With the prevalence of Firefighting foam having been identified as an issue for site contamination, SERS have recently begun undertaking the identification and removal of contaminated soils from a number of sites in the Perth metropolitan area for one of our main clients.
These firefighting foams were used to fight fires and for firefighting training from the 1970s to the mid-2000s and contained manufactured chemicals improve their ability to smother fires.
These manufactured chemicals were perfluoroalkyl and polyfluoroalkyl substances—such as perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA) and perfluorohexane sulfonate (PFHxS).
The foams have been used at various sites in Western Australia including civil airports, military air bases, fire training facilities, large fuel storage terminals and refineries and ports.
SERS have been undertaking the removal supervision, soil sample collection and analysis for the presence of PFAS, PFOS and PFHxS, along with waste classification for disposal recommendations.
