Progress in hydrological science and water resource management is largely limited by the rate at which water quality data can be collected and transformed into actionable information. Water quality data is needed to understand the overall health of water bodies and the underlying physical, chemical, biological, and ecological processes so that resource managers can make well-informed decisions. In recent studies, spectroscopy-based sensing technologies have been used to generate high-frequency data for multiple water quality parameters. While several devices designed to perform in situ spectroscopy are currently available off-the-shelf, their broad use is limited by cost (in the range of $20,000) and lack of control over how the system operates and manages data. Recent technological advancements have enabled investigators to custom build spectroscopy-based in situ water quality data collection systems. A low-cost (~$2,500) benchtop prototype was developed which can detect multiple water quality parameters using a miniature spectrophotometer and light source housed in a 3D-printed enclosure and controlled using a microcomputer. In the future, this system will be adapted to perform high-frequency collection of water quality data, in situ, and used to investigate the effects of data collection frequency on hydrological model performance in urban settings and to analyze nutrient dynamics within urban stormwater infrastructure. Beyond the goals of this study, the same data collection framework can be used in future applications that require highly controlled in situ water quality data collection, such as adaptive control of stormwater systems, watershed fingerprinting, and improving pollutant detection through advanced statistical techniques.
