Vapor intrusion definition

Vapor intrusion means the migration of volatile chemicals from contaminated environmental media into a building, subsurface conduit or structure.
Vapor intrusion means the migration of volatile or semi-volatile chemicals from contaminated environmental media or product into a building, subsurface conduit or structure.
Vapor intrusion means the migration of volatile chemicals from the subsurface into overlying buildings through subsurface soils or preferential pathways (such as underground utilities).

Examples of Vapor intrusion in a sentence

  • Vapor intrusion can pose a potential health threat to the occupants of the building, especially to sensitive populations such as the elderly and children.

  • Vapor intrusion occurs when chemicals volatilize and migrate from impacted soil and/or groundwater up into a building’s interior space.

  • Vapor intrusion is defined as the migration of volatile contaminants from the subsurface into overlying buildings.

  • Characterization and Risk Assessment Techniques Vapor intrusion is typically first evaluated with charac­ terization measurement and risk assessment techniques.

  • Secondary indica­ tors of performance may include engineering parameters such as pressure differentials and AER.Several factors influence the premitigation performance baseline to which system performance is compared, and thus should be held constant to the extent possible in system performance measurements:• Vapor intrusion is expected to be seasonally and temporally variable (influenced by weather) at most sites.
