Preliminary & Detailed Site Investigations in Melbourne

Site Investigation Services in Melbourne

Nova Group Pacific specialises in Preliminary Site Investigations (PSI) and Detailed Site Investigations (DSI) across Melbourne, supporting contaminated land assessment, redevelopment, environmental due diligence, and planning requirements.

These investigations provide critical insights into site conditions, helping identify contamination risks, assess environmental constraints, and support the development of practical remediation and site management strategies tailored to project requirements.

When Site Investigations Are Required in Melbourne

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

Where potential contamination is identified, a Detailed Site Investigation may be required to further assess the nature, extent, and potential impacts of contamination. These investigations are commonly undertaken to support planning permit applications, redevelopment projects, site transactions, environmental due diligence, and regulatory compliance obligations.

Preliminary Site Investigations (PSI)

Preliminary Site Investigations provide an initial assessment of environmental conditions and potential contamination 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, previous site activities, and environmental risks associated with the property.
Soil and groundwater screening: Preliminary soil and groundwater sampling or screening may be undertaken to identify potential contaminants and help determine whether further investigation is required.
Regulatory review: A PSI considers applicable EPA Victoria requirements, Victorian environmental regulations, planning permit conditions, and local council requirements to identify potential obligations for further assessment or management.

Preliminary Site Investigation Services in Melbourne

At Nova Group Pacific, our Preliminary Site Investigation services are tailored to the specific conditions and requirements of each project.

We provide:

Comprehensive Site Assessments

Detailed site walkovers and environmental assessments to identify contamination risks, environmental constraints, and potential site management considerations.

Environmental Sampling

Soil and groundwater sampling using appropriate field and laboratory methodologies to support preliminary environmental risk assessments and contamination screening.

Regulatory Expertise

Guidance on EPA Victoria requirements, contaminated land frameworks, and planning obligations to help support informed project decision-making and regulatory compliance.

Detailed Site Investigations (DSI)

Detailed Site Investigations are undertaken where a Preliminary Site Investigation identifies potential contamination risks requiring further assessment. These investigations provide a comprehensive understanding of contamination characteristics, environmental risks, and site suitability considerations.

Key Components of a DSI

Detailed sampling and analysis: Structured soil and groundwater sampling programs are implemented to assess contamination conditions, contaminant distribution, and potential environmental impacts across the site.
Laboratory testing: Samples are analysed by National Association of Testing Authorities (NATA) accredited laboratories to determine contaminant types and concentrations and provide accurate, defensible environmental data.
Risk assessment: Detailed risk assessments evaluate potential impacts on human health, groundwater, and the environment while considering current and proposed land use scenarios.
Remediation planning support: Findings from the investigation help inform remediation strategies, validation requirements, environmental management measures, and future site planning considerations.
