Vapor Intrusion Mitigation

Remediation of vapor intrusion impacts may be required if the vapor intrusion pathway is determined to be complete at a site and indoor air concentrations of volatile chemicals exceed levels of concern. This page includes links to resources for addressing the mitigation of vapor intrusion sites.

Mitigation of VOCs in Indoor Air

EPA Air/Superfund National Technical Guidance Study Series. Options for developing and evaluating mitigation strategies for indoor air impacts at CERCLA sites. September 1993. EPA-451/R-93-012. (PDF) (174 pp, 7.3 MB, About PDF)
This document evaluates approaches that may be used to mitigate Superfund site impacts on the indoor air quality of nearby structures.

Indoor Air Vapor Intrusion Mitigation Approaches
This is an Engineering Issue that summarizes available information on site remediation technologies and related issues regarding vapor intrusion.

Radon Mitigation

Techniques for mitigating radon in indoor air may also be used to mitigate the intrusion of VOCs into buildings.

EPA's Radon Web page contains a wealth of information on radon including links to resources and publications on mitigating radon in homes
