Geochemistry of subterranean outfalls and the Olentangy River in Columbus Ohio

This dataset includes inorganic chemistry and stable water isotope measurements of the Olentangy River and two subsurface pipe networks that drain The Ohio State University campus in Columbus, Ohio. Data were collected from November 2021 - November 2022 on a weekly or biweekly basis. Samples were collected for major cation (Na, K, Ca, Mg), anion (F, Cl, Br, SO4), nutrient (N-NO3, soluble reactive phosphorus) and dissolved silica. Additional samples were collected with no headspace for δ18O and δ2H measurements. All samples were collected with a sample poll device that was rinsed 3 times with sample water prior to collection. Samples for ion, nutrient, and dissolved silica analysis were filtered within 12 hours.

These data were originally published in the following reference, and further information may be found within:
