这项工作的动机是与直接饮用水回用（DPR）相关的技术进步和考虑替代水资源时公共价值的重要性。这项研究涉及向美国四个城市的居民分发关于现有自来水供应和“净化水”的在线调查，“净化水”被定义为“经过先进水处理工艺的城市废水，从而使水质至少符合饮用水法规”。总体而言，50-60%的受访者支持使用纯净水作为饮用水。目前自来水和纯化水中的味道/气味和微生物污染物的污染问题最高。调查结果强调了在向公众宣传DPR时解决某些领域的重要性，例如防止微生物污染的障碍，公用事业的可信赖性，对现状的潜在改进，以及在给定环境中需要使用纯净水的社区特定驱动因素。
This work is motivated by technical advancements related to direct potable reuse (DPR) and the importance of public values when considering alternative water resources. This study involved the distribution of an online survey to residents in four US cities about existing tap water supplies and “purified water,” defined as “municipal wastewater that has undergone advanced water treatment processes, thus resulting in water quality that, at a minimum, complies with drinking water regulations.” Overall, 50–60% of respondents were in support of using purified water as potable water. Contaminant concerns were highest for taste/smell and microbial contaminants in both current tap water and purified water. Survey results highlight the importance of addressing certain areas when communicating about DPR to the public, such as barriers against microbial contamination, the trustworthiness of utilities, potential improvements over the status quo, and community‐specific drivers that necessitate the use of purified water in a given setting.
