Brownfield sites are previously developed lands often impacted by industrial or commercial activities. Because of strict regulations outlined in the Contaminated Sites Act 2003, they present unique challenges and opportunities for redevelopment.
Transforming these sites requires a nuanced approach that balances environmental responsibility with urban growth. At West Soil & Water, we specialise in comprehensive brownfield remediation services, ensuring that redevelopment projects proceed safely, sustainably and in compliance with the Act.

Brownfields are parcels of land that were previously developed but are now underused, vacant or derelict. These sites may be affected by real or perceived contamination, typically due to past industrial, commercial or agricultural activities.
In Western Australia, brownfields are commonly found in urban and semi-rural areas where urban renewal is taking place on former industrial land. While they may present environmental challenges, brownfields also offer valuable opportunities for development, helping reduce urban sprawl and revitalise underutilised land.
However, before redevelopment can proceed, these sites often undergo environmental assessment, risk evaluation and, where necessary, remediation. Whilst a brownfield site it not automatically hazardous, proper due diligence is required under WA’s Contaminated Sites Act 2003.
Treatment of a brownfield site is typically required when environmental assessments either confirm or strongly suspect contamination. Under the Act, certain levels of contaminants trigger a legal obligation to investigate further and, if necessary, implement a remediation strategy.
This could be when:
A Phase I or II Environmental Site Assessment identifies contamination above acceptable thresholds
The site is classified by DWER as “Contaminated – Remediation Required” or “Possibly Contaminated – Investigation Required”
There is a planned change in land use, such as redevelopment for residential, childcare or mixed-use zoning
Contaminants are found to be migrating offsite, affecting neighbouring properties, surface water or groundwater
A condition of planning approval or subdivision requires remediation before development can proceed
Early identification of these triggers helps developers avoid delays and ensures that remediation is integrated into project timelines. Practitioners with experience in contaminated land management, such as West Soil & Water, will assist you in determining whether remediation is required.
Prior to any development, West Soil & Water will assist you by providing:
Understanding the extent and nature of contamination is the first step in any remediation project. We carry out:
Preliminary Site Investigations (PSI): Reviewing historical data and conducting initial site inspections to identify potential contamination.
Detailed Site Investigations (DSI): Comprehensive sampling and analysis of soil and groundwater to delineate contamination.
Our contaminated land investigations are conducted in accordance with the National Environment Protection (Assessment of Site Contamination) Measure (NEPM) guidelines.
We perform human health and environmental risk assessments to evaluate the potential impacts of any identified contaminants. This process informs the development of appropriate remediation strategies.
Based on assessment findings, we develop Remediation Action Plans (RAPs) that outline how the project should address contamination. Strategies may include methods such as:
Excavation and disposal: Removal of contaminated soil for off-site treatment or disposal.
In-situ treatment: On-site treatment of contaminants using chemical, biological or physical methods.
Containment: Installation of barriers to prevent contaminants from spreading.
We will oversee the implementation of our plans and activities to ensure they meet regulatory requirements and project objectives.
Navigating the regulatory landscape is critical in brownfield development. We can assist you in engaging with the Department of Water and Environmental Regulation (DWER), facilitating approvals where necessary and ensuring all reporting obligations are met.
