Summary

This guidance note, published jointly with CL:AIRE, provides advice on the use of statistical techniques in the assessment of soil contamination data. It forms one part of the package of improved UK guidance highlighted in Defra’s ‘Soil guideline values: the Way Forward’ discussion paper. Its overall aim is to increase understanding amongst stakeholders of the role that statistics can play in quantifying the uncertainty attached to estimates of the mean concentration of contaminants in soil thereby creating a more informed basis for regulatory decision-making.
