Vapor Intrusion & Soil Vapor Testing

Vapor Intrusion & Soil Vapor Testing A vapor intrusion investigation entails the study of toxic soil gases that migrate through the subsurface and into the living spaces of structures aboveground. Geologists perform soil vapor tests to evaluate the presence of vapor-phase contamination underground. Additionally, the chemical content of the vapor samples is examined for toxicity…
