Waste Classification

Excavated soil stockpiles at an industrial site awaiting waste classification

Classify excavated material before your project stalls

Where can the excavated soil go, and what will it cost to move it there? Waste classification uses site information, representative sampling and laboratory results to determine how material should be managed, reused or disposed of; helping your team plan excavation works and avoid unexpected disposal costs.

Avoid treating every load as the worst case

Excavated soil cannot be directed to the right reuse or disposal pathway without understanding its origin and contamination status. An incorrect assumption can increase cost, interrupt earthworks, or send material to an unsuitable destination.

Geotesta reviews the site context, prepares an appropriate sampling program and coordinates laboratory analysis to classify the material for disposal or reuse. Geotesta provides state-specific classification such as ENM or VENM or Waste Category, and assesses the material against the applicable criteria and provides the supporting evidence needed before it is moved.

Investigation Methods

The scope depends on the material source, excavation volume, site history, applicable project requirements. Classification should be completed early enough to inform stockpile management, transport planning, reuse options and disposal costs before excavation begins.

Desktop Review

Site history, previous reports and the source of the material are reviewed to identify likely contaminants and classification constraints.

Sampling plan

Representative sampling locations and quantities are selected around the stockpile, excavation area, material type and required level of confidence.

Field Sampling

Soil samples are collected, described and documented so laboratory results can be linked to the material being assessed.

Laboratory Analysis

Samples are analysed for contaminants relevant to the site history, material source and required classification pathway.

Classification Advice

The results are assessed to determine how the material can be managed, including whether further sampling or hot spotting is recommended.

State Specific Waste Classifications

Where these classifications are required, Geotesta can assess the available evidence against the project requirements once the scope has been confirmed.

Connected field sampling and laboratory support

Geotesta keeps sampling, analysis and interpretation connected, while the team explains what the classification means for handling, transport and the next construction decision. This depth of expertise and dependable, coordinated service is why commercial organisations and government bodies across Australia continue to rely on Geotesta.

Frequently Asked Questions

Need to classify soil before it leaves site?

Waste classification determines how excavated soil or other material should be managed, transported, reused or disposed of, based on its origin, characteristics and contamination status.

Complete classification before large-scale excavation or transport begins, so stockpile areas, truck movements, destinations and disposal allowances can be planned.

Australian states and territories use different classifications and criteria for excavated soil and natural material. ENM and VENM are classifications used in New South Wales, while other jurisdictions apply their own terminology, evidence requirements and assessment criteria.

No. Eligibility depends on the material’s source, site history, level of disturbance, contamination results and the requirements of the relevant state or territory. Geotesta assesses the material against the criteria that apply to the project location and proposed reuse or disposal pathway.

Sampling depends on excavation volume, material variability, site history, stockpile arrangement, suspected contaminants, and the level of confidence required.

Yes. Geotesta can prepare a Waste Designation submission on your behalf for submission to the Victorian EPA to potentially reclassify waste soils.
