We're a specialist waste remediation contractor providing proven solutions in the management of PFAS contaminated soil and water.
Per- and Polyfluoroalkyl Substances (PFAS) are a group of manufactured chemicals used since the 1950s in various products for their heat, stain, grease, and water resistance.
Among over 6,000 identified PFAS, two common ones are Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA). A significant use of PFAS has been in Aqueous Film Forming Foam (AFFF), utilized in firefighting, particularly since the 1970s in Australia.
The Environmental Impact of PFAS
PFAS contamination, primarily from AFFF, has led to significant environmental concerns, especially in areas around Defence bases and Airports in Australia.
These chemicals, due to their non-biodegradable nature, have seeped into soil, surface, and groundwater, and even spread to adjoining lands. Apart from firefighting foams, PFAS are present in various household and industrial products, contributing to environmental contamination.
Their persistence means they can accumulate in wildlife and humans, posing health risks.
We recommend a four-stage process to address contamination at your site
Fully equipped for PFAS removal
Our team is fully equipped to work throughout all domestic and international industries experiencing contamination and can assist in the treatment, remediation, and removal of PFAS:
- Groundwater -long-term remediation and construction sites
- Landfill leachate
- Impacted solids – treatment media, sludges, bio-solids, soils)
- Firefighting system testing solutions
PFAS decontamination and treatment
PFAS compounds, especially AFFF™ used in firefighting, require prompt decontamination to prevent environmental contamination. Southern Cross Environmental Services employs advanced PFAS waste treatment methods.
Thermal Desorption: This process uses heat to evaporate moisture and contaminants from solids. Contaminants are transformed into carbon dioxide and water or condensed for collection. The process operates above the organic compounds’ boiling point, typically up to 550°C, ensuring solids like soil maintain their physical properties for reuse. Treated waste is thoroughly tested to confirm complete decontamination before reuse, recycling, or disposal.
Southern Cross Environmental Services works with regulated facilities nationally that are approved to receive and treat PFAS and provide all necessary documentation including reports and waste tracking to client.
