John Hunt is a renowned expert in contaminated land remediation and Senior Technical Adviser at Ventia. John has qualifications in geology and is Certified Site Contamination Specialist with more than 30 years’ experience in contaminated site assessment and remediation.

He started in the industry in 1992 with Groundwater Technology Australia as a contamination consultant. After 5 years with ADI Limited remediating former Defence munitions manufacturing sites, he joined Thiess Services (the precursor of Ventia’s remediation business) in 2000.

John has worked on many of Australia’s iconic remediation projects including the 2000 Olympics site, the Mortlake gasworks, the Rhodes Peninsula dioxin sites and Orica’s Botany Car Park remediation. Most recently he has become involved in PFAS remediation, a problem he had originally planned to leave to the next generation of practitioners to solve. He is a past president of ALGA and a long term member of the Sustainable Remediation Forum of Australia and New Zealand (SuRF ANZ), a specialist interest group of ALGA.

In this episode, John delves into the importance of problem definition in contaminated land management. He explains how diverse disciplines in geology, science, and engineering come together to tackle environmental challenges and emphasizes that miscommunication between these fields can lead to incorrect remediation approaches.

John discusses the evolution of sustainability in remediation, explaining how sustainable solutions are highly context-specific and depend on the environmental, social, and economic conditions of a site. He highlights the role of guidelines like ISO 18504 in providing a framework for sustainable remediation and encourages councils to integrate sustainability considerations early in project planning.

You will also gain insights from John's experiences on iconic Australian projects like the Sydney Olympics site and Rhodes Peninsula, where consultation with communities shaped effective and practical remediation strategies. He wraps up with advice for councils on staying up to date with emerging challenges, such as PFAS contamination and climate change impacts, and stresses the importance of forward-looking cost analysis in remediation planning.

Defining the Problem: John Hunt on Sustainable Remediation

Howard Waldron is the co-founder of Lotsearch, a company that has pioneered the development of environmental information and insights, with a particular focus on potential contamination.

Since the company was founded in 2014, they have been a provider of environmental and planning reports in Australia, helping support environmental consultants when undertaking preliminary site investigations.

More recently, Lotsearch have been engaged to help produce contaminated land registers for a consortium of regional councils across NSW, and by state and federal government agencies to undertake research in identifying potential contamination sources as well as supporting their assessments.

In this episode, Shonelle and Howard discuss the impact contaminated land registers have had on the way local councils manage potential contamination risks. Howard shares how these registers provide councils with vital data to comply with Section 10.7 planning certificates, improving transparency in property transactions and helping prevent environmental and human health impacts.

Howard highlights the importance of streamlining data collection, improving the accuracy of site investigations, and reducing the risk of contamination being missed.

He also shares insights into Lotsearch’s evolution over the past decade and explores how AI and machine learning are enhancing the accuracy of contamination data -- and what the future holds for environmental data in local government decision-making.

The Knowledge of Earth-Centered Cultures, the Key to Tackling Climate Change

In this episode, Shonelle chats with two special guests, Dr Danielle Toase and Dr Lange Jorstad.

Danielle Toase is an Environmental Manager, with a BSc in environmental science and PhD in environmental geochemistry. She has over 10 years experience across the fields of environmental research, regulation, remediation contracting, consulting and corporate environmental management.

Danielle has worked at multiple complex PFAS contamination since 2016, particularly at aviation sites or sites where multiple sources of PFAS exist. Her interests surround PFAS fingerprinting, source delineation, remediation technologies and the circular economy. Danielle is also an active member of ALGA, having recently been appointed to the Board of Directors and is an honorary research associate at Macquarie University.

Lange Jorstad is a Principal Hydrogeologist at Geosyntec Consultants, with a BSc in geological sciences from the University of California, Santa Barbara, and a PhD in contaminant hydrogeology from UNSW. He has over 20 years’ experience as a consulting hydrogeologist, specialising in contaminant fate and transport and environmental geochemistry.

Lange is a NSW EPA accredited Site Auditor and Certified Environmental Practitioner – Site Contamination Specialist, is an active member of the ALGA groundwater fate and transport special interest group, and provides university lectures on groundwater, contamination and sustainable remediation. He has provided consulting and auditing services for PFAS-contaminated properties for government and industry clients since 2015, including local development sites, fuel terminals, landfills, and airports.

You’ll hear how they got started in their respective fields, including Danielle’s PhD studies in Antarctica focused on chemical fixation of heavy metals in legacy landfills using orthophosphate and silica reagents.

Lange shares advice for local councils investigating landfills as a contamination source, and the evolution of groundwater remediation from pump and treat to in situ technologies, and Danielle discusses the purpose of PFAS fingerprinting and why it’s important especially in complex hydrogeology and sites with multiple potential sources of PFAS.

Becoming aware of a large project in the approvals process in their area can lead to much uncertainty and distress. A local council may become aware of a proposed development through the planning portal or from the developer themselves.

The vast majority of current renewable energy projects, for example, will be determined at a state level because they fall into the category of state significant development or Critical State Significant Infrastructure. That's why it's so important that council understands their role in the approval process and makes their voice heard through well researched submissions and negotiations during the development of the voluntary planning agreement.

Landowners can become aware of pending development plans through a variety of different avenues, including a letter that's been posted, a social media post, or a knock on the door.

Often, people will experience physical and mental wellness challenges because of resulting worry. They begin to wonder what will happen to their piece of paradise, whether they will receive compensation, and how they will retain a voice in the daunting power dynamic of dealing with developers.

Warwick encourages people in this situation to rally community, build a support network, and utilize professional advice from an environmental practitioner who is familiar with the Environmental Planning and Assessment Act and the assessment and determination process.

In this episode you’ll hear Shonelle and Warwick share stories about their mutual desire to see communication between developers and affected communities be more balanced. Too often, meetings seem to involve developers telling communities how the process will go, and Warwick believes a change in this dynamic will only happen when developers are truly convinced that it’s in their best interests to take the voices of the community into account, even in the early planning stages.
