Description: This course provides an overview of the vapor intrusion exposure pathway including its scientific foundation, regulatory framework, and the technical aspects of investigating and remediating contaminated vapor sites. The class will cover topics such as: screening sites for potential vapor intrusion concerns, conducting field investigations, sampling techniques, data analyses, exposure point calculations, the Johnson and Ettinger predictive model, vapor intrusion risk assessment, vapor intrusion mitigation, and remediation. Participants will work through practical problems and typical site scenarios based on case studies of established vapor intrusion sites. This course provides a comprehensive introduction for those new to the field, and will also provide insights, data analysis techniques, and the latest research for more advanced participants. |
