VI - Monitoring & Mitigation

2.0 PDHs 

Vapor intrusion is the migration of vapor-forming chemicals from any subsurface source into a office, home, or industrial building. It all started in the 1980s with concerns over radon intrusion. During the 90s, environmental professionals began to understand that hydrocarbons and chlorinated solvents in soil, groundwater, and sewers and drainlines could also pose threats to indoor air quality via the vapor intrusion pathway. This EnviroClass will help you understand several of the monitoring and mitigation technologies in the industry.
Harry will begin this class by laying out the use of advanced sorbent samplers and how you can collect time-integrated samples as part of an effective site characterization or vapor intrusion investigation strategy. Page will finish this class by laying out ways that you can protect the first side of your building – the under-slab side.
