How is Sub-Slab Soil Gas Sampling Done? {Infographic}

November 21, 2017

Vapor Intrusion occurs when vapors from volatile chemicals in contaminated soil or ground water migrate through subsurface soils and/or preferential pathways (such as underground utilities) and impact the indoor air quality of any overlying buildings.*

Recent advancements in toxicological science and inclusion in the ASTM E1527-13 guiding Phase I Environmental Site Assessments have placed priority on evaluating Vapor Intrusion pathways. Regulators across the county are increasing requirements for sampling these pathways.

Sub-slab soil gas sampling is used in existing buildings that may have or be near sources of Vapor Intrustion contaminates.
