PSI

The Preliminary Site Investigation (PSI) is an initial environmental assessment undertaken to identify potential contamination risks on a site. It involves a review of historical land use, site conditions, and available data to determine whether further detailed investigation is required.

Key Components

• Desktop Review: Analysis of historical records, aerial imagery, site plans, and regulatory databases.
• Site Inspection: Visual assessment to identify potential contamination sources or areas of concern.
• Risk Identification: Identification of current and historical activities that may have caused contamination.
• Recommendations: Guidance on whether further investigation (such as a Detailed Site Investigation) is required.

A PSI is a critical first step in contaminated land management, helping to inform due diligence, support planning approvals, and guide risk-based decision-making for development projects.
