Contaminated land assessments in Sydney
Staged investigation and reporting that turns uncertainty about a Sydney site into a documented, manageable environmental risk.
We assess potentially contaminated land through site history review, targeted field investigation, sampling, laboratory analysis and risk characterisation.
The right scope depends on the suspected source, site setting, proposed land use and decision timeframe. We help project teams distinguish an initial screening question from the need for more detailed delineation, management or remediation planning.
Project context
- Former industrial and commercial sites
- Redevelopment and change-of-use projects
- Property transactions and lender due diligence
- Sites where soil, groundwater or fill materials require clarification
How we work
- Understand the history: Identify past uses, potential sources, pathways and receptors relevant to the site.
- Test the question: Design fieldwork and laboratory analysis around the contamination hypotheses that matter.
- Characterise the risk: Explain results against the intended use and set out management or next-investigation options.
What we can deliver
- Site history and desktop review
- Soil and groundwater sampling programs
- Laboratory analysis and data interpretation
- Risk characterisation against land-use criteria
- Remediation and management options

Frequently asked questions
- What can trigger a contaminated land assessment in Sydney?
- Potential triggers include historical industrial or commercial use, imported fill, unusual soil or groundwater results, a proposed change of land use, a transaction due diligence requirement or an approval condition.
- Does a contaminated land assessment always require drilling or sampling?
- Not always. A staged assessment can begin with desktop and site-history work. Intrusive investigation is planned when the available evidence indicates that sampling is needed to answer the project question.
