Groundwater Monitoring through Citizen Science: A Review of Project Designs and Results

Abstract

Citizen science is increasingly prominent in the field of freshwater monitoring. Although there is a large body of literature related to surface water monitoring, less experience exists regarding citizen-based monitoring of groundwater resources. This calls for a better understanding of the actual experiences of citizen science in the field of groundwater monitoring, including specific project designs and results. Based on a systematic review of 33 citizen-based groundwater monitoring activities, we analyze (1) the design of citizen science projects, including their general project characteristics, institutional characteristics, citizen characteristics, and forms of interactions, as well as (2) their results, including their data outputs, outcomes on citizens, and impacts on problem-solving. Results show that projects mainly have positive results on data quantity and quality and partly influence the citizens themselves and their contributions to groundwater-related problem-solving. Information on project design characteristics is scarce and mostly hints at the relevance of specific process mechanisms such as training and feedback. Based on these results, we suggest groundwater-related projects to consider involving citizen scientists in monitoring activities in order to benefit research and citizens alike. Such involvement needs, however, careful design including relevant training to unfold its full potential for both sides. Researchers are advised here to rigorously report on both design and results to further improve citizen science practice in the future.

An overview of groundwater response to a changing climate in the Murray-Darling Basin, Australia: potential implications for the basin system and opportunities for management

“…Building on existing systems (Sharples et al 2020), sharing data across scales would be supported by frameworks for landholders to share data and observations of groundwater levels and groundwater system behaviour such as responses of surface water and GDEs to changes in groundwater. This has the potential to build on citizen science efforts (Nath and Kirschke 2023;Walker et al 2021a), especially related to mining and energy developments (Jamieson et al 2020) where there is a large amount of currently unavailable knowledge and data. Quality assurance, fair payment for information sharing, fair sharing of the costs and benefits of new information, and the development of protocols for minimum standards for data sharing would need to be part of this process.…”

“First alert” for Drinking Water Quality: Commercial Water Quality Testing Kits for Community-Engaged Research

“…The framework is iterative and continuous, strengthening the research questions, outcomes, and community-driven solutions . The CEnR framework is commonly applied to monitor water quality, but most of these efforts are focused on surface water. − For example, the Alabama Water Watch (AWW) was established in 1992 and, through the program, citizens are trained to monitor conditions and trends in local waterbodies . The AWW data has been used by researchers, policymakers, and other stakeholder groups to improve water quality on a state-wide scale for over 30 years.…”

How well can people observe the flow state of temporary streams?

“…Citizen science projects can obtain high spatial resolution data, even in remote areas (Weeser et al, 2018), and thus provide an excellent opportunity to collect hydrological data (Lowry and Fienen, 2013;Njue et al, 2019). Citizen scientists have observed water levels (Lowry and Fienen, 2013;Weeser et al, 2018), flood heights and extents (See, 2019;Sekajugo et al, 2022), groundwater levels (Little et al, 2016;Nath and Kirschke, 2023), water quality (Capdevila et al, 2020;Blanco-Ramírez et al, 2023), plastic pollution (Cook et al, 2021;Syberg et al, 2020), and also the state of temporary streams (Turner and Richter, 2011;Kampf et al, 2018;Allen et al, 2019;Truchy et al, 2023). Citizen science projects for temporary streams record the flow state with a visual approach (i.e., they do not use any measurement devices, except for a global positioning system (GPS) or a smartphone).…”
