The Remediation Of Contaminated Soil

What Is Soil Remediation?

Soil remediation is the process of removing or neutralising contaminants in soil to restore land to a safe, usable condition.​ Site remediation, while similar, can also involve groundwater and surface contamination.​

Wollongong’s industrial history, including its steel, mining, and port heritage, has led to contaminated land being a common issue in the region.

Common Types of Soil Contaminants

  • Asbestos fibres (especially in older residential and industrial sites)​
  • Petroleum hydrocarbons (from fuel storage tanks, service stations, and industrial facilities)​
  • Heavy metals such as lead, arsenic, and chromium​
  • Volatile organic compounds (VOCs) from manufacturing or chemical use​
  • Pesticides and chemicals​ left from agricultural land use

Why Does Wollongong Soil Remediation Matter?

Simply, soil remediation SHOULD matter to every land owner because of the legal consequences of ignoring it. You may suffer financially or be held responsible for any health-related and community-facing problems.

Human Health and Environmental Risk

  • Soil contaminants can leach into groundwater, affecting drinking water and local ecosystems​, impacting your wider community
  • Exposure to hazardous materials such as asbestos or heavy metals poses the risk of severe health issues to workers, residents, and future occupants​
  • Children and older, or vulnerable populations, are at the greatest risk from contaminated land​, via inhalation, ingestion or skin contact

Regulatory and Legal Obligations in NSW

  • In NSW, contaminated land is regulated under the Contaminated Land Management Act 1997 and the EPA’s guidelines​
  • If a Wollongong land owner suspects contamination, it is highly recommended that they seek professional assessment early in any development process
  • Councils and planning authorities require documented confirmation that remediation has taken place before issuing approvals for occupation or development​
  • Failure to address contamination can result in fines, Clean-Up Notices, or the loss of development permits​
  • Developers and landowners may face litigation if contamination is not managed​

Financial and Property Value Implications

  • Property developers, builders, and commercial landowners are often surprised at the cost of remediation vs. the cost of inaction
  • Contaminated land has a lower market value and can put off future buyers
  • Remediation can improve long-term returns on the investment​ by opening up development possibilities
  • Delays caused by unresolved contamination issues are often more costly than the remediation itself

Site Investigation and Soil Testing

  • Samples undergo accredited Laboratory analysis to identify the types and concentrations​ of any contaminant
  • Risk assessment to plan the appropriate course of action​

Contaminated Soil Removal and Disposal

  • All waste is taken to certified disposal or treatment facilities​
  • Waste tracking is documented to comply with regulations

  • Soil washing
    • Using water or chemical solutions to extract contaminants from soil particles​

Groundwater Monitoring

  • Groundwater monitoring helps to identify the extent of contamination and is used to track progress during remediation

The 4-Step Soil Remediation Process

This section provides an overview of the Wollongong site remediation process, so you can understand what is happening in each phase.

Step One: Site Assessment and Investigation

  • During a site inspection, we review site history and prior land use to identify likely contamination sources
  • We undertake soil sampling and send the samples for testing
  • Laboratory analysis will confirm contaminant types, concentrations, and the extent of affected areas​
  • We prepare a Site Investigation report as required by the EPA​

Step Two: Remediation Action Plan

  • Develop a Remediation Action Plan (RAP) based on the results of our site visit and testing results
  • Use the most appropriate treatment methods for the specific contaminants and site conditions​
  • Set remediation goals, including target contaminant levels, to enable job sign-off​
  • Submit the RAP for review by the relevant authorities or the client’s environmental representatives

Step Three: Remediation Works

  • Our team, plus any equipment or machinery required arrive on site
  • Work to the agreed remediation methods, whether excavation, treatment, or a combination​
  • Manage all waste streams in accordance with EPA and local council requirements​
  • Professional contractors keep projects on schedule, within scope, and within budget. It is essential that you engage licensed operators, particularly for asbestos-related work, to ensure legal compliance

Step Four: Validation and Sign-Off

  • Collect soil samples post-remediation to confirm contaminant levels are as expected
  • Prepare documentation of test results, methods used, and outcomes achieved​
  • Submit validation documentation to the EPA, council, or relevant local authority
    • This step is essential to gain approval for future development
  • Obtain formal sign-off confirming the site is suitable for its intended use​.
