本文件提供了在调查、修复（如果需要）和任何后续施工或工程的各个阶段开发和使用概念性场地模型（CSM）的指导。 它描述了CSM是什么、它们的用途以及它们的成分。它强调了对CSM开发的迭代和动态方法的需要。 本文件旨在供所有参与开发CSM的人员以及依赖使用CSM的人员使用，如监管机构、土地所有者、开发商和公众（以及其他相关方）。理想情况下，这包括调查和补救过程所有阶段的代表，例如初步评估、详细调查、基线人类健康和环境风险评估、可行性研究，以及任何后续施工或工程。 注1:本文件适用于存在“潜在有害”或“有害”物质的情况，无论这些物质是自然产生的还是由于人类活动而存在的（即“污染物”）。 注2:尽管本文件中描述的开发CSM的大多数原则可适用于其他领域，如地下水资源管理，但本文件专门针对潜在污染场地或已知污染场地的管理而编写。

This document provides guidance on developing and using conceptual site models (CSMs) through the various phases of investigation, remediation (if required), and any subsequent construction or engineering works. It describes what CSMs are, what they are used for and what their constituents are. It stresses the need for an iterative and dynamic approach to CSM development. This document is intended to be used by all those involved in developing CSMs and by those who rely on using them such as regulators, landowners, developers, and the public (and other relevant parties). Ideally, this includes representatives from all phases of the investigative and remedial processes, for example, preliminary assessment, detailed investigation, baseline human health and environmental risk assessments, and feasibility study, and, any subsequent construction or engineering work. NOTE 1 This document is applicable whenever the presence of "potentially harmful" or "hazardous" substances are present irrespective of whether they are naturally occurring or present due to human activity (i.e. are "contaminants"). NOTE 2 Although most of the principles described for developing CSMs in this document can apply to other domains, such as groundwater resources management, the present document is specifically written for the management of potentially contaminated sites or known contaminated sites.
