PFAS lessons learned treating a large-scale AFFF site using in-situ colloidal activated carbon

Webinar Highlights

We were pleased to host Rebecca Mora, AECOM Associate Vice President and Senior Technical Leader who presented PFAS lessons learned while effectively treating a large-scale, AFFF release in situ using colloidal activated carbon (CAC). The complicated, high-concentration site represents one of the longest CAC permeable reactive barriers installed to address PFAS impacts, measuring over 1,600 feet long. She was joined by Ryan Moore, PFAS Remediation Program Director at REGENESIS.

  • Approach, lessons learned, and performance results after 2 years of post-injection monitoring from an in situ application of a 1,635-foot-long colloidal activated carbon barrier to mitigate PFAS migration
  • Rapid implementation of remedial solution due to perceived regulatory and public pressure
  • Treatment addressing high concentrations of PFAS (up to 550 ppb)
  • Remedial objective to reduce PFAS concentrations in groundwater migrating towards nearby off-site drainage ditches
