Course Overview
This course will provide a full spectrum look into current practices of vapor intrusion mitigation system design and installation. The program will begin with a solid foundation of system design and a theoretical framework for functionality. Furthermore, it will delve into practical mitigation strategies along with the shortcomings of adapting antiquated inefficient design to modern mitigation systems in both retrofit and new construction scenarios.

Student Reviews
“I really liked the information on new construction techniques and methodologies.”
– Past Participant
Most useful aspect of the course: “The clarity for some of the mitigation techniques. Providing photos of how unique situations were addressed is very appreciated. Most courses I take talk about the steps somewhat vaguely so it becomes harder to apply in real situations.”
– Past Participant
“Loaded with great information. Teachers were great.”
