Over the past two decades, the lake's water levels have steadily dropped. Water conditions in the Sea, characterized by low oxygen and high nutrient levels, favor the production of hydrogen sulfide (H<jats:sub>2<\/jats:sub>S). This study investigates the connection between the Sea's changing conditions, particularly the worsening water quality, and H<jats:sub>2<\/jats:sub>S emissions using air quality and water quality data collected since 2013 and 2004, respectively. H<jats:sub>2<\/jats:sub>S concentrations often exceed California's air quality standards, particularly in areas near the Sea during summer months. Wind patterns substantially impact detection of H<jats:sub>2<\/jats:sub>S. When wind is blowing from the Sea toward communities with sensors, located to the northwest of the Sea, H<jats:sub>2<\/jats:sub>S is detected significantly more often. Current monitoring efforts underestimate the frequency and distribution of H<jats:sub>2<\/jats:sub>S that exceeds air quality standards. An air sensor deployed in shallow water over the Salton Sea by a community science program detected substantially higher concentrations of H<jats:sub>2<\/jats:sub>S, particularly when wind was blowing over exposed sediment and shallow water, suggesting that these are a significant and overlooked H<jats:sub>2<\/jats:sub>S source at the Salton Sea. These findings highlight the need for improved air quality monitoring and more effective environmental management policies to protect public health in the region. The study emphasizes the importance of community\u2010led solutions and provides insights relevant to other regions experiencing similar environmental crises.<\/jats:p>","DOI":"10.1029\/2024gh001327","type":"journal-article","created":{"date-parts":[[2025,5,31]],"date-time":"2025-05-31T09:50:21Z","timestamp":1748685021000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Hypereutrophication, Hydrogen Sulfide, and Environmental Injustices: Mechanisms and Knowledge Gaps at the Salton Sea"],"prefix":"10.1029","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-3062-6898","authenticated-orcid":false,"given":"Diego","family":"Centeno","sequence":"first","affiliation":[{"name":"Department of Earth, Environmental, and Planetary Sciences Brown University  Providence RI USA"},{"name":"Department of Civil and Environmental Engineering University of California Los Angeles  Los Angeles CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alejandra G.","family":"Lopez","sequence":"additional","affiliation":[{"name":"Department of Earth, Environmental, and Planetary Sciences Brown University  Providence RI USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aydee","family":"Palomino","sequence":"additional","affiliation":[{"name":"Alianza Coachella Valley  Coachella CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juliana","family":"Taboada","sequence":"additional","affiliation":[{"name":"Alianza Coachella Valley  Coachella CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryan","family":"Sinclair","sequence":"additional","affiliation":[{"name":"Department of Environmental Microbiology Loma Linda University  Loma Linda CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Quinn","family":"Montgomery","sequence":"additional","affiliation":[{"name":"Department of Earth, Environmental, and Planetary Sciences Brown University  Providence RI USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Consuelo","family":"Marquez","sequence":"additional","affiliation":[{"name":"Independent Researcher  Coachella CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Migdalia N.","family":"Sanchez","sequence":"additional","affiliation":[{"name":"University of California Berkeley  Berkeley CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isabella B.","family":"Arzeno\u2010Soltero","sequence":"additional","affiliation":[{"name":"Department of Civil and Environmental Engineering University of California Los Angeles  Los Angeles CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0487-8518","authenticated-orcid":false,"given":"Mara A.","family":"Freilich","sequence":"additional","affiliation":[{"name":"Department of Earth, Environmental, and Planetary Sciences Brown University  Providence RI USA"},{"name":"Division of Applied Mathematics Brown University  Providence RI USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"13","published-online":{"date-parts":[[2025,5,31]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.envres.2010.11.008"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.3390\/geosciences8120438"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.scitotenv.2012.01.067"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","unstructured":"Arzeno\u2010Soltero I.
