New PFAS research project: Sustainable cleaning with PerfluorAd®

9 March 2021
USA
Per- and polyfluoroalkyl substances (PFAS) are a diverse group of more than 4,000 individual chemicals that have been widely used - including numerous consumer products and often in fire-fighting foams. Evidence suggests a number of PFAS compounds can have deleterious health effects. Because of their wide ranging applications and use, PFAS is being found in soil and groundwater around the world.

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.

Evaluating novel technologies for PFAS removal

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® Against 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.
