对甲基叔丁基醚（MTBE）和其他乙醚进行了全国性调查 美国饮用水源中的汽油氧化物和其他挥发性有机化合物 美国这项调查涉及大量抽样工作，质量控制程序也不完善 用于确保数据的准确性。制定了数据接受策略来评估 从样品瓶的制备到样品采集， 以及实验室分析。进行了两种数据接受策略:初始验证 实验室质量保证/质量控制（QA/QC）；以及现场数据验证 质量保证/质量控制。初始数据验证涉及使用标准实验室对数据进行评估 QA/QC根据检测/报告水平和实验室污染情况审查数据。这个 现场QA/QC的数据验证涉及使用现场空白对数据进行评估，以供审查 随机污染。这些策略提供了一种保守的报告方法 事件研究中的环境数据。包括10个参考文献、表格和图表。

A nationwide survey was conducted of methyl tert-butyl ether (MTBE), other ether gasoline oxygenates, and other volatile organic compounds in drinking-water sources in the United States. This survey involved a large sampling effort and quality-control procedures were utilized to ensure the accuracy of the data. A data acceptance strategy was developed to evaluate all processes of the project from preparation of the sample bottles, through sample collection, and laboratory analysis. Two data acceptance strategies were conducted: initial validation of the laboratory quality assurance/quality control (QA/QC); and, data validation of the field QA/QC. The initial data validation involved evaluation of the data with standard laboratory QA/QC to censor the data based on detection/reporting levels and laboratory contamination. The data validation with field QA/QC involved evaluation of the data with the field blanks to censor for random contamination. These strategies provide a conservative approach to reporting environmental data from an occurrence study. Includes 10 references, table, figures.
