This document provides guidance on the selection and application of screening methods for assessing soil quality and waste characterization, including distribution of target parameters in soil and soil?like material. The aim of this document is to set up criteria as to when the different kind of screening methods can be applied for the analysis of a certain parameter in soil, including soil?like material, and waste, and which steps are required to prove their suitability.

This document does not recommend any particular screening method but confirms the principles of their selection and application.
