2018 International Workshop on Investigation and Mitigation of Vapor Intrusion

 

Objective

 

Vapor intrusion is the migration of chemical vapors from subsurface contaminant sources through building foundations into buildings. Recognition of soil vapor intrusion to buildings and other enclosed spaces occurred in the 1980s with concerns over radon intrusion. There has been an increasing awareness that anthropogenic chemicals (e.g., chlorinated solvents petroleum hydrocarbons and) in soil, groundwater, soil gas, and sewers can pose a human health risk to building occupants via the vapor intrusion pathway.The International Workshop on Investigation and Mitigation of Vapor Intrusion will be held December 5-6 in Tainan. Mathew Plate and Alana Lee serve as speakers in this workshop. Mr. Plate and Ms. Lee have lead vapor intrusion research projects assessing and developing monitoring techniques that are practical, cost-effective, and improve our understanding of subsurface contaminant vapor intrusion transport from the subsurface into buildings.Taiwan EPA and TASGEP hope you to join us!!
