标准摘要
[中文适用范围]： 此文件提供了修复技术关键方面的要求和指导。它描述了在个别或组合选择原位和异位修复技术时应考虑的原则、主要特征、优势和局限性，包括：——需要处理的污染物类型；——当前或预期场地用途；——当地的法律法规、政策、社会经济和环境背景。此文件适用于受污染场地的修复，即土壤、土壤气体、大气或地下水受到污染的情况。该文件指出了技术可以针对的相/态，例如流体（地下水、气体、非水相液体）或固体，并指出它适用于哪些污染物。此外，该文件还提供了与实施修复相关的风险信息。此文件未提供：——一个详尽的修复技术列表；——受放射性物质、病原或传染性剂或“火药装置”（如未爆炸弹药）污染场地的指导；——离场技术的指导，这些技术在场外设置；——涵盖所有个别情况的框架，或规定特定背景下应使用哪种技术。 [外文原描述]： This document provides requirements and guidance on key aspects of remediation techniques. It describes the principles, main characteristics, advantages and limitations to be considered in the selection within an option appraisal of individual or combinations of in situ and on-site remediation techniques, including: — the type of contaminants to be dealt with; — current and/or intended site use; — local legal, policy, socio-economic and environmental contexts. This document is applicable to the remediation of contaminated sites, i.e. where soil, or soil gas, ambient air or groundwater are contaminated. It identifies which phase/matrix can be targeted by a technique, e.g. fluid (groundwater, gas, non-aqueous phase liquid) or solid, and which contaminant it can applied to. This document also provides information on hazards that can be associated with the implementation of remediation. This document does not provide: — an exhaustive list of remediation techniques; — guidance on sites contaminated with radioactive substances, pathogenic or infectious agents, or “pyrotechnic devices” (e.g. unexploded ordnances); — guidance on ex situ techniques that are set up off-site; — a framework that covers all individual situations, or prescribes which technique(s) to use in a specific context.
