This report summarizes the current state of knowledge on the persistence of chemical contamination on drinking water infrastructure (such as pipes) along with information on decontamination should persistence occur. Decontamination options for drinking water infrastructure have been explored for some chemical contaminants, but important data gaps remain. In general, data on chemical persistence on drinking water infrastructure is available for inorganics such as arsenic and mercury, as well as select organics such as petroleum products, pesticides and rodenticides. Data specific to chemical warfare agents and pharmaceuticals was not found and data on toxins is scant. Future research suggestions focus on expanding the available chemical persistence data to other common drinking water infrastructure materials. Decontaminating agents that successfully removed persistent contamination from one infrastructure material should be used in further studies. Methods for sampling or extracting chemical agents from water infrastructure surfaces are needed.
本报告总结了目前关于饮用水基础设施（如管道）中化学污染物持续存在的知识状况，并提供了发生持续性污染时的去污信息。已经针对一些化学污染物探索了饮用水基础设施的去污选择，但仍存在重要的数据空白。一般来说，关于饮用水基础设施中无机物（如砷和汞）以及某些有机物（如石油产品、农药和灭鼠剂）化学持久性的数据是可用的。未找到关于化学战剂和药物的确切数据，关于毒素的数据也很少。未来的研究建议侧重于将可用的化学持久性数据扩展到其他常见的饮用水基础设施材料。应在进一步的研究中使用成功从一种基础设施材料中去除持久性污染物的去污剂。需要从水基础设施表面采样或提取化学物质的方法。
