1.1本规程涵盖了为获取环境数据而制定数据质量目标（DQOs）的过程。采样和分析设计的优化是DQO过程的一部分。本实践详细描述了DQO过程。设计优化的各种策略太多，无法包含在本实践中。许多其他文件概述了优化采样和分析设计的替代方案。因此，仅包括设计优化概述。为了便于说明，实践示例中包含了一些设计方面。 1.2 DQO开发是数据生成活动三部分中的第一部分。另外两个方面是( 1. )采样和分析策略的实施，见指南D 6311和( 2. )数据质量评估，见指南D 6233。 1.3本指南应与规程D 5283、D 6250和指南D 6044配合使用。实践D 5283概述了规划期间规定和实施期间使用的质量保证（QA）过程。指南D 6044概述了从人群中获得代表性样本的过程，确定了可能影响代表性的来源，并描述了代表性样本的属性。实践D 6250描述了如何计算决策点。 1.4与废物管理活动有关的环境数据包括但不限于空气、土壤、水、生物群、过程或一般废物样品或其任何组合的采样和分析结果。 1.5 DQO过程是一个规划过程，应在采样和分析活动之前完成。 1.6本规程提出了广泛的管理要求，旨在确保高质量的环境数据。措辞“必须”和“应”（要求）、“应”（建议）和“可”（可选）经过仔细挑选，以反映本实践中对许多陈述的重视。满足所有要求的程度仍然是一个技术判断问题。 1.7以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.8 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 This practice covers the process of development of data quality objectives (DQOs) for the acquisition of environmental data. Optimization of sampling and analysis design is a part of the DQO process. This practice describes the DQO process in detail. The various strategies for design optimization are too numerous to include in this practice. Many other documents outline alternatives for optimizing sampling and analysis design. Therefore, only an overview of design optimization is included. Some design aspects are included in the practice's examples for illustration purposes. 1.2 DQO development is the first of three parts of data generation activities. The other two aspects are ( 1 ) implementation of the sampling and analysis strategies, see Guide D 6311 and ( 2 ) data quality assessment, see Guide D 6233. 1.3 This guide should be used in concert with Practices D 5283, D 6250, and Guide D 6044. Practice D 5283 outlines the quality assurance (QA) processes specified during planning and used during implementation. Guide D 6044 outlines a process by which a representative sample may be obtained from a population, identifies sources that can affect representativeness and describes the attributes of a representative sample. Practice D 6250 describes how a decision point can be calculated. 1.4 Environmental data related to waste management activities include, but are not limited to, the results from the sampling and analyses of air, soil, water, biota, process or general waste samples, or any combinations thereof. 1.5 The DQO process is a planning process and should be completed prior to sampling and analysis activities. 1.6 This practice presents extensive requirements of management, designed to ensure high-quality environmental data. The words "must" and "shall" (requirements), "should" (recommendation), and "may" (optional), have been selected carefully to reflect the importance placed on many of the statements in this practice. The extent to which all requirements will be met remains a matter of technical judgment. 1.7 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.8 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 and health practices and determine the applicability of regulatory limitations prior to use.
