A recognized researcher and consultant, Dr. Mehrdad Javaherian has contributed his expertise in the remediation of chemical contamination to a wide range of organizations. As a consulting health assessor and epidemiologist for the California Department of Public Health and the Agency for Toxic Substances and Disease Registry, Dr. Mehrdad Javaherian led the evaluation of potential public health impacts due to indoor intrusion of tetrachloroethene (PCE) vapors across the City of Modesto, CA. He has also worked extensively on mathematical formulation of models used to simulate vapor intrusion processes.
Vapor intrusion is a process that involves volatile chemicals, such as petroleum hydrocarbons or cleaning solvents, migrating from the subsurface into the buildings above. According to the Interstate Technology & Regulatory Council, vapor intrusion is dependent on three elements: a source, a pathway, and an inhabited structure. The spread of volatile chemicals has become an environmental concern for residents and regulators who worry about the health impacts of indoor air quality degradation.
Depending on the degree of vapor intrusion at a site, investigators may call for remediation efforts or rapid regulatory action in response to subsurface contamination. A number of health organizations are working to improve awareness about the importance of indoor air sampling and assessment to combat the potential health risks associated with vapor intrusion.
