Abstract

Improved monitoring of potable water is essential if we are to achieve the UN Sustainable Development Goals (SDGs), specifically SDG6: to make clean water and sanitation available to all. Typically monitoring of potable water requires laboratory analysis to detect indicators of fecal pollution, such as thermotolerant coliforms (TTCs), Escherichia coli (E. coli), or intestinal enterococci. However, these analyses are time‐consuming and expensive, and recent advances in field deployable sensing technology offer opportunities to investigate both the spatial and temporal dynamics of microbial pollution in a more resolved and cost‐effective manner, thus advancing process‐based understanding and practical application for human health. Fluorescence offers a realistic proxy for monitoring coliforms in freshwaters with potential for quantification of potable water contamination in near real‐time with no need for costly reagents. Here, we focus on E. coli to provide a state‐of‐the‐art review of potential technologies capable of delivering an effective real‐time E. coli sensor system. We synthesize recent research on the use of fluorescence spectroscopy to quantify microbial contamination and discuss a variety of approaches (and constraints) to relate the raw fluorescence signal to E. coli enumerations. Together, these offer an invaluable platform to monitor drinking water quality which is required in situations where the water treatment and distribution infrastructure is degraded, for example in less economically developed countries; and during disaster‐relief operations. Overall, our review suggests that the fluorescence of dissolved organic matter is the most viable current method—given recent advances in field‐deployable technology—and we highlight the potential for recent developments to enhance approaches to water quality monitoring.

饮用水中微生物污染定量研究进展:荧光传感技术的潜力
如果我们要实现联合国可持续发展目标(sdg),特别是可持续发展目标6:为所有人提供清洁水和卫生设施,改进饮用水监测至关重要。通常对饮用水的监测需要实验室分析,以检测粪便污染的指标,如耐热大肠菌群(TTCs)、大肠杆菌(E. coli)或肠道肠球菌。然而,这些分析既耗时又昂贵,而现场可部署传感技术的最新进展为研究微生物污染的时空动态提供了机会,以一种更解决和更具成本效益的方式,从而推进基于过程的理解和对人类健康的实际应用。荧光为监测淡水中的大肠菌群提供了一种现实的代理,具有近实时的饮用水污染定量潜力,无需昂贵的试剂。在这里,我们将重点放在大肠杆菌上,以提供能够提供有效的实时大肠杆菌传感器系统的潜在技术的最新综述。我们综合了利用荧光光谱来量化微生物污染的最新研究,并讨论了将原始荧光信号与大肠杆菌计数联系起来的各种方法(和限制)。总之,这些提供了监测饮用水质量的宝贵平台,这是在水处理和分配基础设施退化的情况下所需要的,例如在经济较不发达的国家;在救灾行动中。总的来说,我们的综述表明,鉴于现场可部署技术的最新进展,溶解有机物的荧光是目前最可行的方法,我们强调了最近发展的潜力,以加强水质监测方法。
