Passive samplers offer some potential benefits compared to conventional sampling methods and may reduce cost and the implications of temporal variability, which would reduce liabilities for the Department of Defense DoD.The objectives of this work were to provide data to demonstrate and validate passive diffusive samplers for assessing soil vapor, indoor air, and outdoor air concentrations of volatile organic compounds VOCs at sites with potential human health risks. These risks were attributable to subsurface vapor intrusion to indoor air by comparing their accuracy and precision to conventional methods identifying capabilities and limitations of various sampler types and providing scientific data to support regulatory review and acceptance where appropriate.
