AECOM is providing clients with long-term PFAS solutions having worked on over 200 PFAS projects globally and managed two of the largest precedent setting PFAS investigations in Australia.


What are PFAS?
Per- and Poly-Fluorinated Substances (PFAS) are chemicals that are resistant to heat, water and oil. They don’t easily break down in the environment due to the way they were manufactured and have the ability to travel thousands of kilometres through the environment.

Globally, PFAS were historically used within firefighting foams, like Aqueous Film Forming Foams (AFFF) on a range of facilities including airports, firefighting stations and industrial areas.

The use of PFAS was common in the following industries:

  • Aviation
  • Defence
  • Oil & Gas
  • Fire Services
  • Property
  • Manufacturing

Why are PFAS a problem?

The worldwide historic use of PFAS has resulted in public and regulatory concerns. Their persistence in humans and animals has caused worldwide concern since PFAS was identified as an ’emerging contaminant’ in the 2000s. Limited understanding of how PFAS impacts human health and the environment had made it the subject of ongoing research and media attention across the world.

How can AECOM help?
AECOM has been helping clients tackle PFAS contamination since 2001. Our global PFAS team assist clients in the identification, management and remediation of PFAS.
