The Salton Sea is a saline lake in California, USA that is fed mainly by runoff that contains high nutrient and pollution loads from agriculture and wastewater. Established in 2021 as a project of the environmental justice campaign of the grassroots organization Alianza Coachella Valley, the Salton Sea Environmental Timeseries (SSET) is a collaboration between community scientists — who are local residents in the predominantly Latinx and Indigenous environmental justice communities surrounding the Sea —, professional scientists based at universities, and community organizers. SSET was established to address the lack of accessible data on the Salton Sea despite the large environmental health impact of this impaired waterbody. SSET community scientists learn skills in scientific fieldwork, data analysis, and advocacy while collecting data that is used in advocacy for improved water quality and air quality. Collaborative projects have included presenting the data using infographics, creating a public facing website to make data accessible, public comments, and public webinars presenting the water quality results. Lessons learned and methods for building an inclusive community science program will be shared in this presentation.
