Remediation & Treatment

Clients throughout Australia and across industries face an array of known and emerging contaminants in soil, sediment, and water. They need field-leading consultants who listen to their needs, help them discover the sources and types of contamination, choose and implement strategies, and navigate regulations to reach their desired outcomes.

Comprehensive Solutions for Soil, Ground Gas, Groundwater, Sediment & Surface Water

Geosyntec practitioners help clients create tailored remediation plans, consult on regulatory strategies, and develop and implement cleanup approaches. We listen to and work with our clients to deliver contamination solutions that achieve their project outcomes. Our people are adept at addressing contaminants a wide variety of contaminants, including trichloroethylene (TCE), per- and polyfluoroalkyl substances (PFAS), asbestos, chromium, and fuels.

Our technical expertise includes a wide range of potential remediation approaches, including in situ and ex situ contaminant destruction, effective stabilisation and containment, and advanced thermal and biological processes.

With decades of experience in remediation and auditing, we deliver informed and precise guidance, rooted in best practices, to build optimal outcomes from offices throughout Australia.

Flexible, Targeted Environmental Remediation that Unlocks Value

Whether clients need tight-access metro works or remote systems in challenging environments, they seek out Geosyntec because we can deliver targeted, flexible, and innovative solutions. They choose us because our practitioners rank among the world’s top professionals in assessing and remediating a wide range of impacted sites while consistently advancing the state of the practice.

Innovative Treatment Options to Build Comprehensive Solutions to the Toughest Environmental Challenges

In addition to the breadth and depth of our experience across Australia, clients know that we are the developers of the technologies other consultants implement.

Our innovators collaborate to design and construct effective systems for the toughest challenges by employing innovative solutions and practical experience:

• In situ and ex situ treatment systems for soil, water, and ground gas, including in situ chemical oxidation (ISCO) and bioaugmentation
• In-house bench-scale trials to support remediation systems
• An in-house laboratory, SiREM, to support remediation and monitoring, with tools including treatability testing, molecular genetic testing, and passive sampling
• National experts connected to field-leading practitioners worldwide
• Expertise with emerging contaminants
• Experience on all sizes of systems, from containerized plants to permanent treatment systems
• Accredited auditors in all major Australian regulatory schemes

Remediation

Pragmatic, cost effective & technically defensible remediation solutions. From immediate response to complex, long-term treatment systems.

Geosyntec provides end-to-end remediation services, combining our deep contaminated land expertise with the capability to design, construct, commission, optimise, and operate remediation systems. We deliver solutions across Australia—from compact treatment systems installed in constrained metropolitan sites, through to large-scale permanent treatment plants operating in remote and challenging environments.

Our experience spans short-term emergency response measures through to treatment systems that have been operating continuously for more than a decade. We have delivered remediation solutions for major mining, construction, Defence, industrial, and infrastructure clients and have a proven record of deploying solutions to support our clients in short turnaround times.

Remediation Solutions Tailored to the Site

No two remediation projects are the same. Geosyntec designs treatment solutions around the cleanup goals, contaminant profile, hydrogeology, site constraints, regulatory requirements, and ultimate client objectives—not a predetermined technology.

Our teams have applied a broad range of remediation technologies to address major contaminant groups, including petroleum hydrocarbons, chlorinated solvents, PFAS, metals, and other emerging contaminants of concern. This breadth of experience allows us to evaluate technology options objectively and develop solutions appropriate to the specific technical and commercial drivers of each project.

From Bench-Scale Testing to Full-Scale Operation

Geosyntec provides full turnkey in-house design and commissioning capability, enabling remediation concepts to be developed, tested, and translated into practical field-scale systems.

Our Australian facilities support bench-scale trials, treatability testing, and project-specific system development, complemented by access to Geosyntec’s specialist SiREM laboratories and international remediation experts.

This experience gives us the capability to mobilise and deliver treatment solutions anywhere in Australia, including locations where access, logistics, environmental sensitivity, or ongoing operations introduce significant additional complexity.

More Than a Remediation Contractor

One of Geosyntec’s key differentiators is that remediation delivery sits within a broader contaminated land, auditing, and environmental practice.

Our teams understand the complete project life cycle—from site investigation and conceptual site models through risk assessment, remediation design and implementation, validation, regulatory engagement, and, ultimately, site closure.

This broader perspective means we don’t simply operate a treatment system. We understand why remediation is being undertaken, what outcome needs to be achieved and how the technical, regulatory, and commercial pieces fit together.
