4 Vapor Intrusion Best Management Practices  Vapor Mitigation BMP  Public Communication BMP, factsheets Vapor Intrusion Guidance

5 BMP- Active Mitigation System Installation  Pre-mitigation diagnostic testing to inform system installation  Post-mitigation diagnostic testing to verify pressure field  Post mitigation indoor air and sub-slab sampling.  Make up air to combustion appliances  Contractor certification National Radon Proficiency Program (NRPP) National Radon Safety Board (NRSB)

6 Indoor Air Sampling  Mitigation decisions based on on sub- slab sampling data Indoor Air  Post-mitigation indoor air sampling  Is the mitigation system operating effectively, preventing possibility of vapor intrusion?  Pre-mitigation indoor air sampling  Is a mitigation system needed?

7 Determining Need for Expedited Action  Typical expedited actions  Indoor air sampling  Mitigation system installation  Information for determining expedited action  Sampling results, primarily sub-slab  Basement conditions  Sensitive population present

8 Skilled and Coordinated Communication Jan 2015 Jan 2016 A Primary Concern Is for Health Feelings of anxiety, fear, confusion, helplessness, victimization, anger, outrage Questions such as Will I be affected? What should be done to protect me? How can I know I am safe?
