Vapor Intrusion

Vapor Intrusion refers to the migration of vapors from subsurface contaminant sources to buildings such as a homes or workplaces. API conducts research towards improving the screening process for vapor intrusion at sites where petroleum releases have occurred.


Vapor Intrusion Training News
The Interstate Technology Regulatory Council (ITRC) ran the 1st of several planned 2-day vapor intrusion training classes on October 7-8, 2008 in Portland, OR. ITRC's training supports their well-received 2007 vapor intrusion guidance by providing in-depth information on developing site conceptual models, site investigation, data evaluation and mitigation. Class exercises allow attendees to apply their experience and newly-gained knowledge to real-world vapor intrusion scenarios.

On March 16 2008, API conducted a 1/2-day workshop: "Assessing Vapor Intrusion at Petroleum Release Sites" at the 20th Annual National Tanks Conference and Expo in Atlanta, GA. The goal of this workshop was to provide the most up-to-date, cost effective strategies for verifying bioattenuation and determining the significance of the vapor intrusion pathway. The workshop emphasized principles of vapor movement and attenuation, site conceptual model development, and collection of high-quality data. A similar workshop will be presented at the 19th Annual AEHS Meeting & West Coast Conference on Soils, Sediments, and Water; March 9-12, Marriott Mission Valley, San Diego, California.
