Who It's For

Do you need contaminated land services?

Homeowners & property developers

Homeowners and property developers must do their due diligence before starting construction on a new piece of land to ensure they adhere to building best practices. BBN works alongside you to guarantee this, from an initial site investigation to remediation and recording the contaminated materials on necessary contaminated land registers.

Projects of all scales

BBN has worked on projects of all scales, from residential properties to large commercial developments, so there's nothing our experienced team can't handle. We have several years of experience within the industry and pride ourselves on implementing exceptional occupational hygiene and safety solutions.

Know Your Site

Common contaminants on Australian sites

Contamination is rarely visible from the surface. It usually reflects a site's history: past industrial, commercial or agricultural uses that left hazardous substances behind in soil and groundwater. These are the contaminants we most commonly investigate:

Asbestos

Buried asbestos containing material from demolished buildings, old fill or illegal dumping. A frequent finding on sites developed before 1990.

Heavy metals

Lead, arsenic, cadmium, chromium and mercury from industrial activity, old paints and imported fill material.

Petroleum hydrocarbons

Fuels and oils from service stations, underground storage tanks, workshops and machinery yards. One of the most common sources of soil and groundwater contamination.

PFAS

Per- and polyfluoroalkyl substances, historically used in firefighting foams around airports, defence sites and fire training grounds.

Pesticides & herbicides

Organochlorine pesticides from former orchards, market gardens, cattle dip yards and historical termite treatment around building footings.

Solvents & industrial chemicals

Chlorinated solvents and other chemicals associated with dry cleaners, former gasworks and manufacturing sites.

When To Act

When do you need a contaminated land assessment?

Contaminated land obligations are governed by state and territory legislation, and an assessment is often a formal requirement, not just good practice. Common triggers include:

Buying or selling land: due diligence before purchase protects you from inheriting liability for contamination caused by previous owners.
Development applications: councils commonly require a Preliminary or Detailed Site Investigation where a site's past use is potentially contaminating.
Change of use: converting industrial or agricultural land to residential or childcare use triggers stricter assessment criteria.
Suspect material found during works: unexpected odours, staining, buried waste or suspected asbestos uncovered during excavation or demolition.
Underground fuel tanks: removing or decommissioning underground storage tanks requires validation that surrounding soil is clean.
Taking soil off site: excavated soil must be classified before it can be lawfully transported and disposed of.

How does Queensland regulate contaminated land? (EMR, CLR and SQPs)

Queensland manages contaminated land under the Environmental Protection Act 1994 through two public registers. The Environmental Management Register (EMR) lists land where a notifiable activity has been carried out, or where contamination is known or suspected. The Contaminated Land Register (CLR) lists land that is contaminated and requires remediation or management.

Checking both registers is the first step in any Queensland transaction or development. An EMR or CLR listing doesn't necessarily stop a sale or development, but it signals risk that lenders, insurers and councils will usually require to be assessed before they proceed. Assessment reports must be prepared by a Suitably Qualified Person (SQP), with independent review provided by approved auditors. For South East Queensland's development pipeline, where brownfield sites are increasingly the only sites left, early EMR/CLR screening is the cheapest risk control available.

Our Process

How BBN can help: our contaminated land management services

BBN Consulting can perform an Environmental Due Diligence (EDD) assessment to ensure you adhere to your environmental obligations. This is a simple way to determine if the land is safe to be built on. We can also provide an Environmental Site Assessment (ESA), which is completed in five stages:

01

Preliminary Site Investigation (PSI)

A critical step in the development or remediation of a property, gathering information about the site and its surroundings to identify any potential environmental or geotechnical hazards or risks. Typically involves a thorough review of available data and records, as well as field assessments and testing.

02

Detailed Site Investigation (DSI)

A more comprehensive and in depth investigation than a PSI, conducted after potential hazards or risks have been identified. Designed to gather more detailed and specific information, and may be required as part of development, remediation or to satisfy regulatory requirements.

03

Remediation Action Plan (RAP)

Once we've completed our inspection, we'll compile a detailed report of our findings, advising you on your next steps.

04

Validation Sampling & Report

This document details your action plan so you can get started on your build confidently.

05

Classification

Our team will help you with soil and waste classification, keeping you compliant with the latest waste guidelines.

FAQs

Everything you need to know about contaminated land management.
What is contaminated land?
Under Queensland's Environmental Protection Act 1994, contaminated land is land where a notifiable activity has occurred, or where hazardous substances are present at levels that could harm human health or the environment. It's tracked through the state's EMR and CLR registers.
How do I find out if the land is contaminated?
Start with an EMR/CLR search, then a Suitably Qualified Person can assess the site. BBN runs both — an Environmental Due Diligence assessment to check your obligations, and if needed, a full investigation and Remediation Action Plan to clear a path forward.
What is the best way to manage contaminated land?
Start with a Preliminary Site Investigation to screen for risk. If it flags a concern, a Detailed Site Investigation follows. BBN's in-house lab (Aether-01) and drone/LiDAR site capture (EagleEye) mean you get that answer in days, not weeks.
What is the difference between a PSI and a DSI?
A Preliminary Site Investigation (PSI) is a desktop and walkover study with no soil sampling. A Detailed Site Investigation (DSI) is the intrusive next stage — boreholes, sampling and lab analysis — undertaken only when the PSI flags a credible concern that needs quantifying.
What are the EMR and CLR in Queensland?
The Environmental Management Register (EMR) and Contaminated Land Register (CLR) are Queensland's contaminated land registers under the Environmental Protection Act 1994. The EMR lists land where a notifiable activity has occurred or contamination is suspected; the CLR lists land that is contaminated and requires remediation or management.
Do I need a contaminated land assessment to get planning approval?
Often, yes. In Queensland, development on EMR/CLR-listed land can trigger assessment obligations under the Environmental Protection Act 1994 before approval. If your site has a potentially contaminating history, an assessment is usually required to support the application.
How much does it cost to dispose of contaminated soil?
Disposal cost depends on the soil's waste classification plus the state waste levy and landfill gate fees. Queensland's metro-zone levy is $135 per tonne for general waste and contaminated earth from 1 July 2026. Accurate classification and segregating clean from contaminated material are the most effective ways to control total disposal cost.
Do contaminated land reports need to be done by a qualified consultant?
Yes. In Queensland, contaminated land assessment reports must be prepared by a Suitably Qualified Person (SQP). Using a qualified consultant from the outset avoids re-work, auditor rejection and approval delays.
