TRACE Environmental offers a comprehensive range of environmental services that includes assessment of sites for potential soil and groundwater contamination, and acid sulfate soils, installation of groundwater monitoring networks and undertaking routine groundwater monitoring programs, auditing of facilities for environmental legal compliance, and preparation of applications seeking environmental approvals for new ventures or expansions of facilities.


No job is too small, or too large. Our philosophy is that each deliverable be customised to the specific requirements of each client and each engagement. If a standard approach will not deliver the best outcome, we will explore alternatives and develop a unique methodology that best meets the client’s requirements. We fully appreciate the cost imposts that environmental projects can place on companies, and always work to identify options that will minimise these costs, even where it means a reduced scope of work for TRACE.

Environmental Site Assessments

Site assessments determine the nature, extent and magnitude of soil and groundwater contamination (if any), and evaluate the risks and implications of any site contamination present. Site assessments are not only performed in response to pollution events, they are commonly performed prior to purchasing or divesting a property (pre/post- acquisition site assessment) or leasing a property (baseline environmental site assessment).


Generally an assessment may include soil sampling from soil bores or test pits, groundwater monitoring well installation and characterisation of groundwater flow conditions, and soil vapour assessment. TRACE has conducted   many Environmental Site Assessments cross Australia.


Site assessments are performed to comply with the requirements of the respective state environmental authorities, and the National Environment Protection (Assessment of Site Contamination) Measure (NEPM).    Where a client has specific requirements that differ from the focus of the NEPM, it is possible to develop a reduced brief.

TRACE routinely undertakes Environmental Site Assessments at sites where the following contaminants maybe present: 

  • Petroleum Hydrocarbons;
  • Heavy Metals;
  • PCBs;
  • PAHs;
  • Chlorinated and Brominated Compounds;
  • Perfluorinated compounds (PFCs);
  • Pesticides;
  • Cyanides;
  • Phenols; and
  • Asbestos.


Where necessary, more specialised or targeted investigations of soil or groundwater contamination can be provided.


TRACE has access to a diverse range of drilling and testing equipment, including the latest in high resolution site characterisation, such as Membrane Interface Probes (MIP), X-ray fluorescence (XRF), Flexible Liner Underground Technologies (FLUTe™) and FLUTe Activated Carbon Technique (FACT), amongst others. This ensures that we always recommend and use the most appropriate device for each individual assignment.


Supporting the field investigations
is a team of highly skilled and experienced geologists, environmental scientists, and engineers, who use state-of-the-art computational tools and models to map contaminant plumes, predict the fate and transport of contamination, and assess on-site and off-site risk to human and ecological receptors.

Waste Classification and Disposal

TRACE specialises in waste classification, management and disposal to ensure our clients’ waste management practices are in compliance with regulatory requirements, which vary by jurisdiction.

Whether it is classification and disposal of contaminated soils, groundwater, industrial waste, or providing assistance to acquire waste disposal permits and/or other waste monitoring requirements, TRACE has the expertise and experience to ensure trouble free and cost effective waste management.

Health and Ecological Risk Assessments

Risk assessment is a scientific methodology endorsed in Australia 
and internationally to assess and manage site contamination.
Risk assessment can be a qualitative and/or quantitative  estimate of risks to human and ecological receptors as a result of site contamination.

Detailed risk assessment provides enormous advantages for owners of sites with contamination, which can be used to ensure that the remediation goals established for the site properly account for the risks present, and ensure that máximum remedial benefit is achieved for the mínimum expediture necessary to make the site suitable for the proposed land use.

Remedial Action Plans

Remedial Action Plans (RAPs) document the proposed remediation strategy and clean-up criteria for contaminated land. It is a detailed operational manual which discusses
 the selection and appropriateness of 
the remediation method, and outlines 
the validation sampling and analysis plan, quality assurance and quality control procedures, and relevant regulatory requirements.


In addition, site environmental management plans, contingency plans, an occupational health and safety plan, and a community consultation plan may be required to ensure site remediation is managed in an environmentally acceptable manner. 

RAPs are usually required, as a condition of approved development application, when site assessments indicate that contamination is present about guideline levels for the proposed land use. Usually a Site Auditor, accredited by the Environment Protection Authority (EPA) is appointed to review the RAP, and oversee the validation program. RAPs are also required to address a clean up order or notice from EPA.


Planning authorities require commonly require RAPs to be submitted along with development applications, to ensure the proposed clean-up strategy and criteria are appropriate for the future use of the site.     


Having experienced remediation engineers and scientists undertake a thorough assessment of the most suitable and practical remedial options during preparation of the RAP, can save the client significant expense in minimising the scope and time of remediation works, and avoiding costly delays in obtaining development approval or auditor sign-off.
