为了控制石棉水泥（A-C）管道的腐蚀，水务公司与管道制造商合作开发了一种内衬A-C管道。内衬的应用通常包括用四氯乙烯（PCE）稀释乙烯基甲苯树脂，并将其喷涂在管道内部。在国家有机物监测调查的后续行动中，美国环境保护局和几个新英格兰州在使用a-C管道的社区的饮用水中发现了残留的PCE。 本文作者描述了内衬A-C管的开发和使用背后的一些历史，停止生产的原因，以及为纠正该问题而采取的措施。美国环境保护局提出的战略包括个人房主可以采取的改善饮用水和烹饪用水的措施，以及社区、州和美国环境保护局可以采取的行动。简要概述了这些策略。两种广泛使用的降低四氯乙烯浓度的方法是冲洗和安装连续放气阀。 包括2个参考文献、表格和图表。

In an effort to control corrosion of asbestos-cement (A-C) pipe, water utilities worked with pipe manufacturers to develop a lined A-C pipe. Application of the lining usually involved thinning the vinyl toluene resin with tetrachloroethylene (PCE) and spraying it on the inside of the pipe. In a follow-up to the National Organics Monitoring Survey, the USEPA and several New England states found residual PCE in the drinking water of communities where lined A-C pipe was being used. The authors of this article describe some of the history behind the development and use of lined A-C pipe, the reasons why its production was discontinued, and actions taken to correct the problem. Strategies suggested by the USEPA include steps that individual homeowners can take to improve water used for drinking and cooking as well as actions that can be taken by communities, states, and the USEPA. These strategies are briefly outlined. Two widely employed methods for lessening tetrachloroethylene concentrations are flushing and installing continuous bleeders.
