Vapor Intrusion & Vapor Encroachment

Vapor Intrusion has emerged as a significant environmental issue in recent years. On June 14, 2010, ASTM published E 2600-10, Standard Guide for Vapor Encroachment Screening on Property Involved in Real Estate Transactions. This standard replaces E 2600-08, published in March of 2008. It is anticipated that the screening under ASTM E 2600-10 will eventually become a routine part of an AAI-compliant Phase I environmental site assessment. A number of institutions such as HUD already require their consultants to consider vapor encroachment onto the property in their Phase I investigations.

On January 31, 2011, the U.S. Environmental Protection Agency opened a public comment period on a proposal to add a new screening mechanism to the Hazard Ranking System that would enable sites with vapor intrusion contamination to be evaluated for placement on the NPL or Superfund list.
