Contaminated Land Exposure Assessment (CLEA)

These pages are currently being updated.  New information will be available here when we publish our revised guidance.

The Department for Environment, Food and Rural Affairs (Defra) and the Environment Agency published a series of reports that provide a scientifically based framework for the assessment of risks to human health from land contamination.

By providing a consistent approach to risk assessment, the framework will help the rapid identification of sites that pose a significant risk to human health and help avoid blight on other sites. The framework does not consider risks to other receptors such as plants and animals, buildings, and controlled waters.

On the pages below you will find an introduction to the CLEA model, Health Criteria Values (TOX reports) and the Soil Guideline Values (SGVs), as well as answers to frequently asked questions (FAQ):
