本文件提供了以下方面的指导: -对已知存在土壤污染或怀疑存在土壤污染的现场进行调查； -调查预计不会出现土壤污染，但需确定土壤质量的现场（例如，确保不存在污染）； -预计需要对可能受到污染的挖掘土壤进行再利用或处置的调查； -收集风险评估和/或制定补救行动计划所需的信息（例如，是否需要补救，以及如何最好地实现补救的建议）。 虽然风险评估和/或补救行动计划制定所需的土壤质量信息是通过应用本文件收集的，但本文件并未对现场调查后的决定和行动提供指导，例如，风险评估和有关补救要求的决定（如有）。

This document gives guidance on the: — investigation of sites, where either it is known that soil contamination is present, or the presence of soil contamination is suspected; — investigation of sites where no soil contamination is expected, but the soil quality is to be determined (e.g. to make sure that there is no contamination present); — investigation in anticipation of a need to manage re-use or disposal of excavated soil which might be contaminated; — collection of information that is necessary for risk assessment and/or the development of remedial action plans (e.g. whether remediation is required and suggestions as to how this might be best achieved). Although the information on soil quality for the risk assessment and/or the development of remedial action plans is gathered by applying this document, it does not give guidance on the decisions and actions that follow from a site investigation, for example, risk assessment and decisions about the requirements for remediation (if any).
