Environmental Site Assessment & Testing

Environmental Due Diligence, Compliance & Site Management

BHM Geotechnical provides practical environmental solutions to help clients identify contamination risks, understand site constraints, and meet environmental compliance requirements. The services include:

01

Preliminary Assessments & Environmental Due Diligence

Understanding a site's history is often the first step in identifying environmental concerns before development or acquisition.

Our investigations may include

  • Preliminary Site Investigations (PSI / Phase 1)
  • Preliminary Site Investigations (Phase 1)
  • Historical land use reviews
  • Site inspections and assessments
  • Contamination risk identification
  • Pre-purchase due diligence

These assessments identify potential environmental constraints and determine whether a detailed investigation is required.

02

Detailed Investigations, Testing & Validation

When potential contamination risks are identified, detailed investigations provide the information required for effective environmental management.

Services may include

  • Detailed Site Investigations (DSI / Phase 2)
  • Detailed Site Investigations (Phase 2)
  • Soil and groundwater sampling
  • Laboratory testing and analysis
  • Validation assessments
  • Waste classification and material suitability assessments

The findings support remediation decisions, regulatory compliance, and future development planning.

03

What a Proper Environmental Investigation Should Identify

Environmental investigations should identify contamination risks, affected environmental media, potential exposure pathways, and whether further assessment or management is required.

Our investigations may identify

  • Historical contaminating activities
  • Areas of environmental concern
  • Contaminants of potential concern (COPCs)
  • Potentially affected soil and groundwater
  • Human and ecological receptors

The findings help determine whether further investigation, remediation, validation, or environmental management is required.

    Understanding Common Environmental Assessment Triggers in South Australia

    In South Australia, environmental investigations may be required where land is proposed to be changed to a more sensitive use, subdivided for sensitive use, redeveloped from potentially contaminating land uses, or assessed as part of acquisition due diligence.

    Environmental investigations may be undertaken with consideration of relevant South Australian planning requirements, the PlanSA Site Contamination Assessment Scheme, Practice Direction 14, ASC NEPM guidance, and EPA South Australia requirements where applicable.

    Frequently Asked
    Questions

    What is an environmental investigation?

    An environmental investigation assesses a site for contamination, hazardous materials, and environmental constraints that may affect development, acquisition, or ongoing land use. It may involve historical reviews, site inspections, soil and groundwater sampling, laboratory testing, and detailed environmental reporting.

    When do I need an environmental site investigation?

    Environmental site investigations are commonly required before property purchases, redevelopment, construction projects, or when contamination is suspected. They help identify potential environmental risks early, support planning approvals, and prevent unexpected remediation costs or project delays.

    What is a Preliminary Site Investigation (PSI)?

    A Preliminary Site Investigation (Phase 1) involves reviewing historical land use, environmental records and conducting a site inspection to identify potential contamination risks. The findings determine whether further investigations, such as a Detailed Site Investigation, are required.

    Why is environmental due diligence important before purchasing land?

    Environmental due diligence helps identify potential contamination liabilities, site constraints, and future remediation requirements before a property transaction is completed. Understanding environmental risks early supports informed investment decisions and helps avoid unexpected costs after acquisition.

    When is a PSI required in South Australia?

    A Preliminary Site Investigation may be required when land is proposed to be changed to a more sensitive use, subdivided, redeveloped from potentially contaminating land uses, or assessed as part of environmental due diligence. Requirements vary depending on the site, proposed development, and planning pathway.

    What happens if contamination is found?

    Where contamination is identified, additional investigation may be required to determine its nature, extent, and potential risks. Depending on the findings, this may lead to a Detailed Site Investigation, remediation planning, validation assessment, or ongoing environmental management.
