Drinking water in Germany is subject to strict quality control by communal water suppliers up to a certain point in the pipework, typically at an outside stop valve. The parameters of the water quality are regularly analyzed and the results are thoroughly documented and made accessible to the public. However, some parameters of the drinking water may change due to interactions with pipes and fittings, and the extent of these changes is not yet fully understood by either scientists or citizens. Scientists lack access to the water samples, while citizens may not have access to the measurement methodology.

To address this research gap, the CS:iDrop citizen science research project was launched in Bochum, which aims to investigate the chemical parameters of drinking water with the help of citizens, scientists, and municipal partners. One of the project's objectives is to determine whether differences exist between water meter readings and tap water quality in private households for selected chemical parameters. Citizens can participate in the CS:iDrop project by attending regular development and evaluation workshops. Through ongoing exchange, citizen researchers are actively engaged in the further development of the project.
