“…The most prominent program is linked to the EarthWatch Institute's FreshWater Watch (https:// freshwaterwatch.thewaterhub.org/) where testing kits for nitrate and phosphate are used by trained citizen scientists. The data produced in "WaterBlitz" activities cover wide catchment areas (Hadj-Hammou et al, 2017) and can be used to gauge scale effects such as land use/land cover differences from up to downstream areas (Cunha et al, 2019) on the day of sampling and, with the development of a temporal dataset, over different hydrological conditions. This may be an advantage over statutory methods as a more intensive spatial coverage of nutrient conditions in water can be produced to isolate stepped changes in nutrient water quality from hot spots or hot sub-catchments.…”

This review considers enhanced approaches to river water quality monitoring in north-western Europe following a series of study visits (11 sites in 7 countries). Based on the evidence gathered, options were identified and evaluated for their suitability to deliver specific water quality monitoring objectives and with a focus on effecting behavioral change. Monitoring programs were diverse, ranging from enhanced grab sampling and laboratory analysis to sub-hourly sampling of multiple parameters and nutrients in autonomous high-specification, bank-side or mobile laboratories. Only one program out of all the cases evaluated could readily identify influences that had produced behavioral change among stakeholders. This was principally because the other programs were focused on top-down policy change or surveillance rather than specifically focused on influencing behavior. Nevertheless, program researchers were clear that stakeholder engagement potential was very high and that the sites acted as important focus points for discussion on water quality issues, and so part of a suite of tools that might ultimately change behavior. This identifies a space where water quality monitoring solutions could be adapted for behavioral change research.

“…However, due to limited resolution of sampling, they demonstrate how pooling and integrating data from various sources can remove bias and increase the statistical power of the data. Citizen science data was also used to map nutrient concentrations in water systems in Brazil and Mexico, and to show how these data are critical to guide land use planning and avoid the undesirable consequences of artificial eutrophication [29]. These authors are also clear that such data should only be drawn upon in support of regular monitoring activities, but not to replace official data.…”

Addressing environmental issues in policy making requires recognising these issues as part of a complex socio-ecological system. The evidence base for such policies and associated monitoring and implementation measures, as well as related official indicators, statistics and environmental accounts are receiving increasing attention. This paper explores the potential of citizen science as a non-traditional source of data to complement the current data production process for evidence-based policy-making, using pollution of surface waters and its effect on associated ecosystems as an example. The paper develops a framework that helps to explore the official data production process in relation to different purposes of environmental policies. This highlights different challenges that the current official data production process sees itself confronted with in relation to the different purposes of the policies and associated monitoring regimes. These questions are explored with reference to the case of evidence-based policy making on water quality of surface freshwater in the EU, with a focus on Luxembourg. The analysis is based on extensive documentary analysis and literature review, as well as a series of interviews and participatory workshops with various stakeholders, and first results of a pilot project work with engaged citizen volunteers to solicit data on water quality with a focus on its nutrient content. On this basis, this paper argues that citizen science has the clear potential to meaningfully contribute both to the evidence base for policy and practice, as well as to an improved governance process.

“…Certain factors reinforce the importance of studies aimed at first-order streams, such as their greater occurrence and extension in relation to higher-order rivers (Allen & Pavelsky, 2018;Cunha et al, 2019) and the influence in maintaining the quality offered, including their significant influence on the water quality of large watercourses (Liu et al, 2019). However, many monitoring programs, mostly at low latitudes, focus on large watercourses, neglecting the extent of water quality impacts and preventing measures to control pollution in low order streams (Loiselle et al, 2017;Saltarelli et al, 2018).…”

Using water quality indices (WQIs) is one way to monitor watercourses for water quality. Currently, there is a lack of information about their behavior in the diurnal cycle because sampling is often carried out in the morning. Also, few articles focus on assessing the urban impact on the spatial variability of WQIs in tropical first‐order streams. Such streams receive many pollutants varying in intensity according to population habits, justifying the possible diurnal variation in water quality in addition to climatic attributes. This paper aims to evaluate the fluctuations in Brazilian WQIs and their parameters (temperature, turbidity, total solids [TS], hydrogen potential, dissolved oxygen [DO], biochemical oxygen demand [BOD], total phosphorus [TP], total nitrogen [TN], and Escherichia coli) between the morning (8 AM), afternoon (2 PM), and night (7 PM) periods for an urban first‐order tropical stream. Overall, the lowest DO concentrations and highest values of TS, turbidity, BOD, TP, TN, and E. coli were obtained in the morning, possibly representing population habits: the greatest generation of pollutants occurs overnight and in the early morning because there are clandestine domestic wastewater inputs into the stream, whose hourly periodicity generates a similar periodicity in the WQI of the evaluated stream. Although there was a significant variation in WQI average values between morning (15.50 ± 1.97) and afternoon (20.83 ± 5.42) only during the dry season (p < 0.05), different results were common throughout the day in all months, and the water quality was often classified in distinct categories: very bad, bad, and regular. Our findings present another dimension to be considered when assessing urban water quality, leading to direct benefits to the management and use of urban waters.
