Association is developing guidance aimed at designers, developers and clients for managing volatile chemicals in the ground

Guidance for assessing and managing the risk to human health from volatile chemicals in the ground is being developed by the Construction Industry Research and Information Association (CIRIA). Written to be consistent with the existing UK Contaminated Land Regime, it will also provide additional information on guidance from DRFRA and the Environment Agency that is currently being developed.

The guidance will cover a number of areas including the determination of: the extent of contamination around and under the building; the soil properties relevant to assessing the potential of vapour intrusion; the vapour concentration in the ground; and how to interpret data to assess the risk.

The finished guidance is aimed at design consultants, developers and clients. To understand and improve on current practice for investigating volatile compounds on brownfield sites CIRIA has produced a questionnaire. Anyone who wants a copy should contact Joanne Kwan, CIRIA project manager, on 020 7549 3300.
