IDENTIFYING POLLUTANT SOURCES AND CULTIVATING AQUATIC STEWARDSHIP WITH LARGE-SCALE PARTICIPATORY SCIENCE
Excess nutrients have created eutrophic conditions in 2/3rds of freshwater ecosystems. Two major factors impede restoring these compromised ecosystems. First, nutrient transport through river networks is extremely variable in space and time due to large swings in water flow, biological activity, and human disturbance. Second, a lack of public engagement with water quality issues reduces sociopolitical motivation to implement best practices. To address both issues, we organized a large participatory science project in the 10,000 km2 Utah Lake watershed, which is listed as impaired for excess total phosphorus and dissolved solids. We collaborated with several hundred members of the public, including K-12 and university students to sample ~250 sites three-times in 2018. We analyzed this rich spatiotemporal dataset to identify critical source areas, quantify spatial stability of water chemistry, and assess human and natural risk factors for eutrophication. We conclude that participatory science can extend scientific observation and improve public awareness and mentality, influencing how water resources are managed. Participatory water quality monitoring is not only a means of generating scientific understanding of catchment hydrology, it is a mechanism to encourage sustainable stewardship and improve water quality.
