Savannah River ZVI PRB: From Design to Performance
đ
Wednesday, July 29, 2026
â° 12:00â2:00 PM ET
đť Free to attend
đ 2 PDH Certificates for EnviroClass Members Only
đď¸ Hosted by Mike Mazzarese | Senior Remediation Engineer | AST Environmental
About the Webinar
Choosing a remedial technology is one thing, making it work in the field is another. For complex groundwater sites, success comes down to how well the design translates into real-world performance.
In this webinar, we will take you inside a Zero-Valent Iron (ZVI) Permeable Reactive Barrier (PRB) project at the Savannah River Site, showing how a thoughtful, data-driven approach carried the design from concept to implementation and long-term effectiveness.
Deborah Shaffer (Schnell) and Adam Willey will break down each phase of the project, from pre-design investigation through trenchless installation and performance monitoring, with a focus on what made the approach successful. Along the way, they will share practical lessons learned, design decisions that mattered most, and insights you can apply directly to your own sites.
What Youâll Learn
â
 How to move a passive remedy from concept through full-scale implementation
â
 Practical approaches for trenchless PRB installation
â
 The role of pre-design investigations in defining the treatment area and optimizing performance
â
 Key steps in the PRB design process
â
Evaluating PRB performance and achieving regulatory acceptance
