Environmental Remediation & Management
Contaminated land remediation: preparing sites for safe development
Making a site safe for its intended use – and for human health – requires expert environmental remediation or management. The right approach depends on the nature and extent of contamination, from targeted removal through to ongoing management according to a site-specific plan.
Atma brings considerable expertise across all aspects of environmental remediation and management, guiding projects from initial planning through to on-ground delivery. Backed by experience across hundreds of sites throughout Victoria, we understand how to develop cost-effective, technically sound, site-specific solutions that meet regulatory requirements, provide project certainty, and prepare sites for safe development or new use.
What we do
We provide a complete approach to remediation. From project planning and tendering, to site works supervision and monitoring, right through to final validation and sign-off.
Remediation Planning
Remediation planning defines how contamination will be safely removed, treated or contained. The approach depends on the nature and extent of contamination, as well as project requirements.
Remediation Action Plans (RAP) provide a detailed strategy for managing contamination, including remediation methods, risk management and validation. RAPs are typically used for larger or more complex projects and are often required for planning approval.
Remediation Delivery
Effective site remediation requires selecting the right approach for each site. A wide range of techniques are available for the treatment, containment or removal of contaminated soil and groundwater, with the most appropriate method determined by site conditions, contamination profile and project requirements.
Atma works with a network of experienced, specialist contractors to deliver remediation works safely and efficiently. We manage the process from contractor selection through to on-site implementation, ensuring works are carried out in accordance with the remediation plan and regulatory requirements.
Our team provides hands-on, at-site project oversight to resolve issues, monitor progress and maintain quality control. This ensures your remediation program is delivered efficiently, the risks are managed, and it remains on track.
Risk Assessment & Cost Evaluation
Understanding risk is critical to making informed decisions about contaminated land. Atma provides site-specific risk assessments to evaluate potential impacts on human health, the environment and project outcomes.
These assessments support due diligence prior to site acquisition, help define the extent of remediation required, and provide clarity on potential costs and liabilities. By quantifying risk and identifying appropriate management strategies, we help clients make confident, commercially sound decisions and avoid unnecessary remediation or over-engineering.
Management Plans
Management plans are developed as a way of controlling identifiable hazards that may be associated with the condition of a site, or with a particular activity or business.
Site Contamination Management Plans
Not all contaminated sites require the removal of contamination. Depending on the nature of the contamination and the intended land use, site contamination risks associated with contaminated soil, groundwater or vapour can often be effectively managed through a site-specific management plan.
Site contamination management plans set out the procedures, responsibilities and controls required to manage contamination safely, minimise risk to human health and the environment, and meet regulatory obligations.
Environmental Management Plans (EMP)
Businesses in Victoria have a General Environmental Duty under the Act to identify the potential environmental impacts of their operations and to put appropriate controls in place. Atma Environmental consults with businesses to understand their processes, research best practices and develop workable, tailored EMPs to address aspects such as noise and other emissions, to the satisfaction of local government authorities and other stakeholders.
Asbestos Management Plans (AMP)
Atma develops plans clearly setting out the procedures for identifying, handling and managing asbestos which has been found or, which could be found on worksites in a compliant manner.
Groundwater Quality Management Plans (GQMP)
Following the completion of a detailed site investigation and/or environmental audit it may be concluded that polluted groundwater requires ongoing monitoring to ensure it is stable and that the contamination risks remain acceptable.
GQMPs detail the required groundwater sampling and analysis requirements, trigger levels, testing frequency and reporting requirements.
Our Process
Successful remediation demands a clear strategy, confident decision-making and disciplined delivery. We take ownership of the process from planning through to on-ground implementation, ensuring onsite issues are efficiently resolved and outcomes are delivered with certainty.
While each site is unique, our approach follows a proven, structured process.
Review & Strategy
We review existing site information, contamination data and project requirements to define the most appropriate remediation or management approach. This includes identifying risks, constraints and practical pathways forward.
Planning
Solid planning to reduce or eliminate unforeseen circumstances is the investment we bring to ensure a smooth delivery in line with expectations.
Contractor Engagement
We engage and coordinate experienced specialist contractors, managing procurement and ensuring the right expertise is engaged for the project.
Implementation & Oversight
We oversee on-site remediation works, coordinating contractors, monitoring progress and maintaining quality control to ensure works are delivered safely, efficiently and in accordance with approved plans.
Validation & Ongoing Management
We verify that remediation objectives have been achieved through validation and reporting. Where required, we establish ongoing management and monitoring to ensure continued compliance and long-term site safety.

FAQs
How can remediation costs be managed and unexpected issues minimised?
Remediation projects can involve significant costs, which is why careful planning and site characterisation are critical. Atma takes a strategic approach to remediation by identifying data gaps early, assessing alternative remediation options, obtaining specialist input where required, and preparing detailed remediation plans before works commence.
The most appropriate remediation method will depend on the specific site conditions and contaminants present. Solutions can range from targeted excavation and disposal of impacted soils through to more complex groundwater treatment systems. By thoroughly understanding site conditions, evaluating available options and managing remediation works closely, we help clients reduce uncertainty, control costs and achieve regulatory compliance.
Our experienced team has delivered remediation projects across a wide range of contaminated sites, helping clients achieve safe, compliant and cost-effective outcomes while supporting development approvals and project timelines.
What are the risks of not identifying contamination early?
Failing to identify contamination risks early can lead to unexpected remediation costs, project delays, planning complications and environmental liabilities. Because the extent of contamination is often unknown until investigations are undertaken, delays in assessment can result in significant uncertainty around development costs and timelines.
Early investigation provides a clearer understanding of site conditions, allowing developers to assess potential risks, evaluate management options and make informed decisions before committing to major project expenditure. It also enables contamination issues to be incorporated into project planning, reducing the likelihood of costly surprises later in the development process.
Atma helps clients identify contamination risks early, providing practical advice and cost-effective strategies that improve project certainty and support successful development outcomes.
What is the biggest mistake developers make when managing contaminated land?
One of the most costly mistakes developers can make is commencing demolition, excavation or earthworks before fully understanding the nature and extent of contamination on a site. Disturbing contaminated soil without adequate investigation can spread contamination into previously unaffected areas, increasing remediation costs, disposal requirements and regulatory obligations.
In many cases, a relatively simple investigation undertaken early in the project can identify contamination risks, guide site management activities and help avoid unnecessary remediation expenses. Understanding site conditions before works commence also allows developers to evaluate remediation options and develop a more efficient and cost-effective project strategy.
Atma works closely with developers to identify contamination risks early, assess management options and develop practical remediation approaches that minimise risk, control costs and support project timelines.
How is groundwater contamination remediated?
Groundwater remediation is a specialised process used to manage or reduce contamination within an underground aquifer. The most appropriate remediation approach will depend on the type and extent of contamination, the characteristics of the aquifer and the objectives of the project or environmental audit.
Remediation strategies can range from monitored natural attenuation and groundwater management plans through to active treatment systems designed to reduce contaminant concentrations over time. Selecting the right approach is critical, as groundwater remediation can have a significant impact on project costs, timelines and development outcomes.
Atma works with specialist engineers, hydrogeologists and environmental auditors to assess remediation options, develop practical remediation strategies and oversee implementation. We also provide ongoing groundwater monitoring, performance reporting and regulatory documentation, including Groundwater Quality Management Plans (GQMPs) and Clean Up to the Extent Practicable (CUTEP) assessments where required.
By combining technical expertise with practical project management, we help clients achieve compliant, cost-effective groundwater remediation outcomes while supporting environmental audit and development objectives.
