Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management
10/10/2018 - 10/11/2018
Des Moines, WA

Petroleum vapor intrusion is the process by which volatile petroleum hydrocarbons released as vapors from light nonaqueous phase liquids (LNAPL), petroleum-contaminated soils, or petroleum-contaminated groundwater migrate through the vadose zone and into overlying buildings. Fortunately, this migration is often limited by microorganisms that are normally present in soil. The organisms consume these chemicals, reducing them to nontoxic end products through the process of biodegradation. The ITRC Technical and Regulatory Guidance Web-Based Document, Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management (PVI-1, 2014) and associated training provide a comprehensive methodology for screening, investigating, and managing potential PVI sites and is intended to promote the efficient use of resources and increase confidence in decision making when evaluating the potential for vapor intrusion at petroleum-contaminated sites. By using the ITRC guidance document, the vapor intrusion pathway can be eliminated from further investigation at many sites where soil or groundwater is contaminated with petroleum hydrocarbons or where LNAPL is present.

This event combines the 2-day classroom training on Petroleum Vapor Intrusion from the Interstate Technology and Regulatory Council (ITRC) with an additional bonus day providing a vapor intrusion update from the Michigan Department of Environmental Quality. This 2-day ITRC classroom training led by internationally recognized experts should enable you to:

  • Develop on-the-job skills to screen-out petroleum sites based on the scientifically-supported ITRC strategy and checklist
  • Focus the limited resources investigating those PVI sites that truly represent an unacceptable risk
  • Communicate ITRC PVI strategy and justify science-based decisions to management, clients, and the public
  • Understand the essential principles of biodegradation and the fundamentals of vapor movement through the vadose zone
  • Appreciate the important role of modeling in the investigation of petroleum sites
  • Recognize the extensive options for investigating and mitigating PVI sites

Interactive learning with classroom exercises and Q&A sessions will reinforce these course learning objectives. You will also have the opportunity to network with other environmental professionals.
