New PFAS Research Project: Sustainable Cleaning with PerfluorAd™ Treatment Technology

New PFAS Research Project: Sustainable Cleaning with PerfluorAd™ Treatment Technology
9 March 2021
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 several 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 the PerfluorAdTM treatment technology, which can remove PFAS from water, can also be used to clean firefighting foam delivery systems. The technology involves the use of a weak biodegradable, plant-based acid that attracts PFAS and forms a solid precipitate, which can be separated from water. The PFAS solids can then be destroyed or disposed.

Additionally, the PerfluorAdTM system could 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.
