Case Study | Regulatory Closure Achieved Using PetroFix on Legacy UST Site
Case Study Highlights:
- PetroFix reduced contaminant levels below cleanup goals, enabling site closure.
- The former UST site faced persistent benzene and naphthalene contamination despite a decade of prior treatments.
- A biologically guided remedial strategy was implemented with PetroFix, marking its first use in North Carolina.
Technical Review Summary | PFAS Monitored-Retention: A Framework for Managing PFAS-Contaminted Groundwater Sites
Key Takeaways:
- PFAS Enhanced Retention (PER): Adds tools like PlumeStop® and SourceStop® to boost aquifer sorption where PMR alone isn’t protective.
- PFAS Monitored Retention (PMR): A DoD-backed framework using natural retention (sorption, diffusion, etc.) to slow PFAS plume migration.
- Hybrid Approach: PER + PMR offers a scalable, cost-effective, and regulatory-aligned strategy to manage PFAS plumes.
Project Snapshot | SourceStop Barrier Effectively Mitigates PFAS at Former Landfill Site
Project Snapshot Highlights:
- Former landfill released PFAS to groundwater, exceeding regulatory limits.
- SourceStop barrier chosen to halt plume migration and avoid excavation or waste disposal.
- REGENESIS applied SourceStop in situ for long-term PFAS
Episode Highlights:
- Explanation of PFAS Monitored Retention (PMR) as a cost-effective, science-backed strategy.
- How PMR slows PFAS plume migration and reduces risk without full-scale treatment.
- Ideal site types as a practical middle-ground approach.
