The New Vapor Intrusion Standard

Published in Scotsman Guide

Learn the ins and outs of ASTM’s 2008 benchmark for toxic-vapor assessment. The migration of toxic vapors into structures and breathing zones has long been a significant concern associated with environmentally impacted real estate. In 2008, the American Society of Testing and Materials (ASTM) published a new standard dealing with vapor intrusion — “ASTM E2600-08 Standard Practice for Assessment of Vapor Intrusion into Structures on Property Involved in a Real Estate Transaction.” 

The standard creates a legal duty of disclosure from sellers to buyers and from landlords to tenants. Property owners therefore must investigate and disclose vapor intrusion if it exists on their real estate. Otherwise, they risk incurring negligent or intentional nondisclosure liability.
