Chemicals from any subsurface source into an overlying building. These vapor-forming chemicals may include volatile organic compounds (VOC's), select semi-volatile organic compounds and inorganic compounds chemicals, such as elemental mercury, naturally occurring radon, and hydrogen sulfide.
The vapors may accumulate in dwellings or occupied buildings to levels that may pose an unacceptable risk of health effects due to long-term (i.e., chronic) exposure. The assessment of the risk of health effects is complicated by the potential presence of some of the same chemicals from emission sources within the building including household solvents, cleaners and gasoline.
Circle C Consulting vapor intrusion professionals are highly experienced in successfully assessing and providing vapor intrusion remediation solutions in the most challenging situations.
Prior to each vapor intrusion sampling event, Circle C Consulting personnel conduct a thorough inspection of the building or structure interior (building survey) including:
As necessary, building penetrations are sealed and potential interior vapor sources are removed prior to sample deployment. Results of sampling are evaluated by a Circle C Consulting professional and compared to applicable regulatory criteria.
System design can be completed on existing buildings or structures, new construction, or remodeled buildings. All mitigation systems will be installed by Circle C Consulting professional employees.
