Commercial Decontamination Services

Commercial & Industrial Decontamination Services

Excavator working on a large-scale remediation site — Commercial and industrial remediation, from a single contaminated site to full mine closure.

Alongside our residential and small business services, Delta Environmental provides a broader range of commercial and industrial decontamination and environmental remediation capabilities for developers, mining operators, councils, insurers and industrial property owners across Australia. These larger-scale services are coordinated with accredited environmental consultants and laboratories, and are scoped individually given the technical and regulatory complexity involved.

Whether you are managing a contaminated development site, a mine approaching closure, or an industrial property being prepared for sale, the sections below outline the specific capabilities we draw on, either directly or through our environmental consulting partners.

Site & earthworks

Site Remediation & Earthworks

01Soil Remediation Services

Contaminated soil, whether from historical industrial use, fuel or chemical spills, or heavy metal contamination, can be treated in place or excavated for off-site disposal or treatment depending on the contaminant and site conditions. We scope soil remediation around what a site-specific assessment identifies, rather than a one-size-fits-all excavation.

02Dewatering Services

Construction, excavation and remediation work below the water table often requires controlled dewatering to keep a site workable and safe. Extracted water is managed and, where contaminated, treated before discharge or disposal in line with local water authority and EPA requirements.

03Construction Site Remediation

Pre-construction contamination assessment and remediation is increasingly a condition of development approval, particularly on sites with a prior industrial or agricultural history. We coordinate assessment, remediation and validation reporting to help projects meet council and planning requirements.

04Acid Sulfate Soil Management

Common in coastal and estuarine areas of Australia, acid sulfate soils release sulfuric acid when disturbed and exposed to air, with the potential to damage waterways, concrete and steel infrastructure if left unmanaged. Development in these areas typically requires a specific acid sulfate soil management plan, which we help scope and implement.

Mining & resources

Mine Site & Resources Sector Services

05Specialised Mine Site Cleaning (High-Risk Environments)

Mine site decontamination often involves remote locations, confined spaces and elevated exposure risks that require additional planning, PPE and logistics beyond a standard commercial job. Our technicians follow site-specific safety protocols developed in consultation with mine operators for these higher-risk environments.

06Mine Rehabilitation & Remediation

Post-closure mine rehabilitation covers land reshaping, contamination remediation, erosion control and revegetation to meet regulatory closure requirements. We support these programs alongside environmental consultants managing the broader closure plan, from contamination remediation through to final validation.

Water & vapour

Water, Vapour & Emerging Contaminant Services

07Water Treatment Services

Industrial wastewater, contaminated stormwater and groundwater extracted during remediation often need treatment before discharge or reuse. Treatment approaches are matched to the specific contaminants present and the discharge or reuse standard that applies to the site.

08Biological Leachate Remediation (BLR)

Leachate from landfills and some industrial sites can be treated using biological processes that break down organic contaminants before discharge. This approach is typically applied where leachate volumes and contaminant profiles make biological treatment more practical than purely physical or chemical methods.

09Vapour Remediation Services

Volatile contaminants in soil or groundwater can migrate as vapour into overlying buildings, a pathway known as vapour intrusion. Depending on the site, this is managed through sub-slab depressurisation systems, vapour barriers, or source remediation, guided by a site-specific vapour intrusion assessment.

10PFAS Remediation Solutions

Per- and polyfluoroalkyl substances, commonly known as PFAS, are persistent chemicals found at some sites with a history of firefighting foam use or certain industrial processes. PFAS remediation typically involves a combination of assessment, containment and treatment technologies such as activated carbon or ion exchange, scoped to the specific site and regulatory requirements involved.

Consulting & property

Environmental Consulting & Property Remediation

11Resource Recovery Solutions

Where contaminated or excess material can be safely treated, recycled or reused rather than sent to landfill, we look for resource recovery options as part of the remediation plan, reducing disposal costs and environmental impact where the contamination profile allows it.

12Contaminated Land Consulting Services

Phase 1 and Phase 2 environmental site assessments establish whether a property carries contamination risk from its history and current use, supporting due diligence for property transactions, planning approvals and financing. We coordinate these assessments with accredited environmental consultants.

13Contaminated Groundwater Consulting Services

Groundwater contamination requires monitoring bore installation, plume delineation and a remediation strategy tailored to the contaminant and local hydrogeology. We work alongside hydrogeological consultants to scope and implement groundwater monitoring and remediation programs.

14Environmental Management Consulting

Beyond one-off remediation, some clients need broader environmental management advice, covering compliance obligations, environmental management plans and ongoing monitoring programs. We can coordinate this consulting support alongside any physical remediation work required.

15Contaminated Industrial or Commercial Property Remediation

Decommissioning an old industrial site or preparing a commercial property for sale or redevelopment often means addressing legacy contamination such as hydrocarbons, asbestos or heavy metals across the whole property, not just a single work area. We scope and manage these larger remediation programs end to end.

How it works

How We Scope Commercial & Industrial Projects

Initial consultation. We discuss the site, its history and your regulatory or commercial drivers before proposing next steps.

Assessment & scoping. Site assessment, coordinated with environmental consultants where needed, defines the extent and nature of the work required.

Remediation & validation. Remediation is carried out to the agreed scope, with independent validation testing confirming the result.

Reporting & sign-off. You receive full documentation suitable for regulators, financiers, insurers or future buyers.

Why choose Delta

One Point of Contact for Complex Sites

Coordinated, not fragmented

We coordinate specialist environmental consultants and laboratories so you deal with one point of contact rather than multiple disconnected contractors.

Independent validation

Validation testing and reporting is carried out independently of the remediation team, consistent with every service we offer.

Scoped to the site

Commercial and industrial jobs are priced and planned around a site-specific assessment, not a standard package.

Australia-wide capability

From metro industrial sites to remote mine locations, our network and consulting partners extend across the country.

Not sure which service applies?

Commercial and industrial contamination rarely fits neatly into one category. Call us and describe the site and its history, and we will advise which of the services above are relevant and how to scope next steps.

Our guarantee

What You Can Expect When You Book Delta

Booking your commercial or industrial site with an unfamiliar company can feel like a leap of faith, so we keep our side of the arrangement simple and transparent. You get a clear, itemised scope of works before anything begins, a fixed appointment window rather than a vague all-day slot, and a single point of contact for the life of the job rather than being passed between call centres.

If a job turns out to be larger or more complex once work is underway, we explain why, put any change in writing, and get your sign-off before proceeding. There are no surprise line items on the final invoice.

Straightforward, no-pressure quotes

We quote based on what your property actually needs, not a one-size-fits-all package. If a lighter touch will do the job safely, that is what we will recommend.

Frequently asked questions

Some services, such as site remediation and water treatment, are delivered directly by our teams. More specialised technical work, such as contaminated land or groundwater consulting, is coordinated with accredited environmental consulting partners so you still deal with a single point of contact.

PFAS refers to per- and polyfluoroalkyl substances, a group of persistent chemicals historically used in some firefighting foams and industrial processes. Because they do not break down easily in the environment, PFAS-affected sites typically require specific assessment and treatment technologies rather than standard remediation methods.

It is a site-specific plan for managing soils that release sulfuric acid when disturbed and exposed to air, common in coastal and estuarine parts of Australia. These plans are often a condition of development approval in affected areas.

Yes. Contaminated land consulting, including Phase 1 and Phase 2 environmental site assessments, supports due diligence before purchasing or redeveloping a property with a potentially contaminated history.

Yes, including specialised cleaning in high-risk mine environments and mine rehabilitation and remediation work as part of closure planning, working within the site-specific safety protocols each operation requires.
