Reimagining Contaminated Land Remediation in Victoria

Reimagining Contaminated Land Remediation in Victoria

Innovation, Regulation, and Sustainability in 2025

Land contamination remains one of the most complex environmental challenges facing Victoria. From legacy industrial sites to emerging contaminants like PFAS, the need for effective, adaptive, and sustainable remediation strategies has never been greater. In 2025, the sector is undergoing a transformation, driven by regulatory reform, technological innovation, and a renewed focus on long-term environmental outcomes.

The Regulatory Landscape: A New Era of Accountability

Victoria’s Environment Protection Act 2017 continues to shape how contaminated land is managed. The EPA’s updated guideline for creating a Clean Up Plan (Publication 5004, August 2025) sets out clear expectations for remediation action plans. These plans must be:

  • Site-specific, informed by detailed investigation and risk assessment.
  • Designed to remediate contamination so far as reasonably practicable.
  • Structured to minimise harm to human health and the environment.

Environmental auditors and consultants alike. are now required to align with these guidelines, the Environment Reference Standards (ERS), and any relevant compliance codes. This ensures consistency and accountability across remediation projects.

PFAS and Emerging Contaminants: Navigating New Standards

The release of PFAS National Environmental Management Plan (NEMP) Version 3.0 in March 2025 has reshaped how PFAS impacted materials are handled. Key updates include:

  • New guideline values for PFAS in soil, water, and biosolids.
  • New frameworks for risk-based reuse of contaminated materials.
  • Ecological guidelines for wildlife exposure and residential land use thresholds.

These changes have had immediate implications. For example, a regional Victorian project involving PFAS impacted biosolids had to pivot mid-remediation to meet new reuse thresholds, highlighting the need for staged and flexible remediation planning.

Meanwhile, a national review of asbestos in recycled materials is challenging the “zero tolerance” approach, advocating for risk-based thresholds that balance safety with practicality.

Best Practices in Remediation: Adaptive, Sustainable, Collaborative

Remediation in Victoria is increasingly guided by adaptive strategies that evolve with site understanding. According to Dr. Louise Cartwright, a leading contaminated land auditor, successful projects now incorporate:

  • Early options screening to avoid premature design lock-in.
  • Contractor experience and sustainability assessments.
  • Carbon impact and material reuse considerations.

Projects are also embracing collaborative models, integrating stakeholders from government, industry, and community to ensure transparency and shared outcomes.

Challenges and Opportunities Ahead

Despite progress, challenges remain:

  • Regulatory variation across states can create inefficiencies for national developers.
  • Delays in approvals can stall critical remediation timelines.
  • Legacy contaminants like asbestos require nuanced, risk-based approaches.
  • Remote site logistics demand innovative solutions and robust stakeholder engagement.

Yet, these challenges are driving innovation. The sector is exploring in-situ treatment technologies, data-driven risk assessments, and nature-based solutions to deliver remediation that is not only effective but regenerative.

Final Thoughts

Victoria’s contaminated land sector is at a pivotal moment. With evolving regulations, emerging contaminants, and a push for sustainability, environmental management companies must stay agile, informed, and collaborative. By embracing adaptive planning, leveraging new technologies, and aligning with the latest EPA guidelines, we can turn contaminated sites into opportunities for renewal and resilience.
