ORIGINAL RESEARCH published: 10 January 2020 doi: 10.3389/fenvs.2019.00202 Organic Matter Is a Mixture of Terrestrial, Autochthonous, and Wastewater Effluent in an Urban River Julia E. Kelso 1,2* and Michelle A. Baker 2 1 Oak Ridge Institute of Science and Education, Washington, DC, United States, 2 Department of Biology and the Ecology Center, Utah State University, Logan, UT, United States Terrestrially derived organic matter (OM) is known to dominate the OM pool in reference watersheds. Urban watersheds are known to receive large OM loads compared to reference watersheds, but the proportion of terrestrial, autochthonous, and anthropogenic (e.g., wastewater effluent) sources of OM in urban watersheds remains unknown. Organic matter was identified as a pollutant of concern in the Jordan River, an urban river in the Salt Lake Basin, U.S.A.
