Vapor Intrusion Characterization and Monitoring from SGS

Fully characterize and monitor your site with the help of our state-of-the-art delineation tools and regulatory compliant analytical capabilities

Potentially toxic and carcinogenic vapors can accumulate in indoor air in buildings near or on top of a contaminated site. These substances, which can include chlorinated volatile organic compounds [CVOCs], petroleum products and polycyclic aromatic hydrocarbons [PAHs], pose risks to human health through inhalation. Vapor intrusion monitoring and characterization is essential for preventing such health risks and ensuring compliance with regulations. 

Why choose vapor intrusion characterization and monitoring from SGS? 

Testing for vapor intrusion is complicated by temporal and spatial variability. This means that a multiple lines of evidence (MLE) approach is needed to properly interpret results and make decisions. 

Our direct read instruments, variety of sampling equipment and analytical capabilities will help you to complete an MLE investigation from site characterization to site closeout.
