Abstract

Increasing access to water quality tests in low-income communities is a crucial strategy toward achieving global water equality. Recent studies in the Water Sanitation and Hygiene (WASH) sector underscore the importance of addressing practical concerns in water testing, such as robustness and results communication. In response, we present the WaterScope testing kit; an open-source, validated platform for drinking water quality assessment. It modernises the testing process with the inclusion of a unique cartridge/slider mechanism, machine-learning-enhanced classification and full digitalisation of results. WaterScope’s equivalency to conventional methods for quantifying E. coli is established through extensive validation experiments in both laboratory and field environments. This versatile platform provides potential to expand its applications to test other bacteria, perform colorimetric assays, and analyse clinical samples such as blood/urine samples. We anticipate that the system’s ease-of-use, portability, affordability, robustness, and digital nature will accelerate progress toward global water equality.

利用开源 WaterScope 测试平台扩大水质监测范围
在低收入社区增加水质检测机会是实现全球水资源平等的一项重要战略。水、环境卫生和个人卫生(WASH)领域的最新研究强调了解决水质检测中的实际问题(如稳健性和结果交流)的重要性。为此,我们推出了 WaterScope 测试工具包;这是一个开源、经过验证的饮用水质量评估平台。它采用独特的滤芯/滑块机制、机器学习增强型分类和结果完全数字化,使检测过程实现了现代化。通过在实验室和现场环境中进行广泛的验证实验,确定了 WaterScope 与传统大肠杆菌定量方法的等效性。这一多功能平台具有扩展应用的潜力,可用于检测其他细菌、执行比色测定以及分析血液/尿液等临床样本。我们预计,该系统的易用性、便携性、经济性、坚固性和数字化特性将加快全球水资源平等的进程。
