Buildings with Vapor Intrusion Problems May Pose a Significant Risk to Building Occupants


Source: Cochrane & Associates, LLC

The environmental professionals at Clark Seif Clark (CSC) provide testing solutions for commercial and residential properties to identify vapor intrusion problems and to protect occupants from any toxic vapors.


Vapor intrusion in any structure creates an environment that could damage structural materials and/or put the building’s occupants’ health at risk.  Reactions to exposure can range from minor irritations, such as headaches or nausea, to more significant problems including chronic disease.  In extreme cases it could even lead to cancer from prolonged exposure. 


Vapor intrusion is defined by building consultants as a gaseous substance migrating into a structure.  Gases such as radon, volatile organic compounds (VOCs), water vapor, or other gases seeps through cracks in the concrete foundations or sewer lines and enter the building. 


According to the EPA, the potential health issues vary and are dependent upon the types and concentrations of the chemicals.  The length of exposure to the chemicals and the overall health of those being exposed are additional factors that determine how building occupants will react. 


The redevelopment of brownfield sites can also create situations for potential vapor intrusion issues for any new buildings.  Brownfield developers must manage environmental risk, especially those due to potential vapor intrusion issues.


Clark Seif Clark, a leading provider of vapor intrusion assessments, has decades of experience handling complex IAQ cases and finding solutions.  “On a case-by-case basis CSC selects from their wide array of sampling technologies and strategies to measure the vapor contaminates of concern,” reported Derrick A. Denis, V.P. Indoor Environmental Quality at CSC.  “Based on the results of our investigation, CSC provides valuable information to assist building owners in protecting both their structure and the health of the occupants.”  In some cases, a risk assessment is performed to establish whether indoor air testing is necessary.
