1.1 本指南涵盖地下水采样事件的规划和准备。它包括技术和行政方面的考虑和程序。示例检查表也作为附录提供。 1.2 本指南可能不涵盖所有地下水取样项目之前所需的所有考虑程序或两者。在岩溶或断裂岩层中，从泉水中采集地下水样本可能是合适的（见指南 D5717年 ). 本指南侧重于从监测井中抽取地下水；然而，本文中的大多数指导也可以应用于弹簧的采样。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本指南提供了有组织的信息收集或一系列选项，不建议采取具体行动。本文件不能代替教育或经验，应结合专业判断使用。并非本指南的所有方面都适用于所有情况。 本ASTM标准不代表或取代必须判断给定专业服务是否充分的谨慎标准，也不应在不考虑项目的许多独特方面的情况下应用本文件。本文件标题中的“标准”一词仅表示该文件已通过ASTM共识程序获得批准。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 3.1 抽样活动的成功取决于充分的规划和准备。使用本指南将有助于地下水采样器有条不紊地执行规划和准备。 3.2 本指南应由具有地下水取样培训或经验的专业人员或技术人员使用。

1.1 This guide covers planning and preparing for a groundwater sampling event. It includes technical and administrative considerations and procedures. Example checklists are also provided as Appendices. 1.2 This guide may not cover every consideration procedure, or both, that is necessary before all groundwater sampling projects. In karst or fractured rock terranes, it may be appropriate to collect groundwater samples from springs (see Guide D5717 ). This guide focuses on sampling of groundwater from monitoring wells; however, most of the guidance herein can apply to the sampling of springs as well. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This guide offers an organized collection of information or a series of options and does not recommend a specific course of action. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this guide may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project's many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 3.1 The success of a sampling event is influenced by adequate planning and preparation. Use of this guide will help the groundwater sampler to methodically execute the planning and preparation. 3.2 This guide should be used by a professional or technician that has training or experience in groundwater sampling.
