美国和欧洲已经报告了许多饮用水污染事件，这些事件是由于有机化学品通过水管组件渗透到土壤中造成的。本文作者将垫片材料样品浸入汽油和溶剂中，并将实际的垫片管段暴露于汽油和溶剂中，以确定各种垫片类型对渗透的敏感性。使用气相色谱法定期分析密封管段内的水，以确定是否存在汽油或溶剂。 还对垫圈材料进行了分析，以检测变化。这些暴露试验的结果用于估计因渗透垫片材料而导致的管道水中污染物的浓度。包括10个参考文献、表格和图表。

Numerous incidents of drinking water contamination resulting from permeation of organic chemicals in soil through water piping components have been reported in the United States and Europe. The authors of this article immersed samples of gasket materials in gasoline and solvents and exposed actual gasketed pipe segments to gasoline and solvents to determine the susceptibility of various gasket types to permeation. Water inside gasketed pipe segments was analyzed at regular time intervals for the presence of gasoline or solvent using gas chromatography. The gasket material was also analyzed to detect changes. The results of these exposure tests were used to estimate the concentration of contaminants in the pipe water resulting from permeation through the gasket materials. Includes 10 references, tables, figures.
