This paper provides a view on the suitability of screening-level vapour intrusion (VI) algorithms for contaminated land management. It focuses on the accuracy and level of conservatism for a number of screening-level algorithms used for VI into buildings. The paper discusses the published evidence of the accuracy of VI algorithms and puts the conservatism is a broader regulatory perspective, including advice on how to deal with variation. In closing further research needs are provided.
