U.S EPA Releases New Vapor Intrusion Guidance

By Ryan Elliott

Today, U.S. EPA released two technical guidance documents to support assessment and mitigation activities at sites where vapor intrusion is an actual or potential concern, including sites being evaluated under CERCLA and the corrective action provisions of RCRA. The guides present EPA’s current recommendations for identifying, evaluating and managing vapor intrusion.  EPA notes that the two new vapor intrusion guidance documents supersede and replace EPA’s Draft Vapor Intrusion Guidance (November 2002).
