposed to PFAS in a number of ways and when their drinking water is contaminated with PFAS it can be a significant portion of a person’s total PFAS exposure.” This is very important to note, “based on EPA’s evaluation of current best available science, PFOA and PFOS, are found to be likely human carcinogens.”
Commenters on the proposed rule have until May 30th this year, 2023, to provide comments to the agency on the proposed rule. Comments must be submitted to the public docket by May 30th for consideration.
So, EPA is proposing a National Primary Drinking Water Regulation (NPDWR) to establish legal enforceable levels called Maximum Contaminant Levels, (MCLs) for short.
Under the Safe Drinking Water Act, EPA has the authority to set enforceable National Primary Drinking Water Regulations for drinking water contaminants and require monitoring of public water supplies. To date EPA has regulated more than 90 drinking water contaminants but has not established National drinking water regulations for any PFAS.
Now the Agency is developing a proposed National Primary Drinking Water Regulation for PFOS and PFOA and additional certain other PFAS. The EPA is also considering regulatory actions to address groups of PFAS. The Agency expects to issue a final drinking water regulation by the end of 2023, after considering public comments on the proposal.
I am now going to play a portion of my interview with Boston Attorney John Gardella from Episode 33, and I will ADD in some more relevant US EPA information around this, including the impacts that the new mandatory drinking water limits, if passed, will have on public water system providers.
Now Boston Attorney, John Gardella, has been a regular guest on the Talking PFAS podcast. It is always a great, open and easy to understand conversation with him. He is well-versed on PFAS and writes frequently in the National Law Review and you can catch up on his multiple PFAS articles there.

Welcome back to Talking PFAS podcast, and if you are joining us for the first time, a very big welcome. I encourage you to listen to previous episodes. I am a journalist and your host Kayleen Bell. This is the last episode of Season 5. I will be taking a publishing break until the end of March, as I conduct some more interviews. Before I introduce today’s guest, I have some news. I am very pleased to announce that a collection of my PFAS interviews is now available as an oral history collection in the QLD State Library. I will put a link to that collection in the show notes.
Today’s guest is the second last guest from the 2022 International Clean Up Conference posted by CRC Care, held in Adelaide, South Australia. I have one more interview from Germany and that will go up in the break.
My guest today is Dr Scott Coffin, a Research Scientist, with the California State Water Resources Control Board. This is the Agency in California that governs the drinking water and all other water resources. What I think was significant about this discussion with Scott was that from his position working for the California State Water Resources Control Board he was willing to share openly about PFAS and California’s water issues. Here is a little of what he said:
“So California has a legal mandate to ensure all of the data that we collect on the environment is transparent and accessible to the public. It is a law since 2015, the Open Water Data Act and this means that any consumer in California, or anyone living in California, can find out what is in their drinking water, if they have PFAS monitored, even if it is unregulated which it often is they can find that information.” (Dr Scott Coffin)
Since commencing this podcast in 2018 I have not found that same level of openness or willingness in Australia from water providers to talk about PFAS. I believe it is time that the Australian water providers, those people tasked with providing safe drinking water to the public, actually become more transparent about what is in the public’s water. And in particular advise whether PFAS or other contaminants are present.
I hope you enjoyed today’s episode and a very big thank you for listening. If you enjoy the Talking PFAS podcast I encourage you to please share with colleagues, friends, associates and get the word out about this podcast. I love receiving the emails from listeners telling me how much you enjoy the podcast.

Welcome back to Talking PFAS podcast. I am a journalist and your host Kayleen Bell.
Please note I am having some technical challenges with some podcast players not updating to my latest episode, especially Apple Podcasts and Spotify, which I am in the process of fixing. I apologise for any inconvenience. But you can always find the latest episode on my podcast host Omny Studio, and Podlink, Castbox, Podcast Addict, Podlink and Google podcasts. If you enjoy this podcast please share to encourage more listeners to find this podcast.
This is the finale for Season 5 of Talking PFAS. I will be releasing two more episodes from international speakers from Clean-Up Conference 2022 in January, one speaker from California (up next) and one from Germany. This will complete the series of interviews I recorded at Clean-Up Conference (2022).
My guest today is Dr Mark Bowman, who is a Technical Director working for GHD based in Sydney, Australia. He has worked on PFAS since 2005 helping to assess, clean-up and manage risks associated with their use. Dr Bowman is widely published on PFAS management, and he also presented a session at the 2022 Clean-Up Conference on emerging contaminants, including PFAS.
PFAS is a key focus for the team at GHD and Dr Bowman said their team had a strong presence at the Clean-Up Conference with up to 18 people attending including five from their Americas teams who are some of the leading people in North America dealing with PFAS and emerging contaminants.
Dr Bowman said “GHD is championing PFAS response for clients in the Asia Pacific, Americas and Europe-Middle East. The company has industry leading PFAS response capabilities and is the most experienced and trusted team working to protect people and the environment from PFAS.”
He also states: “GHD is successfully delivering PFAS contaminated site assessment, soil-water-sediment remediation, human health and ecological risk assessments, statutory audits, monitoring and strategic program management. GHD also assists clients transition away from PFAS including advising on replacements and performing decontamination of plant and infrastructure.”
In today’s episode Dr Bowman says a key take-away is this message, “it is fine to use a chemical that has been approved for commercial use but we need to ensure that unlike some of the challenges with PFAS where they have been dispersively released and haven’t controlled how we have used those chemicals that has been a key take-away. We need to really not let those chemicals out into the environment in the first place. It often doesn’t matter what the chemical is. We don’t want it in our drinking water. We don’t want them in our food. We want to have safe, breathable air. We want to have safe drinking water and it is best to ensure that we are not releasing chemicals into areas that we are using for food and water.”

Welcome back to Talking PFAS Podcast, and if you are joining us for the first time a very special welcome. I am a journalist and your host Kayleen Bell. Today’s episode was also recorded in September in Adelaide, South Australia at the International Clean-Up Conference.
My guests today are Gavin Scherer and Rachael Casson from AECOM and first up I will be speaking with Gavin Scherer. Following my chat with Gavin I will be speaking with Rachael Casson, and you will hear her introduction before my discussion with Rachael.
Gavin has over 23 of consulting experience in environmental and contaminated land assessment and remediation. The past 15 years has been in the service of AECOM. During his time in AECOM Gavin has led teams in both Australia and New Zealand including Australia’s largest geosciences and remediation services team, the Australian Department of Defence client account as well as Australia and New Zealand’s PFAS response teams. Currently Gavin leads AECOM’s global PFAS commercialisation strategy, which includes focusing AECOM’s global team to develop, trial and bring to market a world-first onsite cost effective PFAS destruction solution known as De-Fluoro and Gavin is going to explain what De-Fluoro is in today’s episode.
Rachael serves as a Director of AECOM’s International PFAS Program focusing on innovation and technical excellence. She has over 22 years of consulting experience in contamination, assessment and management. In 2008, Rachael recognised the emerging concern over PFAS with aviation and Defence clients positioning the AECOM team at the leading edge of the PFAS science. She has worked on over 100+ PFAS related projects across the globe. Rachael is part of the De-Fluoro Technical Development Team an electrochemical process that destroys PFAS in solution. Her other research programs include plant PFAS uptake study and evaluation of the transformation of PFAS precursors into perfluoroalkyl acids (PFAAs) downgradient of known source zones.
AECOM’s De-Fluoro technology won the CRC Care Innovation Award at the 2022 International Clean-Up Conference in Adelaide. The CRC Innovation Award recognises researchers and environmental consultants who develop innovative ways to monitor, assess and remediate environmental contamination. The Award aims to inspire industry, businesses, communities, local government, schools and individuals to take action toward a more sustainable future. AECOM’s De-Fluoro technology is one of the first commercially available economical and environmentally sustainable on-site destruction treatment for high concentration PFAS waste. AECOM’s Global Initiative Leader, Gavin Scherer said the technology uses electrochemical oxidation to break the carbon-fluorine bonds in PFAS which causes the molecules to break down.
An estimated $2-$4 billion dollars worth of work is required to treat PFAS over the next decade.

Welcome back to Talking PFAS podcast and if you are joining us for the first time, a very special welcome. I am a journalist and your host Kayleen Bell.
To finish this season of Talking PFAS I will be publishing the remainder of the audio I recorded in September in Adelaide at the International Clean Up Conference, hosted by CRC Care.
Today’s guest is Dr Richard Stewart, he is the Managing Director of RemBind which is a local company based in Adelaide, Australia, but also has global reach. They sell PFAS remediation products globally. He is going to be talking today about the RemBind stabilisation product for PFAS and this is for use in soil. It is added to the soil and it binds up PFAS and prevents it from leaching into the groundwater. I managed to drag Richard off his stand at the Clean Up Conference in Adelaide for a very quick chat.

Welcome back to Talking PFAS podcast. I am a journalist and your host, Kayleen Bell.
Episode 37 - Published 25/11/2022.
Thanks for being patient listeners (as I have been unwell since the Conference). It is good to be back with new episodes.
For the next several weeks I will be bringing you episodes recorded at the International Clean Up 2022 Conference held in Adelaide mid-September, hosted by CRC Care. I have already published two interviews recorded at the conference, episode 35 and episode 36 and I encourage you to have a listen. There are six more to come from this conference, hopefully I can get them all up before Christmas, if not they will run into January, 2023.
Today’s guest is Paul Nathanail from Nottingham, England, Technical Director of LQM, which specialises in contaminated land management in England and around the world. Paul was a keynote speaker at the Clean-Up Conference and in today’s episode we will discuss details from his talk on PFAS. In brief, Paul believes we need to form an International Working Group to look at the entire universe of PFAS and then break this universe down into galaxies of individual PFAS substances that have more or less the same chemical properties and more or less the same toxicity properties. He will explain this in more detail in today’s discussion. I would like to point out that he refers to this universe of PFAS chemicals at around 9000, and at the last count that I heard, was 12,000, so the PFAS universe seems to be growing all the time.
Now to today’s chat with Paul Nathanail.
LQM (Land Quality Management) based in England but they work all around the world.
https://www.lqm.co.uk/
Their website states:
LQM is a specialist environmental consultancy based in Nottingham (UK) with an international track record of assessing and managing the risks posed to human health and the environment by contaminants in soil. Increasingly, this is being done within a context of sustainable development and specifically sustainable brownfield regeneration.”
About LQM from today’s discussion:
“We are specialists in contaminated land management (not just PFAS). LQM does high level consultancy. We write a lot of technical guidance. We developed the biggest set of soil screening levels that are used in the UK. I helped to write the International Standard on Sustainable Remediation. We run training courses. We write books and occasionally we go to conferences in far-flung placed like Adelaide.” Paul Nathanail, Technical Director LQM

The Heads of EPAs of Australia and New Zealand known as (HEPA) are about to release the draft version 3.0 of the National Environmental Plan (NEMP) for public consultation. This version contains important new guidance and standards which builds on version 2.0 published in 2020.
A brief overview on the draft NEMP was presented on Monday 12/9/2022 at Clean Up Conference 2022 in Adelaide by Dr Sara Broomhall who is the National co-ordinator for the PFAS NEMP & Director of Policy Advice and Integration Section from Department of Climate Change Energy, the Environment and Water.
As well as being National co-ordinator of the PFAS NEMP Sara has also covered things such as Stockholm Convention’s global monitoring work and the OECD chemicals work which sets a lot of the global standards about how we do risk assessment of chemicals.
The NEMP has had over 27,000 unique downloads and unique page views from over 50 countries. In NEMP 3.0 various areas requiring attention (leftover from NEMP 2.0) have been grouped under themes, and each theme is led by a jurisdiction in Australia and has a range of other jurisdictions participating and contributing to those themes.
In brief:
Theme 1 is PFAS Family – led by QLD – which will focus on international approaches to grouping.
Theme 2 is Environmental data and monitoring – led by VIC & QLD.
Theme 3 is Water – led by SA – and will focus on risk based criteria and guidance for beneficial reuse of biosolids.
Theme 4 is Soil – led by NSW – and focuses on PFAS behaviour in soil including leaching and guideline values.
Theme 5 is Resource Recovery & Waste – led by WA – which will focus on management of risks associated with PFAS in resource recovery products.
Theme 6 is Site Specific Guidance – led by the Commonwealth – and it has three projects operating under it. The first is a new section on approaches to remediation and management and Dr Sara Broomhall is the theme lead for that piece of work. The other two areas the Commonwealth will be responsible for is guidance on approaches to dealing with water from construction activities and then guidance on marine sediments.
Dr Sara Broomhall’s co-presenter on Monday (12/9/2022) was Dr Shaun Thomas who is a Principal Advisor for Wastewater in the SA EPA, and he is the lead on Theme 3. He is my special guest today.
Shaun is involved in the National Chemicals Working Group which works under HEPA and works on the NEMP. His main interest in PFAS is in biosolids and how we better manage the potential concentrations of PFAS in biosolids. Shaun said “no two territories and states have exactly the same approach for biosolids, and they took this into consideration. He said of the jurisdictions who had done some work already in the PFAS space QLD was the most prominent but his team also engaged quite heavily with NSW who have done a lot of work developing some guidance that hasn’t been published yet.

For the next several weeks I will be publishing episodes from PFAS discussions I had in person with a range of people at the International Clean Up 2022 Conference which was held in Adelaide, South Australia. This conference is hosted by CRC Care, and there were over 600 delegates (including about 100) online who attended from over 28 countries. There were over 230 oral sessions, and far too many PFAS sessions to count or for one person to attend them all.
Today’s guest is Professor Mark Patrick Taylor, and we will briefly discussed his research that he did with firefighters which used blood and plasma donations to reduce PFAS levels in their blood. This research was published around April 2022, and received a lot of media attention. We will also explore Mark’s opinion of what PFAS means in the environment and people’s concerns around this class of chemicals and he will also talk generally about impacts of other chemicals in our world and what he says we can all do about it.
The next discussion from Clean Up 2022 will be published on Monday 26/9/22 then weekly after that until the end of October.
