Groundwater Fate & Transport

Understanding contaminant fate and transport in groundwater is fundamental to assessing risk posed by contamination as well as informing the development of risk mitigation measures and remedial actions.  Investing in this understanding is therefore not an expense but an investment to assist in resolving and closing out contamination issues.

There is a need for the scientific knowledge relating to contaminant behaviour and its application to the challenges of our industry to be discussed and communicated in a practical and relevant manner.

The main objectives of the group are to:

  • Identify, discuss and support the dissemination of practical knowledge of key topics in the field of groundwater fate and transport
  • Support the delivery of seminars and discussion panels on these key topics using relevant industry events around Australasia

Current Steering Committee Members (renewed each calendar year):

Frederic Cosme (Chair) – Golder Associates

Frederic is a hydrogeologist approaching 20 years of experience. He is passionate about contaminant hydrogeology, groundwater tracing using environmental and applied tracers and doing hand-drawings with colour pencils when developing conceptual models.

Camillo Coladonato – Dow Chemical

Camillo Coladonato is a geologist with more than twenty years of experience in contaminated land management. He has worked as an environmental consultant and for industry. He is currently responsible for the management of Dow Chemical’s historical environmental liabilities in Australia and New Zealand.

Greg Dasey – JBS&G

For over 20 years Greg has been involved in the assessment and remediation of sites with complex contamination and hydrogeological conditions.  Greg has special interest in sites where fate and transport of contaminants is influenced by diffusion and density dependent flow.

Joe Duran – Golder Associates

Joe has over thirty years’ experience as a hydrogeologist with expertise in contaminant source zone characterisation and the assessment of the fate and transport of associated dissolved phase plumes for a wide range of contaminants, including the characterisation of the impacts to associated surface water systems. 

Stephen Fenton – Chevron Australia

Stephen is a hydrogeologist with 10 years of experience. He has a keen interest in groundwater – seawater interactions and sustainable remediation.

James Fox – Land & Water Consulting

James has more than 17 years’ experience in both the public and private sector as a regulator and consultant. His specialist area is radionuclide geochemistry and fate and transport of radionuclides in the subsurface. James is a SA EPA Accredited Site Contamination Auditor and a Certified Practitioner in Site Assessment & Management.

Tina Girard – Dept Environment & Heritage Protection

Tina has over 18 years of experience as an environmental professional locally and internationally in consulting, operations and regulation. This has been across a diverse range of industries including mining, oil and gas, petroleum storage, airports, power generation, Department of Defence, chemical manufacturing, industrial and landfills.

John Rayner – CSIRO

John Rayner has worked in the area of contaminated site assessment and remediation since 1990 and studied many sites in Australia, New Zealand, US, UK, Kuwait, Antarctica, Alaska and Canada.  He has worked for research organizations (CSIRO, AAD), consulting and industry (BP). 

Tim Robertson – Chevron Australia

Tim has around 15 years of experience as an environmental engineer and hydrogeologist, with interest in environmental site assessment, remediation and water management.

Dr Tamie Weaver – ERM

Tamie has over 30 years of experience as a hydrogeologist and hydro-geochemist.  She has worked in the USA, Canada and Australia, focussing on the integration of physical and chemical hydrogeological data to develop robust conceptual site models, groundwater assessments and remedial strategies.  Tamie works across multiple sectors and coordinated the postgraduate Hydrogeology Program at the University of Melbourne for many years.

Andrei Woinarski – Senversa

Andrei has almost 20 years of experience in the assessment and remediation of contaminated lands here in Australia, the US and SE Asia. He enjoys developing groundwater conceptual site models and dovetailing these with risk-based and engineered solutions.
