Preliminary & Detailed Site Investigations in Brisbane

As a leading provider of environmental assessments in Brisbane, Nova Group Pacific specialises in Preliminary Site Investigations (PSI) and Detailed Site Investigations (DSI). These investigations are essential for evaluating and managing contaminated land across Brisbane and South East Queensland.

They provide critical insights into site conditions, identifying potential contamination risks and supporting the development of effective, site-specific management and remediation strategies.

When Site Investigations Are Required in Brisbane

Preliminary Site Investigations are typically the first step in assessing environmental risks associated with a site. This is particularly important across Brisbane, where historical land uses, imported fill, and redevelopment can introduce contamination risks.

If potential contamination is identified, a Detailed Site Investigation is undertaken to further assess the nature, extent, and potential impacts of contamination. These investigations are often required to support development approvals, site transactions, and environmental compliance.

Preliminary Site Investigations (PSI)

Preliminary Site Investigations provide an initial assessment of environmental conditions and potential risks. They help determine whether contamination is likely to be present and whether further investigation is required.

Key Components of a PSI

Site walkovers and historical review: A site walkover and review of historical land use records are undertaken to identify potential contamination sources, past activities, and environmental risks.
Soil and groundwater screening: Preliminary sampling and screening may be carried out to detect the presence of contaminants and guide further investigation requirements..‍
Regulatory review: A PSI considers applicable Queensland environmental legislation and local council requirements to identify potential obligations for further assessment or management..

Key Components of a DSI

Detailed sampling and analysis: A structured sampling program is implemented to assess soil, groundwater, and potential contaminants across the site.
Laboratory testing : Samples are analysed by accredited laboratories to determine contaminant types and concentrations, providing reliable and defensible data.
Risk assessment: Detailed risk assessments evaluate potential impacts on human health and the environment, considering current and future land use.
Remediation planning support: Findings from the investigation inform remediation strategies, validation requirements, and site management plans.‍
