PFAS Lessons Learned; Treating a Large-Scale AFFF Site Using In-Situ Colloidal Activated Carbon

Language: English
Presenters: Rebecca Mora (AECOM) and Ryan Moore (REGENESIS)

We are pleased to host Rebecca Mora, AECOM Associate Vice President and Senior Technical Leader, who present the lessons learned on a large-scale Aqueous Film Forming Foam (AFFF) release site, when treated in situ using colloidal activated carbon (CAC). This complicated, high-concentration PFAS site was remediated using one of the longest CAC permeable reactive barriers installed, measuring over 500m long. Rebecca is joined by Ryan Moore, PFAS Remediation Program Director at REGENESIS.

Highlights of this free webinar:

• Approach, lessons learned, and performance results after 2 years of post-injection monitoring from an in situ application of a 500m 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

Rebecca Mora
Associate Vice President and Senior Technical Leader, AECOM
Ms. Mora is an Associate Vice President and Senior Technical Leader with AECOM with over 25 years of environmental investigation and remediation experience. She specializes in design and implementation of innovative technologies, particularly for groundwater sites contaminated with current or former emerging contaminants (PFAS, 1,4-dioxane, perchlorate, hexavalent chromium). Most of her career has focused on in situ remediation; with a keen interest in developing cost-effective solutions for industrial and federal clients’ environmental challenges. Ms. Mora received her B.S. in Environmental Engineering from the University of Notre Dame.
