 A conceptual site model (CSM) is a simple description of the key processes at a site and is used to support characterizations, risk assessments, remediation planning, and implementation. In general, the CSM for VI consists of vapor sources, subsurface vapor migration potential, driving forces from the subsurface into buildings, and mixing of chemicals in indoor air<ref name= "USEPA2012b">U.S. Environmental Protection Agency (USEPA), 2012. Conceptual Model Scenarios for the Vapor Intrusion Pathway. USEPA, Washington, DC. EPA-530-R-10-03. [[Media:USEPA-2012b._Conceptual_Model_Scenarios_for_Vapor_Intrusion_Pathway.pdf|Report.pdf]]</ref>. A simplified VI CSM is as follows (Fig. 1):
