Soil Vapor Intrusion Investigation

Indoor Air Quality (IAQ)

CORE provides Soil Vapor Intrusion Investigations for commercial and development properties. The phrase "soil vapor intrusion" refers to the process by which volatile chemicals migrate from a subsurface source into the indoor air of buildings. CORE follows the Guidance for Evaluating Soil Vapor Intrusion in the State of New York, to ensure compliance with the NYSDOH and NYSDEC. Our experienced team of Vapor Intrusion specialists can assist you with all remediation aspects of the project including sampling & analysis and final reporting.

Sites at which an investigation is appropriate

Data collected to date do not support the use of pre-determined concentrations of volatile chemicals (i.e., screening criteria) in either groundwater or soil to trigger a soil vapor intrusion investigation. Therefore, although the level of investigation may vary, the pathway should be investigated at any site with the following:

a. an existing subsurface source (e.g., on the basis of preliminary environmental sampling) or likely subsurface source (e.g., on the basis of known previous land uses) of volatile chemicals [Section 1.1]; and

b. existing buildings or the possibility that buildings may be constructed near a subsurface source of volatile chemicals.
