Early Investment in PFAS Science
crcCARE recognised the environmental threat of PFAS chemicals long before they became a global concern. In 2005, only a few labs could reliably detect PFOS or PFOA, yet crcCARE began building expertise in analytical methods, hydrogeology, soil science, and ecotoxicology. This early focus allowed the organisation to understand the persistence, mobility, and complex exposure pathways of these “forever chemicals” before contamination became widespread.
Foundational Research Insights
crcCARE’s research generated critical knowledge about PFAS behaviour, including:
- Field monitoring using innovative smartphone approaches.
- PFAS movement in iron- and aluminium-rich soils.
- pH-dependent sorption changes affecting mobility.
- Plant uptake and food-chain transfer near contaminated sites.
- Groundwater plume formation under variable flow conditions.
- Ecological impacts on microbes and groundwater fauna.
These early findings shaped Australia’s national PFAS agenda and guided global understanding.
PFAS Monitoring and the Smartphone Platform
crcCARE developed a smartphone-enabled platform for rapid PFAS monitoring, detecting levels around 2 ppb. It allows field-based risk screening, operational monitoring, and emergency response. With regulatory standards moving toward sub-ppb levels, crcCARE is advancing sensor chemistry and data analytics to meet these stricter thresholds. The platform addresses a global market estimated at US$4–6 billion annually for PFAS monitoring and compliance.
Pioneering PFAS Remediation
matCARE: The First Field-Validated PFAS Treatment
In 2009, crcCARE deployed the world’s first operational PFAS treatment system. It revealed how PFAS removal depends on flow rate, chemistry, and pre-treatment, establishing principles that now guide remediation globally.
pfasCARE™: Breaking the Carbon–Fluorine Bond
Unlike traditional “capture-and-contain” methods, pfasCARE™ destroys PFAS molecules completely. The multi-stage electrochemical process cleaves C–F bonds, mineralises intermediates, and prevents accumulation of short-chain PFAS. The technology has been validated through field trials, ensuring treated water meets strict discharge criteria.
Mobile PFAS Treatment Units
To address remote or urgent contamination, crcCARE developed mobile units capable of on-site PFAS treatment. They provide immediate stabilisation, emergency response, and temporary treatment for defence, mining, industrial, and regional communities.
Horizontal Subsurface Reactor
For challenging groundwater plumes, crcCARE’s world-first horizontal reactor treats PFAS in situ using passive hydraulic flow. It achieves high removal efficiency, structural stability, and minimal maintenance.
Soil PFAS Management: matCARE™ and nanomatCARE™
crcCARE developed materials that immobilise PFAS in soils, reducing leaching, plant uptake, and ecological exposure. Seven-year field trials demonstrated:
- 98% reduction in mobility.
- Preservation of soil function and microbial health.
- Compatibility with agriculture and redevelopment.
This evidence-based approach sets a global standard for soil PFAS management.
Ecotoxicology and Exposure Science
crcCARE’s work revealed PFAS impacts on microbes, plants, and groundwater fauna. Key insights include:
- Disruption of nitrogen cycling and microbial community structure.
- Bioaccumulation in vegetables, informing safe food practices.
- Stress and reproductive impairment in stygofauna, protecting aquifer ecosystems.
Capacity Building and Global Deployment
crcCARE trains thousands of professionals through structured programs covering sampling, risk assessment, remediation, and monitoring. AI-enabled tools optimise plume prediction, mobility modelling, and remediation strategies. Internationally, crcCARE advises governments, supports industry, and implements PFAS solutions in Asia, the Gulf, Africa, and the Pacific.
Integrated PFAS Solutions
crcCARE combines:
- Analytical method development.
- Soil, water, and groundwater research.
- Field and lab remediation technologies.
- Ecotoxicology and exposure science.
- AI-driven modelling and decision support.
- National and international training.
- Mobile and permanent remediation deployment.
This end-to-end approach ensures scientific rigour and operational effectiveness, establishing crcCARE as a global authority.
Thought Leadership and Knowledge Sharing
crcCARE initiated the CleanUp Conference series and the first international PFAS symposium, creating platforms for global discussion, policy shaping, and dissemination of PFAS science.
