Supporting data – Urban Stream, Cardinal Court, ISU, Normal, November 9, 2023 to May 1, 2025

Between November 9, 2023 to May 1, 2025, water samples were collected upstream and downstream along a segment of a stream adjacent to Cardinal Court on the Illinois State University campus. At each location, samples were collected at the surface. In-situ measurements of Dissolved Oxygen, Specific Conductance, and Temperature were recorded with a YSI 85. Anion samples were analyzed using a Ion Chromatograph for fluoride (F-), chloride (Cl-), nitrate as nitrogen (NO3-N), phosphate (PO43-), and sulfate (SO42-). The available dataset provides the recorded field parameters and the analyzed ion concentrations.
