This is an introduction to soil guideline values (SGV) used in land contamination assessment. It explains what SGVs are, their purpose and advice on their use.
SGVs and the framework documents provide scientifically based information on the assessment of risks to human health from land contamination. They provide non-statutory technical guidance to regulators and their advisors in support of the statutory regimes addressing land contamination, particularly Part 2A of the Environmental Protection Act 1990 and the consideration of land affected by contamination under the Town and Country Planning Acts.
Technical notes and supporting information showing SGVs for different chemicals are listed at Land contamination: soil guideline values (SGVs).
