Any construction, redevelopment, or land purchase should not begin in New South Wales without the evaluation of environmental conditions of the site. Depending on whether the project is residential, commercial, or industrial, PSI and Detailed Site Investigation NSW will have a huge role in making local regulation compliance possible while providing protection for the environment and human health.

This post outlines those two fundamental processes. Their significance and how professional services can make these processes easier for your project in NSW will also be addressed.

What is Preliminary Site Investigation (PSI)?

Preliminary Site Investigation NSW, or PSI, is one of the early processes on assessing the environmental status of a property. It aims to identify any actual or suspected contamination that may exist on the site by looking into past and present uses of the land.

Key Objectives of a PSI

Determine Site History:

This is reviewing the previous and current activities to determine whether they pose any contamination risk. For example, old gas stations or industrial facilities ...
... retain residual contaminants in soil or groundwater .

Visual Assessment

On-site visits that identify some visual signs of contamination, including abnormal coloration of soil or chemical spill evidence.

First Level Risk Assessment

Determining if contamination risks exist by analyzing PSI outputs to ascertain if a DSI is required

PSI Outputs

The Preliminary Site Investigation NSW report provides site description, historical data, and recommendations for further investigation, if needed. At times, it is a condition precedent in submitting NSW development applications and regulatory approvals.

What is DSI?

A DSI is done when a PSI report reflects the presence of contaminants. It is a form of extensive testing and analysis to determine the fact, type, and degree of contamination.

What Is Involved in DSI?

● Sampling and Analysis:
Soil, Groundwater, and sometimes Air Sampling for Testing Contamination by Heavy metals, Hydrocarbons, or Asbestos.
● Site Characterization
Determine Extent and Distribution of Contamination to Assess Risks to Health and the Environment.
● Risk Assessment
Identify Risks Associated with Contamination and Recommends Mitigation or Remediation Strategies.
● DSI Outputs

The DSI report involves more comprehensive testing results, risk assessments, and recommendations for remediation. It provides a comprehensive understanding of the site's condition for proper informed decision-making on the development or land use.

Why PSI and DSI Are Significant in NSW

Regulatory Compliance:

NSW has strict environmental legislation on land contamination, including the Environmental Planning and Assessment Act 1979 and the Contaminated Land Management Act 1997. A failure in proper investigation can cause project delay, penalty, and liability issues.

Environmental and Public Health Protection:

Contamination that has gone unnoticed can cause harm to ecosystems, groundwater, or even air quality, which poses severe risks to communities nearby. PSI and DSI help reduce such risks.

Whether purchasing land or seeking council approvals, these investigations provide assurance to stakeholders and regulatory bodies that the site is safe for its intended use.
