  1. Using Professional JudgmentVapor Intrusion Mitigation Design Presented by: Thomas Hatton Clean Vapor, LLC President

  2. What We Will Be Discussing • Vapor Intrusion Basics • Delineating the Plume • Mapping Permeability • Efficient Design • Inherent Inefficiencies • Overcoming Inherent Inefficiencies • Monitoring , Management and Reporting

  3. VI Mitigation Basics • Create negative pressure below slab • Designed to function under max load conditions • Achieve mandated vacuum requirements • Routine onsite inspections • Run continually

  4. Delineating the Plume Using the mobile lab…

  5. Delineating the Plume

  6. Delineating the Plume

  7. Permeability Mapping

  8. Permeability Mapping

  9. Selecting an Efficient Blower

  10. The problem with current systems… …Conditions Change

  11. Seasonal Pressure Differentials Inherent Inefficiencies Soil Conditions Seasonal Changes Building Pressures Onsite Inspections

  12. Inherent Inefficiencies

  13. Overcoming Inefficiencies • Apply dynamic controls to dynamic conditions • Perform based on predefined parameters • Sub slab vacuum • Air exchange ratios • Remotely: • Monitor system performance • Make system adjustments • Immediate alert of system faults

  14. Vapor Guardian 400 • Monitor up to 4 blower systems • Mobile fault notifications • Automated reporting • Ideal for: • Individual residences • Multi-family housing • Small buildings

  15. Vapor Guardian 5500 • Dynamically control 10 blower systems • Control of sub slab vacuum • Assign functional priority • Sub Slab Pressure • Static Pressure • Airflow • Monitor up to 55 inputs • Mobile fault notifications • Automated reporting -0.005 -0.004 -0.003

  16. Excess Vacuum, Excessive Cost

  17. Case Study – Industrial Building

  18. Conserving Resources 11 barrels 4 tons

  19. Social Responsibility 24,000 lbs. CO2 139 lbs. SO2

  20. Fiscal Responsibility $6,000

  21. Care, Custody, and Control • Long Term Stewardship • Delineating Responsibility • Project Handoff • Continual Monitoring • Liability Ownership • Inspections • State Reports

  22. Remote Monitoring

  23. Automated Reports Automatically generated quarterly Operations and Maintenance report from remote monitoring and management system.

  24. Conclusions • Apply professional judgment in design • Current systems are inefficient • Dynamic conditions require dynamic controls • Dynamic controls and remote monitoring save: • Resources • Environment • Money • Liability • Peace of mind • Healthier living
