TRI-SERVICE ENVIRONMENTAL RISK ASSESSMENT WORKGROUP: VAPOR INTRUSION FACT SHEETS
A series of fact sheets has been prepared by DoD's Tri-Service Environmental Risk Assessment Workgroup to update and supplement the DoD Vapor Intrusion Handbook (2009). Begun in 2017, this fact sheet series covers sampling and assessment techniques that allow for an improved understanding of VI given temporal variability and the potential for the presence of background sources of VOCs. The 2019 fact sheet update presents a matrix for selecting VI investigation technologies and ranks the various technologies to facilitate selection of an effective approach. Selection is based on the specific investigation objectives, including characterization of subsurface sources, evaluation of vadose zone vapor migration pathways, and investigation of a building's sub-slab region and interior. The following fact sheet updates have been posted:
No 1: Rev 1: Passive Sampling for Vapor Intrusion Assessment (7 pp, Feb 2017)
No 2: Real-Time Monitoring for Vapor Intrusion Assessment (9 pp, Feb 2017)
No 3: High Volume Soil Gas Sampling for Vapor Intrusion Assessment (14 pp, Feb 2017)
No 4: Use of Building Pressure Cycling in Vapor Intrusion Assessment (9 pp, Aug 2017)
No 5: Use of Tracers, Surrogates, and Indicator Parameters in Vapor Intrusion Assessment (13 pp, Sep 2017)
No 6: Determining the Influence of Background Sources on Indoor Air Concentrations in Vapor Intrusion Assessment (10 pp, Sep 2017)
No 7: Matrix for Selecting Vapor Intrusion Investigation Technologies (15 pp, Jul 2019)
