Subject: [CPEO-MEF] Response to Indoor Air Sampling issue 722 (Feb 28, 2003)
The relationship between chemicals in indoor air, soil gas, and groundwater
is complicated. Generally, the ratio of indoor air to soil gas or indoor air
to groundwater is called an attenuation factor and is the result of many
physical, chemical, and biological processes. EPA and many researchers are
studying this. Some buzz names include Vapor Instrusion or Vapor Migration.
There are some general attenuation factors that can apply but they only
apply if conditions meet specific criteria. For more information, one place
to start are at the following two links.
