Preliminary Site Investigation

Summary

A Preliminary Site Investigation (PSI) is a non-intrusive, early-stage assessment used to identify whether a site has the potential for contamination based on historical use and observable conditions. It helps determine if further investigation is required before development, acquisition, or regulatory approval.

Definition

A Preliminary Site Investigation (PSI) is the first stage of a formal site assessment, involving a desktop review of historical land uses, environmental records, and an initial site inspection. The goal is to determine whether there is a potential for contamination that warrants further investigation. PSIs follow regulatory guidelines to assess site risk without intrusive testing at this stage.

Why It Matters

A PSI is essential for identifying potential contamination risks early, allowing for informed decision-making and budgeting in development or remediation projects. By detecting risks upfront, a PSI can prevent costly surprises during later stages, streamline the approvals process, and ensure environmental compliance.

When It’s Required

• Planning & Development: Before submitting a development application on a site with potential contamination.‍
• Property Transactions: To assess environmental risk prior to sale or lease.‍
• Regulatory Requests: When councils or environmental agencies require baseline environmental information.‍
• Risk Management: For operational sites undergoing expansion or change of use.
