In the final installment from our webinar, "The Best of VI in '25," David Hanley of Hanley Environmental discusses the utilization of Pressure Field Extension (PFE) testing to determine the performance of passive or active vapor intrusion mitigation systems.
David's presentation focuses on PFE specifically for mitigation on new construction buildings. Looked at data spanning more than 15 new buildings where they performed PFE to improve VIMS design in the future.
- Data was collected between 2022 – 2025
- Took a deep dive into the data and highlighted results
- Defines what PFE testing actually is and highlights the fundamentals.
