The United Nation's Sustainable Development Goal 6.1 seeks to achieve universal and equitable access to safe and affordable drinking water for all. While global access to improved drinking water sources has been expanding over the past decades, it is still lacking in many places, especially in sub-Saharan Africa. Furthermore, not all improved drinking water sources are safe. Water quality monitoring at the point of use is quintessential for the provision of safe water.This project will develop innovative technologies for rapidly surveying, mapping and communicating waterborne hazards. Newcastle University in the UK will team up with Ardhi University in Tanzania, for the method development with subsequent field testing in Dar es Salaam, with the aim of establishing all methods and skills in the partner country Tanzania by the end of the project. The project will develop portable gene sequencing equipment as a versatile technology to comprehensively assess microbial water quality within a matter of hours. It will embed this molecular microbiological method with other field deployable methods for assessing water quality, including inexpensive screening methods, to derive cost effective and reliable surveying strategies.The water quality assessment methods will be integrated with digital technologies for data storage in a remote database, and immediate data curation, interpretation and visualization, firstly to assist surveyors with their field work, and secondly to make surveying data accessible to the public. A hazard communication tool will be developed with location aware, multi-platform hazard maps, augmented by in-app links to a repository of contextual information, including health impacts, practical advice, observational metadata and WHO information. The development will be "mobile-first" such that designs fit a variety of mobiles and tablets. The use of CSS and modern browser technology will ensure that the same applications can be deployed automatically to multiple devices with the content being dynamically selected (or reduced) depending on the device capabilities.The water quality surveying equipment and methods, together with the associated digital technologies, will be field-tested in four surveys of increasing complexity of different water sources in unplanned settlements in Dar es Salaam, Tanzania. According to UNICEF, 46% of Tanzanians still lack access to improved drinking water sources. Waterborne diseases are endemic in Tanzania and a major disease burden, as evidenced by the major cholera outbreak in Dar es Salaam and other Tanzanian regions in the summer and autumn of 2015, which affected thousands of people. In this project, local stakeholders like the Dar es Salaam Water & Sewerage Authority, school teachers and community representatives will be engaged in the technology development and testing, helping in particular with the identification of context-appropriate, useful hazard communication methods. Multiple visual waterborne hazard display options will for example be scrutinized by these stakeholders to explore their social acceptability as well as easy interpretability and usefulness. Ardhi University researchers will assist with the translation of key contextual information into local languages.The methods and technologies developed in this project will not only facilitate water quality monitoring and communication in low income countries like Tanzania, where waterborne diseases are a significant health burden, but they will also facilitate the emergency response to natural or human-made disasters such as major earthquakes, the displacement of people by conflicts, or terrorist attacks affecting water supplies.

联合国可持续发展目标 6.1 力求实现人人普遍、公平地获得安全、负担得起的饮用水。尽管过去几十年来，全球获得改善的饮用水源的机会不断增加，但许多地方仍然缺乏，特别是在撒哈拉以南非洲地区。此外，并非所有改良的饮用水源都是安全的。使用点的水质监测是提供安全用水的关键。该项目将开发创新技术，用于快速测量、测绘和传达水传播危害。英国纽卡斯尔大学将与坦桑尼亚阿尔迪大学合作，进行方法开发，并随后在达累斯萨拉姆进行现场测试，目标是在项目结束时在伙伴国坦桑尼亚建立所有方法和技能。该项目将开发便携式基因测序设备作为一种多功能技术，可在数小时内全面评估微生物水质。它将把这种分子微生物学方法与其他可现场部署的水质评估方法（包括廉价的筛选方法）结合起来，以得出具有成本效益且可靠的测量策略。水质评估方法将与数字技术相结合，用于远程数据库中的数据存储，以及即时数据管理、解释和可视化，首先是为了协助测量员进行现场工作，其次是为了向公众提供测量数据。将开发具有位置感知、多平台危险地图的危险沟通工具，并通过应用程序内链接到背景信息存储库进行增强，包括健康影响、实用建议、观察元数据和世卫组织信息。该开发将“移动优先”，以便设计适合各种手机和平板电脑。 CSS和现代浏览器技术的使用将确保相同的应用程序可以自动部署到多个设备，并根据设备功能动态选择（或减少）内容。水质测量设备和方法以及相关的数字技术将在坦桑尼亚达累斯萨拉姆非规划定居点的不同水源日益复杂的四次调查中进行现场测试。据联合国儿童基金会称，46% 的坦桑尼亚人仍然无法获得改善的饮用水源。水传播疾病是坦桑尼亚的地方病，也是一个重大的疾病负担，2015 年夏季和秋季达累斯萨拉姆和坦桑尼亚其他地区爆发的霍乱疫情就证明了这一点，该疾病影响了数千人。在该项目中，达累斯萨拉姆供水和污水处理局、学校教师和社区代表等当地利益相关者将参与技术开发和测试，特别是帮助确定适合具体情况的有用的危险沟通方法。例如，这些利益相关者将仔细审查多种视觉水载危险显示选项，以探索其社会可接受性以及易于解释性和实用性。阿迪大学的研究人员将协助将关键背景信息翻译成当地语言。该项目开发的方法和技术不仅将促进坦桑尼亚等低收入国家的水质监测和通信（水传播疾病是这些国家的重大健康负担），还将促进对自然或人为灾害的紧急响应，如大地震、冲突造成的人员流离失所或影响供水的恐怖袭击。
