Citizen science tools for engaged research: Water quality monitoring in remote communities

Abstract

Remote areas that lack conventional water-provisioning infrastructure often rely on rainwater harvesting, rivers, pans, reservoirs and borehole-extracted water to meet domestic water requirements. These water sources often have poor microbial quality and chemical composition, the quality of which is not routinely monitored. This study explored citizen science as a tool for Engaged Research and Responsible Research and Innovation, detailing the co-creation of a sustained community-based water quality monitoring program in collaboration with communities in villages in Amakhala Game Reserve (Eastern Cape, South Africa). Without access to other water sources, participants predominantly used rainwater for drinking and cooking (80%), while borehole water was mainly used for cleaning and gardening due to its salty or bitter taste. A hydrogen sulfide (H2S) water testing kit was used by the citizen scientists to monitor the water quality. The H2S kits were effective in estimating bacterial contamination, showing a proportional relationship with Colilert® test results conducted in a laboratory. The alignment observed between community-based monitoring results and those derived from scientist-led testing underscores the value of data produced through citizen science initiatives. Sustained participant engagement throughout this research reflected a sense of community empowerment through access to tools that inform their decision-making around water use and treatment as well as investment in the research, indicative of the perceived relevance of the research to community interests. This integration of transdisciplinary data sources holds promise for informing evidence-based decision-making processes, facilitating more effective and contextually informed water management strategies that value and integrate community perspectives alongside scientific insights. Significance: Drawing on the principles of Engaged Research and Responsible Research and Innovation, we applied citizen science tools to engage researchers and communities in the co-development of a water quality monitoring program. In addressing a specific area of concern, raised by the remotely situated community around the need for knowing their water quality, the project successfully trained communities in applying water testing tools and fostered agency in decision-making around water treatment. Combined with continuous feedback and communication loops, a high rate of continuity was sustained among the participants.
