Vapour intrusion occurs when vapours from contaminated soil migrate upwards. Volatile organic compounds (VOCs) found in ground gas, soils or groundwater are a source of potentially harmful vapours that can infiltrate overlying buildings and homes. This can result in a health and safety risk to receptors and occupants. It is essential that the vapour intrusion pathway is assessed, and mitigation measures applied if required.
