ENM & VENM, Resource Recovery, Waste Classification, Soil Suitability, Salinity & Aggressivity — Central Coast
Proven Track Record in Fast, Accurate and Reliable ENM & VENM, Resource Recovery, Waste Classification, Soil Suitability, Salinity & Aggressivity Assessments — Central Coast
Confluence Environmental are trusted environmental consultants on the Central Coast, delivering ENM (Excavated Natural Material) assessments, VENM (Virgin Excavated Natural Material) assessments, waste classification reports, soil testing and soil classification, soil contamination testing, and Resource Recovery Orders & Exemptions (RRO/RRE). We also complete soil suitability assessments, salinity and aggressivity testing, and provide advice as experienced waste management consultants and contaminated land consultants.
Our reports are EPA-aligned, facility-ready, and recognised by councils, ensuring your soil can be reused, moved, or disposed of in compliance with NSW legislation.
When ENM or VENM is Required
A soil assessment is needed whenever soil is excavated and intended for reuse, disposal, or relocation. Councils and facilities will typically require one of the following:
ENM assessment to demonstrate natural excavated soils meet the EPA ENM Order & Exemption criteria.
VENM assessment to confirm soils are truly virgin and uncontaminated.
Waste classification where soils do not qualify as ENM or VENM.
Soil disposal advice when facilities require proof of compliance with EPA Waste Classification Guidelines.
Soil contamination testing where a site history indicates potential contaminants such as hydrocarbons, metals, or asbestos in soil.
You’ll typically need ENM/VENM or classification when:
Lodging a DA involving excavation or bulk earthworks.
Importing or exporting fill between sites.
Subdivisions or trenching works generating spoil.
Disposal of contaminated soil or mixed fill at a licensed facility.
ENM & VENM Soil Testing (EPA-Aligned)
ENM Assessments (Excavated Natural Material)
We confirm excavated soils meet the EPA ENM Order & Exemption criteria so they can be reused off-site without being tracked as waste. This includes representative soil testing, laboratory analysis, QA notes for transport, and a facility-ready letter.
VENM Assessments (Virgin Excavated Natural Material)
We confirm soils are truly virgin and uncontaminated so they qualify as VENM soil. This involves desktop review of site history, targeted sampling where necessary, and compliance documentation for receivers. VENM is typically applied to quarried or greenfield material.
Waste Classification & Soil Disposal
When soils do not qualify as ENM or VENM, we classify them under the NSW EPA Waste Classification Guidelines so facilities will accept them first time. Our waste classification reports include:
Sampling plans and laboratory results.
Classification tables (general solid, restricted solid, hazardous).
Cover letter for landfill or facility acceptance.
This process is used for contaminated soil hotspots, mixed fill, or where facilities specifically request classification before soil disposal.
Soil Suitability, Contamination & Asbestos in Soil
We provide soil suitability assessments to demonstrate soils are fit for reuse on-site (landscaping/fill) or for import. Where contamination risks are present, we complete soil contamination testing, including targeted analysis for metals, hydrocarbons, PAHs, and asbestos in soil.
Our role as contaminated land consultants ensures results are aligned with ASC NEPM and EPA guidance, giving councils and facilities confidence in your soil reuse or management plan.
Salinity & Aggressivity Testing
We protect new construction works by testing for salinity and aggressivity, ensuring compliance with AS 2870, AS 3600, and AS 2159. Parameters include pH, EC, chloride, sulfate, and resistivity, with clear design notes for engineers.

Frequently Asked Questions
Do I need an ENM or VENM soil report?
Yes — if your project involves excavation, bulk earthworks, or fill, councils and facilities will require either an ENM soil or VENM soil assessment. If soils don’t qualify, we’ll guide you through a Resource Recovery Order/Exemption (RRO/RRE) or provide a waste classification report.
Will facilities accept my contaminated soil with your report?
Yes. Our reports are facility-ready and comply with the NSW EPA Waste Classification Guidelines. We also provide documentation for soil disposal, ensuring contaminated soil or asbestos in soil is managed correctly.
What soil testing is included in ENM, VENM and waste classification?
Depending on the pathway, testing may include metals, hydrocarbons, PAHs, asbestos, and leachability. We provide targeted soil contamination testing and soil classification so your soils are accepted first time.
Can I reuse soil on site instead of disposal?
Often yes. A soil suitability assessment determines if material can be reused for fill or landscaping. If risk factors exist, we add soil testing and classification to confirm safe reuse or advise on compliant soil disposal.
