Introduction to Arcadis Foam Transition Cleaning Procedures, Cleaning Agents and Case Studies for Removal in ARFF Apparatus/Fire Suppression Systems

Managing PFAS-containing AFFF remains a top priority for emergency responders and firehouses worldwide. Replacement of PFAS-containing AFFF without proper residuals management and infrastructure cleaning often results in rebound of PFAS into the newly installed AFFF. Arcadis has developed and demonstrated a proprietary cleaning agent and procedure that is effective at reducing PFAS mass that is coating surfaces. The cleaning agent, Arcadis V171, has been used successfully on a wide range of materials and systems, including foam distribution and suppression systems and emergency response vehicles. This presentation discusses the past successes of Arcadis V171 applications and the importance of the developed procedure coupled with collaboration with site personnel.

John Anderson, P.E. – Senior Water Engineer

Mr. Anderson has worked as an environmental and water engineer for more than 10 years. Currently, Mr. Anderson is working not only on PFAS treatment system designs but also promoting and optimizing the procedures and formulations of Arcadis’ proprietary cleaning agent for PFAS infrastructure cleaning. Mr. Anderson has operated as lead engineer on PFAS cleaning projects for foam distribution systems and for ARFF and emergency response apparatuses.

Dr. Johnsie Lang

Dr. Lang has extensive expertise in assessment and monitoring of PFASs in solid, gas phase, and aqueous samples.  She has determined the target and non-target PFAS content on products including fast food packaging.  She has proficiency in examining the fate and transport of recalcitrant pollutants in the environment, including HAB toxins and PFASs.  Recently, Dr. Lang has focused her efforts on developing a method for removing residual PFASs from fire suppression systems during foam transition.
