Answer B: An investigation of whether volatile organic compounds (VOCs) from contaminated soil or groundwater are migrating into building air, potentially creating indoor air quality hazards

Vapor intrusion occurs when volatile chemicals in contaminated soil or groundwater vaporize and migrate through the soil into building foundations. VOCs from underground sources (dry cleaners, gas stations, industrial sites) can create serious indoor air quality hazards.
