Soil Guideline Values
UK Soil Guideline Values (SGVs) provide a coherent and consistent way to assess risk to human health from soil contamination  . The values can be used to assess land in conjunction with UK legislation: Part IIA of the Environmental Protection Act 1990 and the Town and Country Planning Acts. Any decisions using these values can be seen as being based on sound science. This has become increasingly important as classing land as contaminated can blight an area and cause public concern over the health effects.
These soil guideline values completely supersede the old ICRCL (Interdepartmental Committee on the Redevelopment of Contaminated Land) values. Values are compiled by modelling human exposure with the use of the land known as Contaminated Land Exposure Assessment (CLEA). This creates separate values for:
The first values were published by the Environment Agency on the 2002-03-14 and totalled 10. There are plans for more to be published in the future as research projects are completed .
The current Soil Guideline Values are (all amounts are in mg kg-1 dry weight soil):
SGV3 Cadmium pH 6 pH 7 pH 8
SGV5 Inorganic Mercury
SGV8 Phenol 1%SOM 2.5% SOM 5% SOM
SGV15 Toluene 1%SOM 2.5% SOM 5% SOM
SGV16 Ethylbenzene 1%SOM 2.5% SOM 5% SOM
