Confusion Surrounding Vapor Intrusion Risk

Partner answers some FAQs about vapor intrusion risk, regulation, and its impact on the multifamily industry.

Although the concept of Vapor Intrusion or Encroachment has been around for a while, it has become more prominent in recent years due to the industry’s improved understanding of the potential risks it poses to human health, and the subsequent regulatory focus it has received. ASTM E1527-13 (released in 2013) first placed a much greater emphasis on assessing vapor risks during the Phase I ESA. And just recently, ASTM recently released updates to the E2600-15: Standard Guide for Vapor Encroachment Screening on Property Involved in Real Estate Transactions to improve guidance on how vapor risk should be assessed.
