Research is being conducted worldwide on non-PFAS-containing firefighting foams that can perform effectively and meet legal and other requirements in place for firefighting chemicals. As substitute products are approved for use, existing fire extinguishing systems that used PFAS-containing chemicals will need to be replaced or decontaminated.

CDM Smith U.S. is working with Cornelsen, TRS Group, and the U.S. Department of Defense to validate if PerflourAd^®, a technology that removes PFAS, can be used to treat the rinsing water used to clean firefighting foam delivery systems and more generally water contaminated with PFAS.

PerfluorAd^® is a biodegrad­able agent that attracts PFAS and forms a solid precipitate that can then be separated from water. The PFAS solids can then be destroyed or disposed.

In addition to decon­t­a­m­i­nat­ing fire extin­guish­ing systems, PerfluorAd^® could potentially be used for high-load PFAS-cont­a­m­i­nated waters. It may be applicable to remediation sites with PFAS-cont­a­m­i­nated groundwater, or areas where PFAS-containing fire extin­guish­ing foams were applied.
