What is an Environmental Site Assessment (ESA)?

An environmental site assessment is a systematic investigation to determine if land is contaminated (usually undertaken by a suitably qualified environmental consultant).These assessments are essential for:

  • Land development projects requiring planning permit approval
  • Property purchase / divestment where environmental due diligence is critical
  • Property leasing to understand a property’s contamination status prior to the commencement of a lease agreement
  • Environmental audits for planning proposals involving a sensitive use
  • Environmental duties, i.e. the General Environmental Duty (GED) or Duty to Manage

Our Environmental Site Assessment Services

Preliminary Site Investigation (or Phase 1 Environmental Site Assessment)

Our preliminary site investigation (PSI) provides a comprehensive desktop study and site inspection to identify potential contamination concerns (generally without physical sampling).
What we investigate:

  • Historical land use analysis from aerial photography and title records
  • Previous industrial, commercial, or agricultural activities
  • Potential contamination sources on neighboring properties
  • Regulatory database searches and review
  • Site walkover inspection and visual assessment

Deliverables:

  • Initial conceptual site model (CSM) and risk assessment
  • Clear recommendations for next steps
  • Regulatory compliance confirmation
  • Timeline and cost estimates for any required additional site investigation work

Detailed Site Investigation (or Phase 2 Environmental Site Assessment)

When a PSI indicates the presence of land contamination, a detailed site investigation (DSI) involves additional assessment to delineate the type, levels, and extent of that contamination.

Our investigation approach includes:

  • Strategic design and sampling of environmental media based on contamination type and risk
  • Laboratory analysis using accredited facilities
  • Comparison of the resulting data against applicable screening criteria

Expert analysis and reporting:

  • Contamination extent mapping
  • Human health and environmental risk assessment
  • Remediation feasibility and cost estimates
  • Regulatory compliance pathways
  • Development impact assessment
