What Are Contaminated Soils?

A large number of development sites have a history of being used for industrial purposes, resulting in the land below and the surrounding environment becoming contaminated. It is estimated that there are up to 20,000 contaminated sites around England and Wales alone that could have a detrimental impact on health and the wider environment. With a recent surge in reclamation and redevelopment, the importance of tackling issues surrounding polluted land and other contamination is more widely understood and is a growing requirement when undertaking a development site.

When working on a development, normal planning practice requires that a survey of any contamination issues is conducted, particularly when the development is considered at risk of contamination or where there is the possibility of contamination to be present. If you are responsible for the health and safety welfare of development, then it is crucial that you come to the experts to ensure that land contamination issues are considered and where necessary, that action is taken, so that the land is suitable for its intended use.
