The Vapor Intrusion Toolbox will be used to post documents for OSCs and RPMs to use in response to Vapor Intrusion Sites. Vapor intrusion is the migration of volatile chemicals from the subsurface into overlying buildings.
Please note, some documents may be marked 'private' and require a response.epa.gov account to access. If you do not have an account, you can register for an account via this link. Please contact Jackie Cole or Betsy Nightingale with any questions.
