GREEN CONSTRUCTION Compliance with vapor intrusion guidelines is a moving target. BY LEONARD KURFIRST AND RICHARD SHERMAN CLEARING THE AIR I n the acquisition, construction and renovation of residential, commercial and industrial property, indoor air quality is a growing concern for regulators at both the state and federal levels. While conventional environmental regulation has focused on outdoor air, soil and groundwater quality, there has been increased recognition that poor indoor air quality can adversely impact human health. This has led regulators and environmental consultants to address vapor intrusion issues in various ways, not all of which are consistent. What then do construction professionals generally need to know regarding this developing issue? A Brief Overview “Vapor intrusion” is generically defined as the presence in indoor air of pollutants such as volatile organic compounds (VOCs) that have volatilized from soil or groundwater under or proximate to the indoor space. Clearly, certain types of property, such as those that are part of brownfield revitalization programs, are more at risk than others for vapor intrusion.

The federal Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) provides a defense to potential environmental liability if a purchaser or developer can demonstrate that “all appropriate inquiry” was made into uses of the property under previous ownership. Generally, due diligence can be established by obtaining a Phase 1 environmental site assessment (ESA).
