Effort to Use Regenerable Anion Exchange Resin as a Bridge to PFAS Destruction at Naval Air Station Joint Base Willow Grove

PORTLAND, Maine – February 1, 2024 – ECT2 is excited to announce its participation in a new prototype project funded by the Department of Defense (DoD)’s Environmental Security Technology Certification Program (ESTCP) to design, build and operate a regenerable anion exchange resin system to treat per- and polyfluoroalkyl substances (PFAS) in groundwater at the former Naval Air Station Joint Base (NAS JRB) Willow Grove. The project is in partnership with the DoD’s ESTCP, the U.S. Air Force, the U.S. Navy and the Defense Innovation Unit (DIU).

ECT2’s novel approach to PFAS treatment achieves very low treatment goals for PFAS in the treated water and minimizes waste generation via an onsite media regeneration process that allows for continuous reuse of the treatment media. A high-concentration, liquid PFAS waste concentrate (“still bottoms”) that is suitable for PFAS destruction applications is the end product of the regeneration process. Following ECT2’s demonstration, multiple PFAS destruction technology vendors will receive the still bottoms (PFAS waste concentrate), along with other wastes, to demonstrate PFAS destruction.

With more than seven years of experience treating PFAS-impacted water, ECT2 was one of three companies selected to perform water source remediation work at NAS JRB Willow Grove. ECT2 designed its prototype project to demonstrate the efficacy and flexibility of regenerable anion exchange resin to treat a range of long-and-short-chain PFAS. Treatment targets include the proposed drinking water maximum contaminant levels (MCLs) set by the US EPA, as well as the proposed US EPA Regional Screening Levels (RSLs) targeting short-chain compounds like PFBA and PFHxA.

“This ESTCP/DIU project helps to realize a key goal for the Department of Defense by implementing effective, full-scale treatment approaches to PFAS that in some cases the DoD has funded from inception through the SERDP and ESTCP research and demonstration programs,” said Dr. Erika Houtz, ECT2’s principal investigator on the project. “ESTCP/DIU’s demonstration approach will offer an important technical vetting and economic comparison of multiple technology pairings. ECT2 is proud to help advance the DoD’s remediation goals through this program.”

ECT2 will begin prototype demonstration in Willow Grove, Pennsylvania in mid-2024. The ESTCP/DIU project is expected to conclude in 2025.
