| Short description: |
An ecological risk assessment based on the needs of recent UK and EU legislation is described. The framework has been adopted by the UK Environment Agency, with implementation expected in 2005. The UK scheme compares favourably with schemes in other countries, being iterative, tiered and flexible, with agreed exit points subject to satisfying defined criteria.

| Long description: |
The proposed assessment has a tiered approach. The first tier establishes a conceptual site model, where potential source-pathway-receptor linkages are sought and, where identified, lead to the next tier of assessment. This relies largely on a comparison of chemical analysis of soil contaminant levels with soil quality guideline values to assess harm. In some cases biological assessments may also be undertaken. Where harm is identified, a third tier establishes the extent of harm within the ecosystem. Finally, scientifically robust conclusions on the potential for harm within the ecosystem are generated using a ‘weight-of-evidence’ approach.
