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.

"This course was very organized and interesting...gave real life case studies that helped me understand the topics that were taught throughout the course." K. Erney, February 2013

"Thorough.  The instructor included references to local (state) guidance and its divergence from other VI guidance." C. Grover, February 2013

"I really liked how the instructor used state specific guidance and compared it to other states' + EPA guidance...the case studies were great - really illustrated the content of the course." R. Ridenour, February 2013

"The instructor is knowledgeable and very willing to engage students." D. Hammer, February 2013

"His extensive real world experience gave confidence in his knowledge." R. Timmins, August 2013

"Very good course overall very helpful as an introduction to VI.  Instructor very knowledgable and explained content in a very clear way." L. Galu, August 2013

 

*Reduced tuition is available to employees of Native American tribes, government agencies, nonprofits, students and NAEP members.

About the Instructor

Elie H. Haddad

Elie H. Haddad

Mr. Haddad is a vice president for Haley and Aldrich where he is involved in vapor intrusion investigations, remediation and modeling, risk assessments, planning and strategy, development and implementation of RI/FS programs, engineering designs, hydrogeological activities, computer modeling, and operation and maintenance programs. He led an unprecedented, and perhaps largest, indoor air investigation at a Superfund site. His work established a benchmark for other EPA sites. Mr. Haddad has used his skills to allocate remedial costs among potentially responsible parties at several sites, and to allow redevelopment of several contaminated properties into commercial uses. He supervised the development of remedial design for several Superfund sites, developed and used soil, groundwater, and air dispersion model, and is an expert in hydrogeological applications. Mr. Haddad is also a faculty member of the University of California at Berkeley Extension Program where he has taught the course "Fate and Transport of Contaminants in the Environment". In addition, Mr. Haddad serves on the seminar committee of the Groundwater Resources Association where he has chaired several seminars on various topics including vapor intrusion.
