Vapor Intrusion Assessment and Monitoring

    Volatile chemicals in soil or groundwater sometimes migrate into buildings, resulting in a Vapor Intrusion Condition. Even at low concentrations, the presence of some volatile compounds may pose a health concern to building occupants. Therefore, G|E|M performs a risk assessment for vapor concerns with every Phase I Environmental Site Assessment. When potential concerns are identified, G|E|M will design accurate, cost-effective monitoring solutions to obtain reliable results for evaluation.
